20 Jul Branch Event
Greenwood Park, Chiswell Green near St Albans - 7 new members attended our annual new members day. John Murray and Andrew Wood showed the contents of their moth traps, with a fine array of species on show (list to follow). Ian Small provided an introduction to the branch, Liz Goodyear gave tips on species identification and butterfly gardening, Andrew Wood provided a handy guide to butterfly recording and Malcolm Hull gave information on how to get involved with branch activities.
The afternoon butterfly walk visited the wildflower meadow and the recently constructed butterfly bank. Species recorded included Red Admiral, Comma, Small Tortoiseshell (caterpillar stage only), Peacock, Brown Argus, Small Copper, Large, Small and Essex Skippers, Large and Small Whites, Marbled White, Meadow Brown, Gatekeeper, Ringlet, Holly Blue, 6-spot Burnet moth and Cinnabar (caterpillars). We were pleased to see hundreds of Kidney Vetch seedlings growing on the butterfly bank. The Birdsfoot Trefoil plants have been chewed by rabbits, but are regenerating from the existing rootballs

19 Jul This morning, I saw a Jersey Tiger shortly after leaving Boston Manor tube station Michael Robinson
19 Jul St Albans Shed - 7 Small Tortoiseshells now hibernating in my shed up from 2 last week. Last year I had a total of 13 Small Tortoiseshells hibernating in the shed. On that basis, 50% of the population have already entered hibernation before the Big Butterfly Count has begun. This may explain the disappointingly low numbers of this species recorded on the Count Malcolm Hull
18 Jul Hounslow. After morning rain this was an afternoon walk: Gatekeeper: 97, Meadow Brown: 66, Peacock : 23, Speckled Wood: 11, Holly Blue: 2 Green-veined White: 7, Small White: 14, Ringlet: 5, Purple Hairstreak: 2, Small Heath: 5, Brown Argus: 2, Small Skipper: 5, Comma: 8, Marbled White: 2, Red Admiral: 1, Essex Skipper: 2, Common Blue: 1, Small Copper: 1 Peter Gore

Moths were Mother of Pearl x 3, Small Scallop x 1, Shaded broad-bar x 15, Yellow Shell x 19 David Gower
17 Jul Symondshyde Great Wood. 19 Silver-washed Fritillary counted along full length of sunny glade this afternoon. Many more than on my last visit two weeks ago. Many Ringlets and also Comma 6, Peacock 3, Red Admiral 2, Brimstone 3, Small Skipper 4, Gatekeeper Trevor Chapman
17 Jul Hounslow. Gatekeeper: 104, Small White: 27, Meadow Brown: 81, Essex Skipper: 1, Ringlet: 6, Speckled Wood: 11, Peacock: 36, Holly Blue: 1, Purple Hairstreak: 1, Green-veined White: 5, Red Admiral: 5, Comma: 6, Brown Argus: 3, Marbled White: 3, Small Skipper: 5, Small Heath: 5, Large White: 2, Large Skipper: 1, Common Blue: 1 Peter Gore

I then had an extended walk around Balls Wood: Comma 5, Skippers (large and small) 30, Gatekeeper 43, Ringlet 100+, Large White 18, Green-veined White 7, Meadow Brown 11, Peacock 47, Speckled Wood 11, Silver-washed Fritillary 6, White Admiral 2, Marbled White 6.

17 Jul St Albans - Verulamium Park/King Harry Lane - 2 White-letter Hairstreaks, including one down low nectaring on Cow Parsley. Fresh emergences of Peacock, Brown Argus and Small Copper also noted. All the usual browns and whites, plus good numbers of Small Tortoiseshell plus Red Admiral, Comma and at least 16 Small/Essex Skippers.
Nomansland Common - my first Silver-washed Fritillary at this site. Two sightings of Purple Emperor flying along the top of the oak canopy at the high point - a meagre result from 3 hours. Since the species colonised this area a few years back, numbers spotted at this site and the adjoining Heartwood Forest have been comparable until this year. The rapid expansion of the Heartwood Purple Emperor numbers is probably linked to the abundance of Sallow on that site, there is very little at Nomansland. 6 Peacocks, 17 Purple Hairstreaks, 1 Small Heath, 6 Small Copper, 2 Red Admiral, 3 Comma, 1 Brown Argus, the usual Browns and whites, 36 Small/Essex Skippers, with positive ID for both. Good to see the site management works we agreed last year with CMS and Herts Moth Group have been implemented, with scrub encroaching on the heather area removed and a new clearing created in a dark part of the wood
Malcolm Hull
17 Jul 4 Peacock at Trent Park. 1 male Common Blue, 1 Brown Argus and 1 Small Copper at Vicarage Farm, Enfield (TQ 3097) at 10:40 hrs, also here 1 Peacock, 2 Small Skipper and 1 Essex Skipper.

16 Jul Box Tree moth invasion in St Albans - saw my first ever here two days ago, two in my garden this evening and now one in my kitchen. Been dreading this for a while, working on a plan to persuade my neighbours not to spray all their hedges. I'm worried spraying could have a major harmful impact on butterflies in my garden Malcolm Hull
16 Jul Purple Emperor and Silver-washed Fritillary at Patmore Heath Gavin Vicary

15 Jul It turned out warm at lunchtime so I decided last minute to do my transects and WCBS at Great Northaw Wood. I was rewarded with sightings of several Silver-washed Fritillaries and finally got one to settle. I'm on the lookout for Dark Green Fritillaries there as the warden reckons she has seen them. The Ringlets and Meadow Browns are still in high numbers. There were more Purple Hairstreaks visible lower down. The Commas are also becoming regular again Dee Cullen
15 Jul I spent the afternoon at Hampstead Heath. The Purple Emperor duly appeared just after 13:00 and was seldom out of view for long after that, either perched or making a short or longer flight. At 16:15 and with the sun now fully out he became galvanised and a flurry of activity ensued. A second Purple Emperor suddenly appeared and a terrific clash and chase followed, with two minor ones thereafter. A couple of Red Admiral had been about earlier, avoiding the Emperor's attentions but now one of them began to seriously irritate the him and I watched as it was pursued furiously a number of times. Finally a particularly annoying Purple Hairstreak became locked in an in an interminable contest with our hero. Things wound down at 16:45 Frank Nugent
15 Jul Pinner garden: Small Tortoiseshell nectaring on marjoram. Gatekeeper also on Marjoram & Peacock in classic pose on Buddleia plus assorted whites in flight Tony & Gill Porter
15 Jul Hounslow. A day which turned out sunnier than forecast, plenty of butterflies around to take advantage of the conditions: Red Admiral: 9, Meadow Brown: 87, Peacock: 38, Speckled Wood: 10, Gatekeeper: 74, Purple Hairstreak: 6, Green-veined White: 6, Ringlet: 14, Small White: 19, Comma: 7, Small Skipper: 8, Brown Argus: 4, Holly Blue: 4, Common Blue: 1, Small Tortoiseshell: 1, Essex Skipper: 2, Small Copper: 2, Marbled White: 2 Peter Gore

13 Jul Branch Event
Heartwood Forest, near St Albans - Our moth trap event with the Woodland Trust was a great success, with 5 traps, 16 people attending and many thousands of moths trapped. John Murray has enlisted the help of Mark Sterling, who contributed two extra generators and considerable expertise to a highly enjoyable evening. Oak Eggar was the first substantial moth in the trap, with both males and a female seen during the evening. Thousands of micros including many grass veneer appeared along with more exotic large Elephant Hawk-moths, Drinker moths, Black Arches, Swallow-tailed, Brimstone, Ruby Tiger, Peach Blossom and many more - full list here
Even a Meadow Brown butterfly got in on the act. As we moved from trap to trap, we noticed differences in the range of species in the meadow and by the wood edge. Best results were from the traps most sheltered from the stiff breeze, though all yielded good results. Taking the traps down at around 1am, the air was thick with moths adding to many hundreds perched in and around the traps and sheets. A memorable evening, particularly special because of John's and Mark's amazing knowledge of all the names, including micros

13 Jul Heartwood Forest, near St Albans - Inspired by yesterday's sightings of Purple Emperor by Andrew Steele and Mark Sterling, I headed up to Wells/Pudler's Wood at Heartwood. I didn't get home from last nights branch moth trap (see separate report) at the same location until 2am, so only arrived about 1pm. In three hours I had a total of 26 Purple Emperor sightings and from their behaviour I estimate there were at least 6 different individuals, quite likely more. Behaviours seen included males cruising round two different high points in the canopy, very rapid flight of a male apparently fleeing a clash, nectaring on lime tree blossom and flying into Sallows in The Magical Wood. Never seen so many before in Herts. It's only 3 years since David Hunt's first sighting at this site and more evidence that rewilding projects like Heartwood can create ideal habitat for this species.
Oak Eggar was much in evidence, zooming around at high speed, one even crashed into my face at full speed. Like me the Oak Eggars had been at the moth trap the night before, maybe the bright lights had affected its vision? Other species recorded on this trip included Burnet Companion, Both Narrow-bordered Five-spot & Six-spot Burnet, Cinnabar, Red Admiral, Peacock, Small Tortoiseshell, Purple Hairstreak, Ringlet, Marbled White, Gatekeeper, Meadow Brown, Large, Small & Green-veined Whites, Large, Small & Essex Skippers

13 Jul My son and I were thrilled to see our first Comma at Finch Lane Allotments, Bushey. Also seen here: 6 Gatekeeper, 3 Meadow Brown and a Dark Arches moth Rebecca Palmer
13 Jul At Drop Lane, Bricket Wood this morning: Essex Skipper x 4, Small Skipper x 4, Marbled White x 1, Gatekeeper x 1. Onto Bricket Wood Common seeing Meadow Brown x 41, Ringlet x 52, White Admiral x 1, Brimstone x 1, Gatekeeper x 7, Marbled White x 25, Small Skipper x 3, Silver-washed Fritillary x 2, Small Heath x 1, Small White x 1, Purple Hairstreak x 9, a lot of activity low down on ferns. No Purple Emperors David Gower
13 Jul Hounslow. I started out early this morning to catch the sun but in truth it felt as though butterflies were determined to fly regardless of cloudy conditions in the early afternoon. After my comment yesterday it's apparent that Meadow Browns wish it to be known that they've certainly not passed their peak. My own highlight though was a fresh and beautiful female Small Copper, I hope the first of many. It's perhaps also worth highlighting that despite over 300 butterflies today not one of them was a Painted Lady. It will hardly be surprising if this absence doesn't last but after so many and so long I think worth the emphasis just in case it is the end of a memorable year here for them. Here's the full list: Gatekeeper: 62, Red Admiral: 10, Speckled Wood: 17, Meadow Brown: 111, Small White: 25, Purple Hairstreak: 1, Peacock: 26, Green-veined White: 9, Ringlet: 18, Small Skipper: 16, Marbled White: 3, Comma: 7, Holly Blue: 2, Small Heath: 3, Small Copper: 1, Brown Argus: 1, Essex Skipper: 3 Peter Gore
13 Jul 1 Scalloped Oak at Dalrymple Close, N14 and 1 Least Carpet at Chase Rd/Charter Way, N14 this morning. 1 Red Admiral near Hadley Rd/Vicarage Farm and 2 Red Admiral and 1 Comma at Park Farm, Enfield (TQ 2998) Robert Callf
12 Jul Hexton Chalk Pit (TL107299): Chalkhill Blue (3 males), Dark Green Fritillary (20+). It's early days still for the Chalkhills, but this looks like turning into a poor year for them at their North Herts. sites. On the other hand, Dark Green Fritillaries are having an exceptional year both here and on Therfield Heath. Other species seen: Small Skipper, Marbled White, Green-veined White, Meadow Brown, Ringlet and Gatekeeper Martin Johnson
12 Jul Hounslow. Peacock and Speckled Wood on the increase as Meadow Brown, Small Heath, Marbled White and Skippers decline from their peak. I've also had my annual encounter with a Brimstone on Perennial Sweet Pea, pretty much the same area as other years too. I could believe it was the same one if I didn't know better. This is the full list: Holly Blue: 3, Small White: 9, Gatekeeper: 21, Meadow Brown: 55, Speckled Wood: 10, Marbled White: 2, Purple Hairstreak; 2, Comma: 10, Peacock: 16, Ringlet: 8, Small Tortoiseshell: 5, Small Heath: 3, Painted Lady: 2, Red Admiral: 3, Essex Skipper: 6, Brimstone: 1, Small Skipper: 3, Large Skipper: 3 Peter Gore
12 Jul Saw my first Peacock of the new generation in field north of Wintergreen Wood (Knebworth transect) Peter Clarke
12 Jul Aldbury Nowers - 2 Dark Green Fritillaries and 2 Silver-washed Fritillaries. Absolute masses of Marbled Whites, they seem to be having a great year. Nearly as many Meadow Browns, but fewer Ringlets at this dry site. Gatekeeper numbers are still increasing and Small/Essex Skippers seem a bit better this year. Other species spotted: Red Admiral, Large Skipper, Painted Lady, Brimstone, Large and Green-veined Whites, Small Heath and Speckled Wood. Also my first 6 spot Burnet moths of the year.
Back in St Albans, the first two Small Tortoiseshells have entered into hibernation in my shed at some stage during the last week

7 Jul Hounslow. An afternoon walk after morning rain. Although the whole area was visited, trivial circumstances conspired against me, so the following is a far from complete list of everything flying: Speckled Wood: 2, Ringlet: 12, Meadow Brown: 34, Holly Blue: 1, Comma: 1, Red Admiral: 2, Small Heath: 1 Small Tortoiseshell: 1, Marbled White: 2, Gatekeeper: 1, Small White: 1, Comma: 1, plus plenty of unrecorded Skippers Peter Gore
7 Jul St Albans - Small Tortoiseshell and Comma both nectaring on the purple buddleia in my garden this afternoon. My first buddleia butterflies of the year! Malcolm Hull
7 Jul At 1:25 pm at Norton Green Common, I saw a Purple Emperor fly over one of the oaks on the SW edge of Watery Grove. This oak is behind the birch tree where a male was found during a field trip in 2016 Peter Clarke
7 Jul Branch Event
Bricket Wood Common, St Albans - Cloudy skies, 15 degrees, light drizzle and a dismal weather forecast all indicated this might not be a successful walk. Despite this 11 people showed up and their faith was rewarded. All three target species, White Admiral, Silver-washed Fritillary and Purple Emperor were recorded, albeit in low numbers. Purple Emperor stole the show, with both a male and a female found on the ground and photographed by all. Both came readily to my hand and the male sat there happily for 20 mins as we continued with our walk.
Marbled Whites, Meadow Browns and particularly Ringlets were all in good numbers, with a few Large, Small and Essex Skippers, Small and Green-veined Whites, Red Admiral, Comma and Gatekeeper also recorded. Purple Hairstreaks were active in the canopy and we also saw half a dozen flying low. After the walk ended Chris Newman and I saw a Small Heath, which has reappeared on the Common this Spring after an absence of several years. In Mutchetts Wood we saw many more Purple Hairstreaks and Chris caught two glimpses of Purple Emperor in flight through a gap in the canopy

7 Jul Branch Event
A good walk across Hertford Heath and Balls Wood for today's Field Trip. We had excellent views of Small, Essex and Large Skippers, Large, Small and Green-veined Whites, Comma, Silver-washed Fritillary, Marbled White, Ringlet, Gatekeeper, Meadow Brown and more fleetingly White Admiral. Particularly at the end there were many Purple Hairstreaks on oaks at the very edge of the Heath

6 Jul Branch Event
We were joined by three other people for the annual Purple Emperor assembly site visits. Unfortunately the weather changed overnight from lovely sunshine to wall to wall cloud at 1 o'clock when we started watching the woodland edge at Fir and Pond Wood. A few Purple Hairstreak were seen through binoculars but no Purple Emperors flew (which we half expected). We then went on to the assembly area at Northaw Great Wood. This is viewed from underneath so we were slightly more optimistic that one might fly. Despite cloud, it was warm (about 22 degrees) and not too windy. It wasn't long before a single Purple Emperor left its perch and flew over the oak but it took a while for it to return and make several flights; then perch in view of all those below. Leaving everyone very satisfied, however it got better when he was joined by a second Purple Emperor, and several chases and clashes were observed before the singleton took control of the oak tree and perched up, occasionally making a solitary flight to check its surroundings. Purple Hairstreak were also flying with one being chased by the Purple Emperor. So despite the cloud, a very successful visit despite the earlier disappointment at Fir & Pond Wood. However, everyone now knows where to look in future

6 Jul Hounslow. A morning walk catching early sunshine which soon departed, leading to reduced sightings. Inevitably after yesterday's comment, Red Admirals 'returned' today, including one individual that appeared from nowhere high on the front of my shirt as if to make some sort of sarcastic point. I can think of half a dozen species I'd be happy to have respond in similar fashion between now and the end of the season but in the meantime here are today's: Meadow Brown: 84, Small White: 11, Speckled Wood: 2, Purple Hairstreak: 4, White-letter Hairstreak: 1 Painted Lady: 2, Gatekeeper: 2, Large Skipper: 2, Ringlet: 30, Red Admiral: 3, Green-veined White: 4, Comma: 4, Small Heath: 10, Small Tortoiseshell: 1, Small Skipper: 5, Essex Skipper: 3, Marbled White: 9, Common Blue: 1 Peter Gore

6 Jul Marbled White in Letchworth garden Deborah Parfitt
5 Jul I went for a wander down Watery Grove / Norton Green Common this morning. Pleased to see 1-2 Purple Hairstreaks at 3 spots, not bad considering around 6.15am - 7.30am! Best views were just outside the other end of Norton Green common in oaks at edge of Knebworth woods. Scanned tree tops for emperors but no sign Tom Speller
5 Jul 5 Silver-washed Fritillaries at Scales Park Woods (near Anstey) Martin Johnson
5 Jul Purple Emperor by Well Wood, Heartwood Forest Martin Webb
5 Jul Ringlet in Muswell Hill garden at nearly 9:00pm Dee Cullen
5 Jul Hounslow. Perhaps the most surprising thing today on a rather cloudy afternoon was the absence of Red Admiral - 8 yesterday so maybe another migrant finding us wanting although there always seems like plenty of nettles to me. Here's the day's full list: Meadow Brown: 115, Ringlet: 18, Small Heath: 13, Green-veined White: 6, Speckled Wood: 3, White-letter Hairstreak: 2, Purple Hairstreak: 3, Comma: 6, Marbled White: 9, Small Skipper: 7, Gatekeeper: 2, Painted Lady: 4, Small White: 9, Small Tortoiseshell: 1, Essex Skipper: 6, Large Skipper: 4, Common Blue: 2, Brown Argus: 1, Holly Blue: 1 Peter Gore
5 Jul At least 1 Large White - St Faiths Close, Hitchin David Inward
5 Jul 4 Small Tortoiseshell at Vicarage Farm, Enfield (TQ 3097). At Park Farm, Enfield (TQ 2998) - 1 Purple Hairstreak, 1 Red Admiral, 1 Painted Lady, 1 Marbled White and a male Gatekeeper near Hadley Rd - my first of the year. 2 male Gatekeeper at Trent Park (1 near Oakwood entrance, 1 Sect 5 'New Fields'), 1 Comma near Oakwood entrance, Trent Park. 1 Small Tortoiseshell at Southgate Chase Allotments at 13:45 hrs. 1 Meal Moth Pyralis farinalis at ASDA Southgate Robert Callf

No Purple Emperors or White Admirals Peter Clarke
5 Jul My first Gatekeeper of the season at Waterford Heath south Steve Kiln
4 Jul Walking the Bricket Wood Common Butterfly Transect in the afternoon, I saw what looked like a female Silver-washed Fritillary, except it looked grey-brown rather than orangey-brown. I spent almost half an hour trying to get a decent wing-open photo, with limited success. When I got round to checking whether my photos showed SWF markings, I found that it is a recognized variant, the valezina form. Walking home 2½ hours after I first spotted her, she was still in the same area, probably egg-laying on an ash tree, between the footpath and an overgrown section of the 'Gas Ride' Chris Newman
4 Jul 4 Silver-washed Fritillaries by wood, Ellenbrook Fields Martin Webb
4 Jul While walking across Bunkers Park, had amazing numbers of Marbled Whites and Meadow Browns, nectaring on Knapweeds and Bramble. Also small numbers of Ringlet and Essex Skipper Clive Burrows
4 Jul On my transect had 1 Purple Emperor in usual area by the pond by Wells Wood and Purple Hairstreak in the same area at Heartwood Forest Andrew Steele
4 Jul Went to Broxbourne Woods this morning, saw Hummingbird Hawk-moth on top path feeding on Self Heal. Lots of Purple Hairstreaks, Silver-washed Fritillary, Marbled Whites. Then late afternoon saw another Purple Emperor at Turnford, this time by the causeway which leads to the bridge over the Lea Canal. It was trying to take moisture from a stick which was in the water Kevin Standbridge
4 Jul Bowers Heath near Harpenden - 1 Humming Hawk-Moth & 4 Purple Hairstreaks late afternoon. Weedy field, Batford - 3 White-letter Hairstreaks late afternoon Darin Stanley
4 Jul In the Broxbourne Woods complex from roughly 10.00-13.30. At the first site I visited (Broxbourne Woods, West car park) I had a pristine male Purple Emperor at 10.25am at approx TL326072. It was flying at roughly knee height initially but soon climbed and disappeared through a sallow. I suspect that it might have been on the ground just prior to me noticing it. No more sightings in approx the next hour. I next visited Wormley Wood S end and also Bencroft Wood but no further encounters. Just one White Admiral surprised me. By contrast Silver-washed Fritillaries were out in good numbers but not really nectaring a great deal Andy Culshaw
4 Jul 31 Meadow Brown, 85 Marbled White, 7 Small/Essex Skipper, 1 probable Common Blue, 1 Large White - meadow and plantation east of Greenway north of Willian Road, near Hitchin (TL2030) (whole field probably has at least double these numbers). 5 Large White - field off Queenswood Drive, Hitchin (TL2030). 1 Large White - north of Sainsburys, Hitchin (TL186295). 1 Red Admiral, 1 Large White - St Faiths Close, Hitchin (TL198303) David Inward
4 Jul Hounslow. Brimstone and Peacock back with us here today on a very warm sunny afternoon: Red Admiral: 8, Painted Lady: 2, Meadow Brown: 102, Ringlet: 27, Brimstone: 1, Small Heath: 29, Comma: 8, Purple Hairstreak: 2, Small White: 7, Green-veined White: 3, Holly Blue: 3, Marbled White: 12, Small Tortoiseshell: 1, Large Skipper: 6, Small Skipper: 7, Essex Skipper: 4, Common Blue: 1, Gatekeeper: 2, Peacock: 2 Peter Gore
4 Jul Some Highlights from a visit to Therfield Heath (west of the Sporting Club) this morning: Chalkhill Blue (6 males, all but one on Church Hill), Essex Skipper (1+), Small Skipper (20+), Brown Argus (2; one worn, one apparently fresh: very early 2nd generation??), Small Tortoiseshell (2+), Gatekeeper (5), Dark Green Fritillary (40+). Numbers of Dark Green Fritillary continue to grow year on year - given that possibly all the butterflies I saw were males, I estimate that there could be over 200 individuals of this very attractive butterfly present on The Heath now and they are also spreading out into the nearby farmland. All 25 of our resident species are now (or have been) on the wing this year. There are still hundreds of Meadow Browns and Marbled Whites flying, too Martin Johnson
4 Jul 3 Green-veined White settled on field margin at Park Farm, Enfield (TQ 2998) before 08:00 hrs, also here 1 Painted Lady, 1 Red-belted Clearwing on concrete path at Park Farm, Enfield (TQ 293 982) at 08:05 BST - my first record of a Clearwing sp in the Enfield area, 1 Small Tortoiseshell at Hadley Rd/Park Farm at 08:23 hrs, 1 Comma edge of Moat Wood, Trent Park Robert Callf

3 Jul One male Purple Emperor holding territory, chasing Wood pigeons at Thorley Lane east Bishop's Stortford, in the gap I found last year Laurence Drummond
3 Jul I have had a couple of excursions to Cassiobury Park and Whippindell Woods this week in preparation for Sundays butterfly walk to see what's on the wing. White Admiral are on the wing and once more 'Camilla Oak' seems to be a favourite spot for White Admiral as seen on last years walk, numbers of Silver-washed Fritillary are on the increase and on Saturday the first White-Letter Hairstreak was seen. Weather permitting we shall go and look for these species on Sunday. If favourable there is a good chance of seeing White Admiral low down among the oaks and brambles. Also by Sunday Purple Hairstreak should also be on the wing. In the park I saw all three golden Skippers today, ( one confirmed sighting of the Essex Skipper ) Marbled Whites and lots of Ringlets and Meadow Browns. Sadly the walk does clash with other walks but if you are in the area and like to check out Whippendell Woods for butterflies then please join us at 2pm Sunday Peter Fewell
3 Jul I set off around my usual route at Stanwell Moor at around nine this morning, and set about one of my periodic counts of what was flying: Meadow Brown 83, Small/Essex Skipper 44, Small White 27, Small Heath 21, Red Admiral 10, Comma 8, Green-veined White 4, Small Tortoiseshell 4, Common Blue 4, Large Skipper 3, Large White 2, Ringlet 1, Marbled White 1, Painted Lady 1, Brown Argus 1, Holly Blue 1, Brimstone 1, Gatekeeper 1.
The total of 19 species is the highest I have ever recorded here in one day, and remarkably Speckled Wood is not on the list. The Gatekeeper was my first of the year here; The Brimstone was a new season individual; Two of the Common Blues were new second brood examples, as was the Holly Blue. Finding a single Ringlet among all those Meadow Browns wasn't easy, but I have a record of it! Both Small and Essex Skippers were definitely present. From sampling those I saw I would estimate roughly a 3:2 ratio in favour of Small over Essex

2 Jul Hounslow. The first Gatekeeper of the year today. Ringlet numbers are steadily increasing as are Skippers but I'm not making a very good job of recording the latter I fear. Whites also visibly on the increase and not fully recorded but not so numerous : Ringlet: 29, Marbled White: 5, Meadow Brown: 115, Small Heath: 32, Painted Lady: 5, Speckled Wood: 2, Purple Hairstreak: 4, Comma: 6, Small Skipper: 11, Small White: 5, Gatekeeper: 1, Red Admiral: 3, Essex Skipper: 1, Green-veined White: 2, Large White: 1, Large Skipper: 1, Holly Blue: 1 Peter Gore

1 Jul At 4.45AM. I was walking down my Watford garden to go into the house, to make my second mug of tea. I was half way through emptying my moth trap. I disturbed a low down female Purple Hairstreak. It alighted on an Alder Buckthorn bush and stayed long enough for a photograph. Unfortunately it was windy and so the photo isn't brilliant. Our garden is surrounded by Oaks Paul Williams
1 Jul Saw my first Silver-washed Fritillaries (3) in 4 years at Bayfordbury (TL3110) while walking a transect.

1 Jul Saw my first Purple Emperors high up, two flitting between an Oak and an Ash at the known spot near the entrance driveway at Northaw Wood at around 5.30 - thanks Andrew Middleton for the help re location. I deliberately did my transects late here in the hope I'd see them and Purple Hairstreaks. I also saw six or so of them, again, high on the oaks. A purple day! Dee Cullen
1 Jul Hounslow. Started early so mostly a morning walk with slightly lower numbers resulting. Although numbers are not huge, confirmation from another local that Marbled White may be having its best year here and it has certainly spread from what used to seem to be its Marshalling Yards base to more or less everywhere across the site.: Meadow Brown: 83, Purple Hairstreak: 3, Ringlet: 17, Small White: 5, Large Skipper: 4, Small Skipper: 10, Small Heath: 22, Green-veined White: 2, Speckled Wood: 1, Comma: 6, Marbled White: 4, Red Admiral: 2, Small Tortoiseshell: 2, Painted Lady: 2, Common Blue: 1, Brown Argus: 1 Peter Gore

30 Jun Walked through Tunnel Gardens around 11.00am: 5 Large Skipper, 2 Small Skipper, 6 Meadow Brown, 4 Ringlets, 3 white butterflies in flight one of which seemed like a Marbled White.
4.15 to 4.45 paid my first visit to Balls Wood after a cycle ride from Bayford Station only had time to walk down the main ride to the first intersection then left a bit to a sunny patch of brambles. 7 Large Skippers, 2 Comma, 2 White Admiral in flight but did not settle, 3 white butterflies in flight, numerous Meadow Brown and Ringlet including one that posed nicely for me.
18.00 returned to Tunnel gardens to see if I could find my suspected Marbled White and was excited to find a female settled on the thistles in one of the areas we have cleared of bramble, the first time I have ever seen one here. I had been meaning to go and look at Alexandra Palace after there was a report of one there. Tunnel Gardens, is not far along the main line from Ally Pally. I am hoping that as it was a female it might have laid eggs in the new meadow areas. I also saw a male Essex Skipper, a Cinnabar moth (the first I have seen here), 4 Large Skippers, 5 Meadow Browns, 1 Speckled Wood and four Ringlet
Miles Attenborough

30 Jun Heartwood Forest - after the butterfly walk I visited the Valley Field to check on the progress of the Kidney Vetch planted in 2017 as part of the Herts & Middx Small Blue Project. Pleased to report several thousand flowering plants, growing in areas with little grass and plenty of bare soil, so they should be able to self seed successfully. Additional butterfly species seen Small Blue, Red Admiral, Small Tortoiseshell Malcolm Hull
30 Jun Branch Event
Heartwood Forest, Sandridge near St Albans - a rather overcast morning for the family butterfly walk. Marbled Whites and Meadow Browns were in their hundreds, also good numbers of Ringlet and Small Heath. Small Skippers were less common - we checked at least 6 and all were Small. Other species in low numbers - Painted Lady, Large Skipper, Large White, Common Blue, Small Tortoiseshell and a possible Small Blue plus Cinnabar Moth

Lots of Marbled Whites and Meadow Browns and fewer Small Heath and Ringlets. I did not attempt to count them.

28 Jun Hounslow. Whilst unsuccessfully watching the Elms for some time for one Hairstreak I managed to spot the other, i.e. Purple Hairstreak more or less at my feet, the first so far this year at that level.It looked quite a worn specimen so I suspect there's been rather more going on up in the Oaks nearby than I've detected to date (which is very little). Here are the full sightings: Small Heath: 41, Comma: 8, Meadow Brown: 100, Purple Hairstreak: 1, Red Admiral: 8, Painted Lady: 2, Small White: 5, Ringlet: 10, Small Skipper: 5, Common Blue: 4, Green-veined White: 3, Small Tortoiseshell: 2, Speckled Wood: 2, Holly Blue: 1, Brown Argus: 1, Essex Skipper: 1, Marbled White: 1, Large Skipper: 6, Large White: 1 Peter Gore

Then cycled through Tunnel Gardens shortly after and saw two Red Admirals fighting over a sunny glade, two Specked Wood, two Painted Ladies, one beautifully fresh Comma and two Large Skippers. The Large Skipper, Comma and a Painted Lady were battling over a prime bit of sunny territory Miles Attenborough

27 Jun Some butterflies at Broxbourne woods this afternoon. Red Admiral=5, Painted Lady=6, Marbled White=10+, White Admiral=2, Speckled Wood=4, Silver-washed Fritillary=2 Christoper Benton
27 Jun My first Silver-washed Fritillary this afternoon at a private site I have access to north of Hertford. Also found a Holly Blue at Rickneys Quarry egg laying on Goats Rue. Two White Admirals on my Balls Wood Transect. A back garden first this afternoon in Hertford was Marbled White Andrew Wood
27 Jun Hounslow. I'm wondering if we'll have any Painted Ladies at all here by the end of the week. We're feeling rather rejected! Fresh Brown Argus today after tatty ones earlier in the week. Small Heath doing very well, Ringlets poor thus far. I'm under-counting Skippers and Whites but even if every individual glimpsed was included their numbers would still be low. Peacocks are around in one sense - I keep meeting their caterpillars wandering along the paths : Red Admiral: 6, Comma: 12, Painted Lady: 5, Ringlet: 3, Small Heath: 40, White-letter Hairstreak: 1, Purple Hairstreak: 3, Meadow Brown: 97, Large Skipper: 7, Marbled White: 1 Small Skipper: 7 Small Tortoiseshell: 4 Brown Argus: 3 Large White: 4 Speckled Wood: 2 Essex Skipper: 2 Common Blue: 1 Small White: 2 Peter Gore
27 Jun Roughly 12.30 to 15.00 at Bricket Wood Common this afternoon with a clear sky and 20C+ produced large numbers of Meadow Brown, 20+ Ringlet, several Speckled Wood and Small Tortoiseshell, 2 Brimstone, 4+ Large Skipper, 3 Painted Lady, 9+ Marbled White, and 2 Red Admiral. Walked the Gas Ride end twice end to end but no Hairstreaks or Fritillaries yet, and only 1 White Admiral - in Mutchetts Wood along the footpath running adjacent to the east side of the railway Peter Waldron
27 Jun Bricketwood - 1 White Admiral (north part of wood) Darin Stanley
27 Jun At Trent Park (12:40 - 14:00 hrs) - 2 Red Admiral, 5 Large Skipper, 7 Ringlet, 21 Small Heath, 14 Marbled White, 1 Small Copper (worn - first brood), a batch of Cinnabar caterpillars feeding on ragwort, 1 Painted Lady, 3 Comma including two together edge of Church Wood. 1 Brimstone Moth at Oakwood Station Robert Callf
26 Jun Batford - 1 Painted Lady in garden. Cooter End Lane near Harpenden - 1 Painted Lady Darin Stanley
26 Jun Cloudy day at Hexton chalk pit NR. Still plenty of butterflies about. Dozens of Marbled Whites, Painted Lady=3, Small Heath=20+, Meadow Brown=20+, Dark Green Fritillary=2 Christopher Benton
26 Jun Hounslow. Although there was far more sunshine and earlier than forecast numbers didn't match yesterday's despite a fresh Green-veined White and several Holly Blues : Small Tortoiseshell: 8, Painted Lady: 24, Ringlet: 6, Meadow Brown: 84, Small Heath: 27, Red Admiral: 5, Green-veined White: 1, Comma: 7, Holly Blue: 3, Small Skipper: 7, Large Skipper: 2, Common Blue: 6, Brown Argus: 1, Marbled White: 2, Large White: 1, Small White: 1 Peter Gore
26 Jun At Monken Hadley Common (13:45 - 15:00 hrs) - 8 Ringlet, female Holly Blue, 6 Large Skipper, 1 Blackneck (TQ 269 972) - my first record of this local moth species, 1 Yellow Shell, 1 Burnet Companion, 16 Marbled White, 4 Small Skipper, 3 Painted Lady and 1 Purple Hairstreak. At Covert Way LNR - 2 Ringlet, 1 Marbled White and 1 Large Skipper.
At Trent Park (15:00 - 15:45 hrs) - 5 Painted Lady, 1 Small Tortoiseshell and 3 Red Admiral. 1 Red Admiral at Bramley Parade, N14
Robert Callf
25 Jun Weedy field, Batford - 3 Painted Ladies, 1 White-letter Hairstreak, 1 Marbled White, numerous Meadow Browns Darin Stanley
25 Jun I went out at Stanwell Moor again in broadly similar weather (cloudy, humid, very warm), and saw the following: Meadow Brown 66, Painted Lady 29, Small Heath 18, Common Blue 12, Red Admiral 8, Large White 5, Small Tortoiseshell 4, Large Skipper 3, Brown Argus 3, Holly Blue 3, Small Copper 1, Small Skipper 1, Comma 1, Marbled White 1
There is obviously a big migration of Painted Ladies underway, but I reckon a few Red Admirals and Large Whites have come over with them! The Small Skipper is the first here this year, and one of the Brown Argus looked like a brand new butterfly, maybe a second brood. The Comma was a summer form f. hutchinsoni
Dave Miller
25 Jun A soaking wet afternoon at Balls Wood NR after torrential rain at dawn. Red Admiral=2, Painted Lady=3, White Admiral=2 (interacting above the brambles by the viewing platform), Holly Blue=1. Plus Meadow Browns, Ringlets and Large Skippers Christopher Benton
25 Jun Hounslow. After the morning rain had cleared this was another exhausting walk in very humid conditions with ever increasing numbers of butterflies. The most surprising sight, the last of 201 butterflies seen and identified, was a Marbled White at the junction of Argyle Road and The Avenue, the most urban setting I've ever seen this butterfly in - it may have travelled along the nearby railway. Here's what I did record: Small Heath: 21, Meadow Brown: 91, Ringlet: 6, Painted Lady: 50, Small Skipper: 4, Red Admiral: 4, White-letter Hairstreak: 1, Large Skipper: 2, Small White: 2, Comma: 4, Small Tortoiseshell: 5, Essex Skipper: 3, Speckled Wood: 1, Common Blue: 3, Marbled White: 4 Peter Gore
25 Jun Branch Event
Despite a dreadful forecast and overnight rain, the walk was extremely successful. We were joined by Dick, one of the Chorleywood transect walkers and three other members. Dick took us around the butterfly transect, which we helped him complete!!! Although cloudy the temperature was high and the grassland species were very active. In total we saw 1 Small Skipper, 1 Large Skipper, 4 Small Copper, 1 Brown Argus, 7 Common Blue including females trying to lay eggs on bedstraw, 10 Painted Lady, 1 Small Tortoiseshell, 1 Speckled Wood, 34 Marbled White, 161 Meadow Brown, 1 Small Heath, 1 Ringlet, 1 Silver Y and both a Cinnabar moth and caterpillars. Also seen through binoculars was a White-letter Hairstreak over some elm, ash and sycamore in a brief sunny moment

Most of the afternoon was spent in Bramfield woods where the following were seen. Red Admiral=4, Speckled Wood=4, Comma=1, Brown Argus=1, Painted Lady=8, White Admiral=1, Hummingbird Hawk-moth=1, Marbled White=2. Plus lots of Meadow Browns and Large Skippers.

24 Jun This morning 2 Painted Lady, 2 Red Admiral, 1 Small Tortoiseshell, 1 Meadow Brown, 1 Holly Blue and a Hummingbird Hawk-moth in my Ware garden Liz Goodyear
24 Jun After several early morning visits to Six Hills Common in the last week in search for close-up views of White-letter Hairstreaks it finally came good today with a specimen on elm about a foot above my head. Later, a pale-looking Burnet Companion was found in the field south of Watery Grove Peter Clarke
24 Jun Hounslow. A morning walk which began well with a White-letter Hairstreak seen on the Elms at the rear of Richmond Council's Hounslow Heath Open Space. The Elms here are suffering a little this year so as this is still the only group I know of in this tetrad I was pleased to see evidence that the colony is still with us. Much later a Marbled White on the opposite side of the trees was also very pleasing.In between came an Essex Skipper the first of its kind identified this year. Only the more or less guaranteed Gatekeeper to come of the established breeding butterflies here that I'm familiar with. Considering the destruction of the butterfly haven on the Marshalling Yards and the fires elsewhere we should probably consider ourselves lucky but of course sightings are well down generally. Here are today's and a simple game of spot the elephant: White-letter Hairstreak: 1, Painted Lady: 72, Meadow Brown: 78, Small Tortoiseshell: 1, Small Skipper: 4, Small Heath: 8, Red Admiral: 1, Essex Skipper: 1, Marbled White: 4, Small White: 2, Ringlet: 2. The weather was cloudy again with occasional spots of rain Peter Gore
24 Jun In Pymmes Park, Edmonton (TQ 336 929) from 12:30 - 13:40 hrs - 6+ Painted Lady including one nectaring on thistles, 5 Large Skipper including one female, 10+ Meadow Brown including a pair mating, 2 male Common Blue, 5 Small Skipper, 2 Comma together. 1 Painted Lady at Dalrymple Close, N14 at 17:10 hrs and Treble Brown Spot and Small Blood-vein after dark Robert Callf
24 Jun It was very warm and humid this morning at Stanwell Moor, but cloudy with odd spots of rain. Nevertheless, I saw nearly 100 butterflies in around 90 minutes, included no fewer than 16 Painted Ladies. There has clearly been an influx arriving with the humid airflow from the Continent.
The other standout sighting was of a Marbled White. This is only the second one I've seen here in over ten years of observation, and this time I managed to get a photo!
Finally, amongst a very small handful left of the first brood Brown Argus was this male with very much reduced underside spotting. I would like to have seen this one new!
Dave Miller
23 Jun At least 31 Meadow Brown, 1 Small Tortoiseshell, 1 Marbled White, 1 Common Blue - Purwell Meadows east, Hitchin (TL2029), 7 Meadow Brown - Purwell Meadows north, Hitchin (TL199300), 7 Meadow Brown, 1 Common Blue - Purwell Meadows west, Hitchin (TL1929) David Inward
23 Jun Hounslow. The number shown for Painted Ladies seen today is likely a significant undercount of the reality. I initially started out trying to avoid adding extra ones, assuming a lively single individual, then saw two together and thought that explained what I was seeing, then saw multiple numbers in several different places. At one point I was ignoring some to check out a Skipper which definitely had novelty value! More seemed to be arriving as I was returning across the heath so I'll be intrigued to see how many are still around tomorrow. The weather was rather gloomy so numbers of all species a pleasant surprise in the circumstances. Here are the full details: Comma: 8, Common Blue: 1, Large Skipper: 3, Red Admiral: 5, Small White: 3, Painted Lady: 18, Meadow Brown: 51, Small Heath: 5, Small Tortoiseshell: 2, Small Skipper: 6, plus one Box Tree and two Cinnabar moths Peter Gore

23 Jun A Dark Green Fritillary posed for a photo on some Viper's Bugloss on Therfield Heath this morning. I also noticed about 10 Marbled Whites and one Painted Lady Phil Barron
23 Jun Enjoyed a walk around Stapleford (based on the "Pub Walks in Hertfordshire" book). Over about 3 miles we saw over 100 Meadow Browns, 3 Common Blues, 1 Small Skipper, 1 Red Admiral, 1 Small White (and 3 other unidentified whites). The highlights were about 30 Meadow Browns nectaring on wild privet by the river and a colony of Peacock caterpillars Roger Newbold
23 Jun 1 Dwarf Cream Wave at Dalrymple Close, N14 this morning. Sightings in Oakwood Park (07:00 - 09:20 hrs) - 2 Painted Lady, 1 Cinnabar, female Large Skipper, male Small Skipper and 4 Marbled White Robert Callf
23 Jun 2 Marbled Whites on the meadow at Goldings, Waterford, this morning. At the corner near St Michael and all Angels church Christopher Benton
22 Jun Had a great morning out at Benfleet Downs in Essex photographing White Letter Hairstreaks one of my favourite butterfly sites. This evening I visited Tunnel Gardens in Bounds Green and was pleased to find two Red Admirals fighting each other for a sunny glade, two male Large Skippers, a Painted Lady and one Speckled Wood. I had been beginning to worry about the general absence of butterflies in Tunnel Gardens over the last week or so Miles Attenborough
22 Jun Purple Emperor seen at Totteridge Tony Clancy
22 Jun During a walk from Harlow to Ware to successfully fill in some gaps on the Meadow Brown map I found 4 fresh White-letter Hairstreaks nectaring on bramble along the track called Wood Lane, east of Ware. Otherwise a few Painted Lady, Red Admiral, up to 10 Small Tortoiseshells on one Privet hedge near Hunsdon. Other species seen were Holly Blue, Speckled Wood, Small White and Green-veined White Andrew Wood
22 Jun My firsts of the year at Alexandra Park. Marbled Whites into double figures, and also a few Ringlets in the anthill butterfly meadow area (TQ 299 899).
Small Skippers in the Meadow East of the Butterfly Meadow (TQ 299 900) and to the West of the Cricket pitch by the ditch (TQ 301 900).
I also found Peacock Caterpillars on nettles on the path leading to the conservation area by the wooden bridge (TQ 303 903)

20 Jun Hounslow. Too much cloud around but this was perhaps helpful in keeping a Small Skipper resting for long enough for me to get my first positive identification of the species this year. Minutes later a Large Skipper also obliged, a single glance being enough to confirm this only very slightly out of the expected sequence in the end. Here's the full list: Meadow Brown: 7, Holly Blue: 1, Speckled Wood: 1, Red Admiral: 2, Comma: 1, Small Tortoiseshell: 1, Small White: 1, Small Skipper: 2, Large Skipper: 1, Small Heath: 3, Painted Lady: 1. and one Cinnabar moth Peter Gore

19 Jun 1 Heart and Dart Agrotis exclamationis moth found apparently dead - St Faiths Close, Hitchin David Inward
19 Jun Humid, cloudy day until rain but saw my first Marbled White, as well as 15+ Meadow Brown, a Common Blue, a Large Skipper and 3 Cinnabar moths at Gutteridge Wood Pond Meadow (TQ093841) Paul Busby
19 Jun In Pymmes Park, Edmonton (TQ 336 929) this afternoon - 3 Meadow Brown, 1 male Large Skipper, 1 Yellow Shell and an Adonis' Ladybird Robert Callf
19 Jun This morning I saw my first ever Marbled White at Alexandra Palace (TQ299899) on the Anthill Meadow. Good numbers of Meadow Brown and Large Skipper were also on the wing. Small Tortoiseshell, Small Heath, Common Blue and Speckled Wood were also seen Gerry Rawcliffe
19 Jun St Albans - Small Tortoiseshell sunbathing in my garden at lunchtime. It's now 6 days since I saw the first new brood individual in the garden. None going into hibernation yet, but this could start to happen before the end of the month. A good time to clear cobwebs away from their favoured hibernation spots. Also a female Meadow Brown, a species that doesn't usually find my garden until late summer. But this year I have left most of the lawn uncut and I suspect it's the long grass which attracted it in Malcolm Hull
18 Jun Unclassified aberration of a Small Tortoiseshell at Bengeo. Blue spots on the forewing costal margin close to the thorax (see photo on right) Andrew Wood
18 Jun 8 species recorded on Southern Country Park transect including 20 Marbled White and a Painted Lady Bob Clift
18 Jun My first Marbled White of the year in the field south of Norton Green Common. Also about 30 Meadow Brown, 13 Large Skipper and a Small Heath Peter Clarke

18 Jun Hounslow. I managed to complete the outward journey this morning before the rain forced a quicker return. Sightings quite good in the circumstances: Small Heath: 3, Speckled Wood: 2, White-letter Hairstreak: 3, Meadow Brown: 3, Small Tortoiseshell: 3 Peter Gore
17 Jun Stocking Wood (13:00-14:30): No sign of either Hairstreak in their favoured locations yet. 1 Large White, 1 Small White, 1 Peacock, 1 Small Tortoiseshell, c.15 Meadow Brown, 1 Small Heath, 1 Essex Skipper, 1 Large Skipper Mike Harris
17 Jun A short walk on Therfield Heath (east of the clubhouse) revealed the following species: Large Skipper (1), Large White (1), Brown Argus (4), Common Blue (4), Marbled White (11), Meadow Brown (67), Small Heath (31). I couldn't find any Dark Green Fritillaries, but several Cinnabar moths were also seen Martin Johnson
17 Jun 1 Red Admiral, 1 Small White, 1 Brimstone - path by River Oughton, near Westmill Farm, Hitchin (TL170306), 3 Brimstone, 3 Speckled Wood - path by River Oughton, Oughtonhead Common, Hitchin (TL1630) David Inward
17 Jun Saw a White-letter Hairstreak high up in Elm canopy on Minet Country Park transect route, then at about 4pm, saw another relatively small specimen perched at head height on an Elm sapling, WLH's seen at both these locations last year (TQ 11 79). Other off transect records included a Common Blue, Brown Argus and Yellow Shell, Burnet Companion and Cinnabar moths Paul Busby
17 Jun Hounslow. With 15 species identified and at least one more flying, today's walk was a welcome change from recent weeks. The Elms were in full sun and I was not surprised to spot my first White-Letter Hairstreaks of the year. Not quite as easy to see a single Purple Hairstreak above perhaps the 27th Oak I peered at but later 2 Marbled Whites were seen in an area badly burnt last year were I feared they might have perished so particularly pleasing. My only frustration was failing to fully confirm Small Skipper. It was certainly bright orange and small but it decided to skip as I closed in on its antennae. A further sighting of another orange butterfly was less clear and I choose to think of it as a possible so far elusive Large Skipper but neither of these are included in the following list: White-letter Hairstreak: 3, Red Admiral: 2, Purple Hairstreak: 1, Comma: 1, Meadow Brown: 11, Small Heath: 10, Speckled Wood: 3, Brimstone: 1, Common Blue: 2, Marbled White: 2, Brown Argus: 1, Small Tortoiseshell: 1, Small White: 1, Large White: 1, Painted Lady: 1 Peter Gore
17 Jun At Trent Park - 1 Cinnabar near Oakwood entrance, 4 Common Blue 3 males & 1 female 'New Fields', also here 9 Small Heath and 1 male Small Skipper
At Monken Hadley Common - 4 Speckled Wood, 1 Holly Blue, 1 male Large Skipper (TQ 269 971), 1 male Small Skipper (TQ 269 972) and 4 Small Heath (TQ 267 973). 1 Small Tortoiseshell nectaring on Bramble blossom at Covert Way LNR (TQ 265 973) at 14:20 hrs. 1 Chimney Sweeper near Cockfosters entrance, Trent Park (TQ 280 967) and 1 Least Carpet at Oakwood Station - my first of the year
Robert Callf
16 Jun A fast-flying Dark Green Fritillary near the Therfield Heath car park (TL336400) Paddy Grove

16 Jun A few sightings whilst river sampling. Two Meadow Browns, Pinn Meadow, Ruislip (TQ 092 880), a Large White in Hillingdon by flowering bramble (TQ 086 843), Speckled Wood, 4 Meadow Brown, Silver Y and Burnet Companion moth in clearing in Cutthroat Wood, Hillingdon (TQ 08 84) and then Ickenham Fields by mainline rail (TQ 075 870), 10+ Meadow Browns and surprisingly my first Large Skipper of the year Paul Busby
16 Jun The Orchards, Sawbridgeworth (16:00-17:00): 1M Holly Blue, 3 Meadow Brown, 2 Ringlet Mike Harris
16 Jun Hillfield Park Reservoir, Aldenham - 3 Red Admiral, 15 Large Skipper, 6 Small Tortoiseshell, 1 Peacock, 2 Comma, 2 Common Blue, 1 Small Copper, 15 Meadow Brown Malcolm Hull
15 Jun A breezy but warmer and drier than recent days, saw 10+ Meadow Brown at Roxbourne Rough, Eastcote (TQ 120 876), then a Red Admiral at Broomfield Park, Palmers Green (TQ 304 928) and finally late afternoon saw another 20+ Meadow Brown, a Common Blue and a Burnet Companion moth at Wood Farm section of Stanmore Country Park (TQ 17 93) Paul Busby
15 Jun At my allotment in Muswell Hill (TQ 2890) I saw two Lime Hawk-moths on a Cherry tree, they were in no hurry. It is now raining, one wonders if they've moved Dee Cullen
15 Jun 1 Small Dusty Wave Idaea seriata moth - St Faiths Close, Hitchin (TL198303). Possibly the same individual as that seen on 29 May at almost same location David Inward
15 Jun My first White-letter Hairstreak of the year - at Six Hills Common in the canopy in the middle 'gap' at 9:40 am. While walking my Knebworth transects I again found several Chimney Sweeper moths at the same spot but this time I managed a decent photo! At Norton Green Common by which time it had completely clouded over I saw a Large Skipper posing nicely Peter Clarke
15 Jun Hounslow. A little morning sunshine although rain on the return journey led me to shorten the walk, the day's highlight was probably a Red Admiral on the Pevensey loop: Speckled Wood: 3, Meadow Brown: 4, Red Admiral: 1 Peter Gore
15 Jun 1 Red Admiral near Shaws Wood, Trent Park (TQ 297 970) at 14:56 hrs and 1 Common Carpet edge of Williams Wood near Dew Pond, Trent Park (TQ 294 973) Robert Callf
14 Jun Nice Painted Lady sunning itself in Hitchin garden this afternoon Martin Banthorpe
14 Jun 3 Marbled Whites and 8 Red Admirals reported on the Chorleywood Common transect Philip Gibbs
14 Jun 1 Red Admiral near Warbler Hide at Rye Meads RSPB this afternoon at 14:25 hrs Robert Callf
14 Jun A Hummingbird hawk-moth feeding on Red Valerian in my Stevenage garden this afternoon Peter Clarke
14 Jun In my garden in Flaunden (TL00A) this afternoon. Painted Lady, Red Admiral. Both butterflies looking freshly arrived or emerged Jill Saunders
14 Jun Chiswell Green - Gardens of the Rose - A Painted Lady on the public footpath this morning. Quite faded, it flew in short energetic bursts of flight along the nettles and thistles bordering the field in overcast conditions. Nearby a Red Admiral, 2 very fresh Large Skippers, 4 Meadow Browns, 1 fresh Small Tortoiseshell, Large Yellow Underwing and a Cinnabar moth. This pm in the HMWT Wildlife garden, St Albans, a fresh Painted Lady. WATCH OUT for more migrating Painted Ladies in the next few days Malcolm Hull
11 Jun Branch Event
Hillbrow LGC - Small Blue Walk. In spite of the overcast conditions with continuous light rain three people turned up, as they had come from some distance and expressed a wish to have a good look at the site we decided to proceed. At 11.10 we set off in rain, I had earlier found a roosting Small Blue which was relocated and observed up close. We later found a second roosting Small Blue and some Bee Orchids were photographed. We left the site at approximately 12.15 surprisingly satisfied, it was still raining!
Roger Millard
11 Jun Hounslow. Not much to report after yesterday's rain (some paddling necessary today) but I did manage to spot a Speckled Wood on the Heath and a lively Small Heath amongst the grass on the meadow side of the Pevensey loops. I confirmed my suspicions that the Richmond side of the Crane although accessible by the new bridge from Hounslow is not really suitable for a butterfly-seeking walk after rainfall. It was an enjoyable test of my geriatric long-jumping skills nevertheless and I did complete it without mishap Peter Gore
11 Jun 1 Speckled Wood near Shaws Wood at Trent Park at 11:58 hrs, 1 male Common Blue near Ride Wood, Trent Park, 2 Small Heath at Trent Park, 1 male Large Skipper along Leeging Beech Gutter at Vicarage Farm, Enfield (TQ 3097) at 13:52 hrs, also here 1 male Brown Argus and 1 Small Heath, 3 Small Tortoiseshell around 'Barracks' Vicarage Farm (TQ 3097). 3 Mother Shipton nectaring on Giant Hogweed along Leeging Beech Gutter at Vicarage Farm, Enfield (TQ 3097) at 13:50 hrs, 1 Yellow Shell at Vicarage Farm (TQ 3097) - my first of the year. 1 Garden Carpet at ASDA Southgate Robert Callf

9 Jun Whilst at Phasels Wood Scout campsite, saw 8 Meadow Brown and 6 Common Blue in the wildflower rich meadow adjacent to site car park (TL052042) Paul Busby
9 Jun Hillbrow, Letchworth G C - Small Blue x30+ (including mating pair), Common Blue 5m, Large Skipper x4, Large White x3, Small White x2 and Meadow Brown x50+. Day-flying moths included, Burnet Companion, Mother Shipton, Latticed Heath, Yellow Shell and Cinnabar Roger Millard
9 Jun Branch Event
Heartwood Forest, Sandridge, St Albans - 12 people joined Andrew Steele for the first Woodland Trust/Butterfly Conservation trip round this site looking for Small Blue. We had a good showing of day flying moths, enjoying the cool and sometimes overcast weather conditions. Burnet Companion, Mother Shipton, Latticed Heath, Yellow Shell, Cinnabar and Shaded Broad-Bar. Small Heath, Meadow Brown and Common Blue were the most common butterfly species with dozens of each seen.
Small Blues were also out in force, with a total of 16 recorded, mostly in the Valley Field alongside Wells/Puddler Wood, parts of which were seeded with Kidney Vetch in 2017. Other butterflies spotted were Small Tortoiseshell, Brimstone, Brown Argus, Speckled Wood, Large Skipper, Large White and Small Copper. Small Blues have been consistently recorded on this site in low numbers for the last five years. Today's total is the highest that has been recorded at this site by some margin

9 Jun Late morning visit to site off Hillbrow eventually proved successful. Had to wait 20 minutes for my first Small Blue here and then counted about ten more in less than half an hour on the bottom half of the slope. 30+ Meadow Brown, 2 Small Heath, a Small White and Large White plus Mother Shipton and Burnet Companion also seen Peter Clarke
9 Jun 1 Holly Blue - Triangle Community Gardens, Hitchin (TL19023021) David Inward
9 Jun Hounslow. Mid morning to mid afternoon with a mix of cloud and sunshine: Brown Argus: 3, Meadow Brown: 3, Speckled Wood: 3, Common Blue: 2, Small Tortoiseshell: 1, Small Heath: 5 and two Cinnabar moths Peter Gore
8 Jun White-letter Hairstreak in Durant's Park, Enfield Andrew Middleton
8 Jun 2 Burnet Companion, 1 Mother Shipton and 1 Meadow Brown at Oakwood Park (13:10 - 13:50 hrs) and 4 Speckled Wood and 1 Holly Blue at Boxer's Lake, Enfield (14:00 - 14:20 hrs) Robert Callf
7 Jun Not much flying today. A Cinnabar moth had wisely decided to take shelter from the rain inside my greenhouse Malcolm Hull
6 Jun I walked through Tunnel Gardens this evening at 6.00pm and was excited to find four Common Blue butterflies in the new meadow area we cleared last year, the first I have seen in the 12 years since we moved here. The birds-foot trefoil I seeded last year appears to have paid off. Two females and two males so hopefully more later in the year. Also one rather faded Holly Blue Miles Attenborough
6 Jun Therfield Heath (East side - Old Rifle Range): Large Skipper (1), Brimstone (5), Small/Green-veined White (11), Brown Argus (6, including a 'white spot' variant), Common Blue (11), Speckled Wood (1), Meadow Brown (6), Small Heath (28). Also 2+ Burnet Companion moths and a Broad-bodied Chaser dragonfly. Numbers of all species seem to be somewhat lower than at this time last year, perhaps at least partly due to the current virtual drought conditions in this area Martin Johnson
6 Jun Went to Broxbourne wood this morning, windy, sunny and cloudy, warm. Saw 2 Meadow Browns, my first for the year. Also lots of Speckled Yellow moths Kevin Standbridge
6 Jun Small Blue. Doing my survey of Kidney Vetch sites around the Baldock bypass today I finally, after many years, found one at the base of the shallow cutting where the B197 and the A505 diverge south east of Letchworth, just north of the drainage pond. Despite searching all the nearby areas I found no further examples, although the weather was alternating rapidly between sunny and dull and always breezy. This is 2km from the Hillbrow site. At Hillbrow the weather was similarly variable but I did see a number, the Kidney Vetch has spread in some areas and is holding its own despite scrub encroachment which I am assured will be dealt with this autumn. The set-aside field corner nearby has only a small amount of Kidney Vetch but, sheltered by a hedge and in a brief warm spell I counted 8 individuals, the most I've recorded at that site Andrew Wood
6 Jun Hounslow. A little surprised by how few butterflies I saw today, perhaps just a more noticeable 'gap' than last year: Holly Blue: 5, Peacock: 1, Speckled Wood: 1, Small Copper: 1, Small Heath: 1, Red Admiral: 1, Brown Argus: 1 Peter Gore
6 Jun A Painted Lady at Norton Green Common Sharon Chesterman
6 Jun At Rye Meads RSPB - 2 Red Admiral, 2 Brimstone male and female, Holly Blue, Speckled Wood Robert Callf
6 Jun I had a new visitor to my allotment in Muswell Hill (TQ282902) a lone Cinnabar Moth. My first ever sighting at that site. It explored my plot before settling for a while on the Beetroot Dee Cullen
5 Jun Hounslow. Another walk with very little sun getting through the clouds, I was pleased to see a lively fresh-looking Small Tortoiseshell on the heath towards the end of my walk.: Holly Blue: 1, Common Blue: 2, Small Heath: 3, Meadow Brown: 2, Brown Argus: 2, Small Tortoiseshell: 1 Peter Gore
5 Jun 1 Small Dusty Wave at bus-stop shelter at Chase Road/Charter Way, N14 and 1 male Common Swift at Bramley Parade, N14 (TQ 295 961). Found a beautifully fresh male Lime Hawk-moth at Oakwood Station near one of the lights (TQ 293 959) - the first live one that I have found, also 1 Treble-Brown Spot at bus-stop shelter at Enfield Road near Jolly Farmers PH. 10 Meadow Brown and 4 Small Heath at Vicarage Farm, Enfield (TQ 3097) this afternoon and 1 Burnet Companion at Parkside Farm/Res., Enfield (TQ 2998) Robert Callf

5 Jun At the Finch Lane Allotments: 1 Speckled Wood, 1 Small Copper and 4 Cinnabar moths Rebecca Palmer
5 Jun While walking the Knebworth transect I found 12 Chimney Sweeper moths at the same spot as last year in Knebworth Park (TL224211) Peter Clarke
3 Jun An unusual female Common Blue seen at Stanwell Moor on 28 May - see photo Dave Miller
3 Jun Saw a Small Skipper on Halsey Field Chris Ridley
3 Jun On unmanaged land (former quarry) between two arms of the M25 near Langleybury (Watford) (TQ0799): 17+ Small Heath, 3 Brown Argus, probably 3 Meadow Brown, male Brimstone, 1 Treble Bar (ID confirmed through photo of moth at rest), 13+ Cinnabar, 2 Mother Shipton, and 1 Yellow Shell. Elsewhere nearby a Red Admiral by the canal near Charlotte's Vale (TQ 088 981), and a Pale Prominent in one of two lit subways at Hunton Bridge (TQ 086 995) in which there were a total of 5 Common Swift Colin Everett
3 Jun Exciting to see a Hummingbird Hawk moth on Valerian mid afternoon in Kings Langley (TL069033) Elizabeth Debenham
3 Jun Hounslow. Just a few in rather cloudy conditions: Speckled Wood: 1, Common Blue: 5, Small Copper: 1, Brown Argus: 3, Small Heath: 1 Peter Gore
3 Jun Visited Woodcock Hill Cemetary, Rickmansworth briefly. Noticed 1 x Brown Argus and Cinnabar moths x 2 (TQ058 931) David Gower
3 Jun A good day at Rickneys - saw 3 Meadow Browns, first of the year. Many Small Heaths and 6 Common Blue
At Waterford Heath south - 8 Small Heath and a Holly Blue
In Broxbourne Woods saw first Large Skipper, in the glade and also Meadow Browns, 5 Small Heath and 5 Common Blue. Meadow Brown also in Bencroft Wood 3 and in field behind 5, in field behind additionally Small Heath 12 and six Common Blue. But many moths: Latticed Heath 6, Mother Shipton 4 and Burnet Companion 5

First Brown Argus of the year at Alexandra Park, by the NW corner of the cricket pitch
Dee Cullen
3 Jun At Trent Park - 5 Speckled Wood, 11 Small Heath 'New Fields', 5 Small Copper, 4 Common Blue - 3 males, 1 female at 'New Fields', 2 Large Skipper Sect 5 'New Fields' - my first of the year, and 4 male Meadow Brown here. 36 Chimney Sweeper at 'New Fields' Trent Park - a good count, also here 4 Cinnabar, 4 Alabonia geofrella near Church Wood (TQ 286 966), 1 Mother Shipton and 1 Buff-tip at Cedar House Financial Services, Bramley Parade, N14 (TQ 295 961). 3 Small Heath at Trent Park (1 near Water Garden, 2 'Old Golf Course'), 1 male Common Blue at 'Old Golf Course' Trent Park, 1 Small Tortoiseshell at Park Farm, Enfield (TQ 2998) at 14:46 hrs - my first of the summer brood, 3 Speckled Wood (1 near Shaws Wood, Trent Park, 2 at Park Farm, Enfield), 6 male Meadow Brown at Parkside Farm/Res., Enfield (TQ 2998), 5 Small Heath at Vicarage Farm, Enfield (TQ 3097), also here 1 male Common Blue, 1 Holly Blue at Enfield Rd/Jolly Farmers PH at 16:15 hrs Robert Callf

2 Jun Hounslow. Despite less sunshine much the same number of sightings today as yesterday with a modest highlight my first Meadow Brown of the year, two days earlier than last year's. Relatively small numbers but Brown Argus manages to top the list for sightings. They seem to have spread across the area and can be seen almost anywhere apart from the shady woodland stretches and the streets from home to the Heath. Speckled Wood: 7, Red Admiral: 1, Brown Argus: 9, Common Blue: 6, Small Copper: 2, Peacock: 1, Small White: 2, Brimstone: 2, Small Heath: 6, Holly Blue: 2, Meadow Brown: 1 Peter Gore
1 Jun Found a Purple Hairstreak at Tyttenhanger Gravel Pits by one of the old oak trees (TL191047) Andrew Steele
1 Jun Found 12 species on the Bishop's Stortford Country Park transect including my first Meadow Brown of the year. Watched a female Brimstone ovipositing on Alder Buckthorn whilst photographing Brimstone larvae on same plant - see photo Bob Clift
1 Jun I saw a Meadow Brown when walking the Bricket Wood Common transect. I was surprised my first sighting was a female; I'd expected the males to be out ready to approach the virgin females as soon as they emerged Chris Newton
1 Jun Holly Blue x 2 and Cinnabar moth x 1 in Bushey garden David Gower
1 Jun 4 Speckled Wood, 1 Brown Argus, 2 Orange-tip, 1 Green-veined White, 1 Small Tortoiseshell, 2 Silver-ground Carpet Moth (Xanthorhoe montanata) - Purwell Ninesprings HMWT nature reserve, Hitchin TL2029 David Inward
1 Jun St Albans - Spotted a female Brimstone flying along my street. She turned into my garden and headed straight for the Purging Buckthorn which she appeared to have detected from a distance of about 40 ft. Over the next 6 minutes she laid about 10 eggs, in each case selecting the newest tenderest growth. She explored several other bushes in the garden, but finding they were not Buckthorn then flew off. About an hour later she returned, still looking for suitable bushes, but she laid no more eggs on my Buckthorn. While searching for suitable laying locations she flew right round the bush, through it and underneath the leafy parts. The laying sites were all well separated, no two eggs laid together or even close to each other. All egg-laying sites were 6-12 ft above ground level - there were no lower leaves. I planted this bush over 15 years ago and never seen so many eggs laid on it. I pruned it quite heavily last November, which has produced a lot more new shoots than usual, which the butterfly seemed to like. I'd noticed the same with the Alder Buckthorn on my Allotment - a good winter pruning encourages more new shoots and Brimstone eggs. The female looked in pristine condition: considering she must have emerged from pupation last July that's quite impressive, not sure any other UK butterflies live for 11 months and still look good Malcolm Hull
1 Jun Hounslow. A lot of sunshine to start a new month but mostly 'old' butterflies with the possible exception of a bright, fresh-looking Comma to which I tried to get closer only to find myself sitting down abruptly amidst the Brambles and Nettles I was pushing through. They were evidently on a fairly steep decline. On these occasions it's the standing up again which can be most painful. Still, I managed it and the Comma was still fluttering around provocatively several feet in front of me. With the river just ahead I chose to remain unprovoked so I can only say it was probably a fresh new specimen. Here are the full sightings all less arduously seen and including a good day for Cinnabars; I don't pay proper attention to moths but one excuse so far this year has been that there are precious few to see anyway: Holly Blue: 4, Speckled Wood: 8, Brown Argus: 6, Green-veined White: 1, Brimstone: 4, Small Copper: 1, Small White: 1, Comma: 1, Common Blue: 10, Small Heath: 6, and seven Cinnabar moths Peter Gore
1 Jun Aldbury Nowers: 1 Green Hairstreak, 7 Small Heath, 3 Brimstone, 1 Holly Blue, 1 Common Blue, 2 Speckled Wood, 3 Orange-tip, 3 Meadow Brown and 1 Grizzled Skipper. Also 1 Burnet Companion Shailesh Patel
1 Jun In Oakwood Park this afternoon (12:45 - 14:10 hrs) - 1 Holly Blue, 2 Small Copper (male W of 10 km line, female E of 10 km line), 6+ Common Blue, 1 male Meadow Brown E of 10 km line - my first of the year. 2 Mother Shipton, 10 Burnet Companion (most E of 10 km line), 6 Orange Conch - Commophila aeneana - 1 W of 10 km line and 5 E of 10 km line - my first of the year, 1 Cinnabar E of 10 km line, 1 Pyrausta aurata at Conservation Pond W of 10 km line. 1 Riband Wave at ASDA Southgate Robert Callf


Date Description Recorder
31 May I saw a Meadow Brown on Chorleywood Common as part of our weekly transect survey. I saw it up close. Apparently this is very early for Hertfordshire. Certainly I haven't seen one thus early before. There may have also been a second but it wouldn't open its wings and I was not sure. But one was definite Philip Gibbs
31 May 1 Brimstone male - St Faiths Close, Hitchin David Inward
31 May 7 Brown Argus at Whitewebbs Farm, Enfield (TL 330 000), also here 2 Holly Blue and 1 Small Copper, 2 Brown Argus at Sloemans Farm, Enfield (TL 325 004). 1 Alabonia geofrella at Hilly Fields Park, Enfield (TQ 320 984) at 13:25 hrs, 3 Mother Shipton and 2 Cinnabar at Whitewebbs Farm, Enfield (TL 330 000) this afternoon Robert Callf
30 May Found a Light Brown Apple Moth Epiphyas postvittana (8-10mm) on my back lawn in Stevenage - a first! Peter Clarke
30 May A male Meadow Brown on Bricket Wood Common (TL 1307 0071) (my first ever May record for the species). Nearby a Small Copper at Garston Park LNR (TL 1223 0046) where sorrel is common on the hillside, and a Light Emerald moth in the lit subway (TL 124 006) between the two sites Colin Everett
30 May Hounslow. More sunshine than forecast encouraged butterflies to fly, including several more whites than I managed to identify. Here are the details: Common Blue: 4, Brown Argus: 4, Small White: 1, Holly Blue: 3, Small Heath: 1, Peacock: 1 and a Cinnabar moth Peter Gore
30 May At Vicarage Farm, Enfield (TQ 3097) (11:20 - 12:15 hrs) - 1 Green-veined White, 6 Small Heath, 1 Red Admiral near Allotments and 1 Burnet Companion. At Boxer's Lake, Enfield - 4 Speckled Wood, 3 Holly Blue and 1 Red Admiral. At Oakwood Park (13:35 - 14:35 hrs) - 10 Common Blue, 2 Burnet Companion E of 10 km line, 3 Mother Shipton E of 10 km line, 2 Holly Blue and 1 Speckled Wood Robert Callf
30 May Plenty in flight on my transect at Alexandra Park despite a strong breeze. Of note was a Burnet Companion new sighting for me at the park. By NW corner of cricket pitch (TQ300899) Dee Cullen
29 May This morning I was given escorted access by Network Rail to one of the Hertford area's Grizzled Skipper populations. Weather conditions were very unfavourable as there was sufficient sun to get a Grizzled to come off roost but not enough to make them fly actively. The visit was also quite late in the season? The Grizzled Skippers were simply basking on stones or soil - all very camouflaged! Only four were seen in total, three by the trackman Martin! Also seen were 1 Holly Blue, at least 14 Cinnabar, 2 Treble-bar moths, 2 Yellow Shell moths, 9 Small Heath, 6 Brown Argus, 1 Orange-tip and 1 Small Copper.
Last week Sharon Hearle reported seeing three Four-spotted Moths close to the Hertfordshire border and more sightings have since been reported in Cambridgeshire. Today I visited the site found by Sharon last week, close to the A505 - it is simply a recently dug ditch beside a minor road, which has ample food plant (field bindweed) and a brilliant nectar source of wild flowers. In total I recorded twelve of the moths - one was probably the most co-operative I have ever encountered. The weather conditions were very poor but they were still flying. I checked several other areas but by early afternoon the weather was getting worse so I can't say whether they weren't present or just not flying! Everyone interested in looking for this moth, needs to start looking now!

27 May I was at Hillbrow, Letchworth (TL 205 320) at around 4pm & am dead chuffed (life tick!) to have found a number of Small Blues (despite it being windy and not that sunny). I think I saw about 10 males that seemed to have found a bit of shelter from the wind (near a hedge towards the railway line). I noted some Kidney Vetch in the field, (not very much) & the butterflies were not particularly near to it Phil Barron
26 May 6 Small Heath and 1 Small White at Vicarage Farm, Enfield (TQ 3097), 2 Small Copper, male Orange-tip, 1 Peacock and 1 Mother Shipton at Parkside Farm/Res., Enfield (TQ 2998), 1 Alabonia geofrella at Vicarage Farm, Enfield (TQ 3097) at 12:06 hrs - my first of the year Robert Callf
26 May Branch Event
Greenwood Park, Chiswell Green - 30 people attended the launch of our new butterfly bank. After a short presentation, we walked across the park to the chalk bank site. Kidney Vetch seeds have been sown across nearly half the area and some Birdsfoot Trefoil planted. More planned on Friday, call me on 07768 154324 if you are free to help. The weather was overcast, but we saw a fresh Brown Argus, a female Orange-tip, Small Tortoiseshell caterpillars, Mother Shipton and Muslin moths. Earlier at the footpath off Chiswell Green Lane I saw a roosting Small Blue
Malcolm Hull

25 May My first Painted Lady of the year was on the Anthill Meadow at Alexandra Palace Park (TQ299899) this morning. Also seen were Red Admiral, Holly Blue, Common Blue, Small White, Speckled Wood, Small Copper and Brimstone. A local school hatched and released Painted Ladies late last week, so I think there is a reasonable chance that this morning's record is not a genuinely wild butterfly Gerry Rawcliffe
24 May Hillbrow, Letchworth G C - 13.15 to 14.30: Small Copper x1, Brimstone x3m & 1fm, Holly Blue x3, Brown Argus x1, Common Blue 6m, Peacock x1 (well worn) and Small Blue x8 (looked like all males) Roger Millard

23 May A Green Hairstreak reported from my parent's neighbour in their Highgate garden (Andrew Nield)
23 May Holly Blues in my St Albans garden, where it is a truly resident species. They spent most of the day flying round, nectaring and sunbathing. I saw one egg laying on the flower buds on the holly tree and disturbed another this evening which was roosting in the winter honeysuckle bush. A few weeks ago they were sunning themselves on the ivy hedge after hatching out from there. No other butterflies here today, but beautiful fresh female Broad-bodied Chaser hatched out of the pond Malcolm Hull
23 May Hounslow. Green Hairstreaks continuing to be spotted in small numbers well away from their usual local sites. Today's two included one settled on a bare patch of ground where it was very conspicuous, seeming more typical of a Small Copper or a Small Heath. Here are the full details: Holly Blue: 7, Green Hairstreak: 2, Speckled Wood: 7, Common Blue: 7, Small Heath: 6, Brimstone: 3, Brown Argus: 3, Peacock: 2, Small Copper: 3, Orange-tip: 1, two Cinnabar moths and one Mother Shipton Peter Gore

22 May Relatively low number of butterflies in the breezy sunshine but 13 species recorded whilst on transect walks in Hillingdon, including atypical Small Heath at Lake Farm, Hayes. Off transect records at Minet Country Park (TQ 109799) yielded a further 2 Small Heaths, a Brown Argus, male Common Blue, male Brimstone, Small Tortoiseshell, whilst by the Cycle Track (TQ 111803) saw a male Orange-tip, a Green-veined White and a Small White Paul Busby

I also saw a Mother Shipton moth on the top field of the site on my way home
Chris Ridley
21 May A couple of Holly Blues seen at the Community Wetland Planting Day at Broomfield Park, Palmers Green, Enfield Paul Busby
21 May Hillbrow, Letchworth G C, 11.45 to 14.00 - Orange-tip x2m, Holly Blue x9, Brown Argus x7, Common Blue x5m, Brimstone x2m & 6fm and Small Blue x1. Despite four recent visits this is the first Small Blue I have seen on this site, however another visitor I met said he had seen one earlier today on another part of the site Roger Millard
21 May I have seen only one Large White this year but I was amazed to find 3 clusters of yellow eggs 1-2 metres high on railings (facing east) surrounding a kissing gate by the Aston End Brook, south-east of Ridlins Wood, Stevenage. Are they really Large White eggs? I can't think what else they can be but I am happy to be corrected! The eggs have rounded peaks so not Large White! Peter Clarke
21 May Hounslow. Mostly sunny with a good selection of butterflies although Whites seem to be fairly poor at present: Holly Blue: 12, Peacock: 4, Speckled Wood: 4, Green-veined White: 1, Orange-tip: 3, Common Blue: 3, Small Copper: 4, Brown Argus: 4, Small Heath: 4, Small White: 1, Green Hairstreak: 3, Brimstone: 1 Peter Gore

20 May While out on my local patch at Stanwell Moor, I found my first Large Skipper of 2019 Dave Miller
20 May A single Speckled Wood in Cutthroat Wood, Hillingdon, looking back over the last couple of years, I am seeing less Speckled Woods this Spring at the usual woodland sites in Hillingdon, hopefully it will improve Paul Busby
20 May 1 Holly Blue - St Faiths Close, Hitchin David Inward

19 May Branch Event
We were joined by David Kirk, chairman of the Box Moor Trust and three other branch members for the walk around the lovely Bovingdon Brickworks managed by the Box Moor Trust. Overnight rain meant everything was a bit damp, and despite the forecast saying there would be some sunshine on arrival there was not. However, this proved a great bonus as it meant the resident Dingy Skippers were still roosting and a pre-walk search located several for everyone to see and take photos. A total of 6 were found in the meadow adjacent to the car park. As we set off it became apparent that the sun was trying to shine, which it did relatively weakly for the remainder of the walk. This meant that the Dingy Skippers were beginning to come off their overnight roosting seed heads but were as a result not flying very strongly or simply basking on the bare ground. A further 9 were found including a pair having quite a battle in the bottom of one of the pits. Also recorded were 3 Brown Argus, 3 Orange-tip, 2 Common Blue, and 2 Cinnabar moths. It was lovely to hear a cuckoo calling nearby and one more distant. Although the butterfly count was quite poor, everyone went home quite content with what they had seen.
Earlier we had made a visit to the A41 Bourne End slip road but were unsuccessful in finding any roosting Small Blue, however we did see 2 roosting Brown Argus and 2 Small Yellow Underwings. The Kidney Vetch though appears to be doing very well although not in flower yet

19 May Visited Coppetts Wood in Barnet between 9.45 and 10.30 in rather overcast conditions, only sighting were two Speckled Wood and 1 Holly Blue.
Walked along Tunnel Gardens from 11.00 till 1.00 photographing the flowers, some well camouflaged dock bugs on dock leaves and in the process I saw 5 Holly Blues, 3 Speckled Wood, three Green-veined White and was lucky enough to find a male Orange-tip who posed nicely on wild carrot and garlic mustard

19 May Small Tortoiseshell caterpillars spotted on the nettles on my St Albans Allotment. Most were in a series of clusters, with a few larger individuals beginning to disperse. Attempted a count, which was not easy and got to 300 individuals, which is more than I see at this spot most years. See video on Malcolm's twitter Malcolm Hull
18 May Off transect records for Minet Country Park, Hayes (TQ109800) - male Common Blue, Brown Argus, two female and one male Orange-tip and a Holly Blue Paul Busby

16 May I visited the northern part of Bedfont Lakes Country Park, and saw the following: Holly Blue 8, Brown Argus 6, Green-veined White 3, Common Blue 3, Green Hairstreak 3, Brimstone 2, Peacock 2, Orange-tip 2, Small Heath 1, Speckled Wood 1.
The Green Hairstreaks were widely separated, with the one shown in the photo being within sight of the visitor centre. The Common Blues included a beautiful blue female, more silver than blue
Dave Miller
16 May This afternoon we were walking round the Halsey Field in Gadebridge, Hemel Hempstead (TL042088) with some friends, when we had a really good view of a Green Hairstreak fluttering around, then landing on a Dogwood bush near the southern perimeter fence. Sightings of a Green Hairstreak were made this time last year on the site, so it looks very possible that the species is now breeding on the field. I didn't manage to get a good photo of the hairstreak as it was high in the bush, but I did manage a somewhat out of focus photo of the Small Yellow Underwing which I saw on Sunday 12th May at the bottom of the slope on Halsey field, as I was walking the transect Christine Ridley
16 May 1 Holly Blue female - St Faiths Close, Hitchin David Inward
16 May Hounslow. Cloud and breeziness reduced numbers a little but still plenty to see: Peacock: 5, Speckled Wood: 2, Green-veined White: 3, Common Blue: 1, Large White: 1, Orange-tip: 3, Holly Blue: 5, Small Heath: 4, Brimstone: 3, Small Tortoiseshell: 1, Brown Argus: 2, Small Copper: 1 Peter Gore

16 May The first Common Blue of the year - a female - was in the north west corner of the cricket pitches at Alexandra Palace (TQ300899) this morning, along with Brown Argus and Small Copper. Elsewhere on the Palace there were Brimstone, Holly Blue, Small White, Orange-tip and Peacock Gerry Rawcliffe
15 May At Water Lane , Watford found Orange-tip x 4, Brimstone x 2, Common Blue x 1, Common Carpet moth x 1. At Fishers Field afterwards seeing Brimstone x 3, Peacock x 2, Holly Blue x 1, Common Blue x 1 David Gower
15 May We went north and first visited Hexton Chalk Pit, arriving mid-morning so with the glorious sunshine everything was seriously on the wing! Immediately a small pyralid moth got our interest but we have yet to identify it. As we walked through the pit, it became obvious that there were serious numbers of Dingy Skipper flying - in some places one per square metre! It was impossible to get an accurate count but we reckon a minimum of 50 were seen. As we walked through the pit, we encountered a Green Hairstreak on the ground and then watching the various sycamore trees at the top end of the site we watched numerous duels and chases and at times they were interacting with the Holly Blue in the same area. Again they were hard to count but we think we probably saw about 9. Also seen during our visit were a single Small Heath, several Brimstones and on the adjacent field an Orange-tip. Day-flying moths included Small Purple Barred, Small Yellow Underwing, Pyrausta nigrata and aurata, and Burnet Companion.
We then went to Hillbrow at Letchworth but no Small Blue were encountered despite the Kidney Vetch appearing to be doing very well although nowhere near flowering. The majority of butterflies seen were either Orange-tip or Brimstones but we did see 2 Brown Argus as well as Holly Blues. Day-flying moths included Latticed Heath, Burnet Companion, Mother Shipton (photo), Cinnabar and Small Yellow Underwing.
Finally we visited a field opposite the entrance to the Wilbury Hill Carpark. Here butterflies were far more numerous with Brown Argus, Small Heath, Small Copper, Brimstones and Orange-tips flying. Day-flying moths included Latticed Heath and Small Yellow Underwing

15 May 1 Brimstone male, 1 Holly Blue, 1 Orange-tip male - St Faiths Close, Hitchin David Inward
15 May Oakwood Park (15:20 - 16:00 hrs) - 1 male Brimstone, 3 Holly Blue and 1 Small Copper and 10+ Mother Shipton were very active & restless. 1 Small White and 1 Holly Blue at Prince George Ave., N14 (TQ 299 956) at 16:05 hrs and 1 Peacock settled at Boxer's Lake, Enfield at 16:15 hrs Robert Callf
15 May Hounslow. Two Small Heaths completed our local list of spring butterfly species (17) on another sunny day. One other highlight and one oddity: a Green Hairstreak on one of the burnt areas moved purposefully from one little patch of regenerating Bramble to another.I didn't manage to spot any eggs or actual laying but it did look as though that was what the butterfly had in mind. What two butterflies seen shortly after had in mind was something else altogether, a Small Tortoiseshell and a Peacock spent quite a bit of time together in a manner most unlike these two species. Although never actually mating, at one point they were both on my left foot -a double first for my left foot there and a little later the presumed male Small Tortoiseshell was resting at right angles on the closed wings of the Peacock. I left them to it, whatever 'it' was! Here are the full details of sightings: Holly Blue: 9, Speckled Wood: 1, Green-veined White: 2, Small Copper: 5, Brimstone: 5, Common Blue: 1, Comma: 1, Red Admiral: 1, Orange-tip: 9, Peacock: 5, Green Hairstreak: 2, Small Heath: 2, Brown Argus: 1, Small Tortoiseshell: 1, Large White: 1 Peter Gore
14 May Seen in Bushey garden: Holly Blue x 5, Peacock x 1, Comma x 1 David Gower
14 May This afternoon in my St Albans garden - Orange-tip, Green-veined White, Brimstone, Holly Blue, Mint moth and longhorn moth Malcolm Hull
14 May A probable Large Tortoiseshell or Scarce Tortoiseshell just N of Bovingdon at lunchtime. I flushed the butterfly next to a footpath and was struck by its size (similar to Painted Lady) and colour (pale orange-brown); when I very briefly glimpsed the markings it was obviously a tortoiseshell but the flight was very different - strong with frequent glides, like a large fritillary. It was also very skittish and I could not relocate it once it had flown off into an adjacent field. The location was the footpath between Duckhall Farm and Bourne End Lane near the karting track, where the path changes from a NE to NNW direction and a grassy field opens out on the east side, about 20 metres N of the end of the hedgerow, at grid reference TL 01418 04468. I'd welcome any attempts by other observers to re-find it. Nearby there was a Small Copper at the entrance to Little Hay Golf Course (TL 0192 0465) Colin Everett
14 May Alexandra Palace's (TQ303898) first Brown Argus of the year was found in the south east corner of the park, somewhat away from where it was expected! Also Small Copper, Orange-tip, Brimstone, Speckled Wood, Holly Blue, Peacock, Small White and Green-veined White seen but surprisingly no Small Heath which have been a feature in recent days Gerry Rawcliffe
14 May 1 Brimstone - St Faiths Close, Hitchin David Inward

11 May Spring Meadow Farm, White Hill Lane, Whelpley Hill, near Bovingdon - 4 Dingy Skippers in this 8 acre wildflower meadow, created from a former potato field. The Dingy Skippers were in two courting couples, which spent ages flying close together twiddling round each other. Luckily one eventually landed for a photo. Also in the meadow were Orange-tips, Green-veined Whites, Peacocks, a Brimstone and a Small Tortoiseshell. Lindsay McRae also saw a Small Copper.
This farm straddles the Herts/Bucks border and while the buildings are all in Bucks, the 8 acre wildflower meadow is all in Herts. Note it is a private site, the landowner will allow access by prior arrangement, contact me for details.
A41 Bourne End junction - stopped at this Small Blue site on the way home, but no sign that they have yet emerged at this location

8 May This was our first opportunity to look for Grizzled Skippers and the 'damp' weather didn't deter us, even the thunder and lightning didn't stop us although a very soggy notebook was a bit of a nuisance.
We started at Frogmore just after 10.30, it was raining and the temperature didn't go much above 10 °C. In total we found exactly 10 roosting Grizzled Skipper distributed throughout the site. We believe 7 were male and 3 female with a choice of seed head being Perforate St. John's Wort (3), Knapweed (4), Bramble (2) and one unidentified stem! We looked at the hawthorn and flowering Forget-me-not but there really was too much to check. No eggs were found but with the wet weather and rain drops looking like eggs it wasn't the right day to start looking. Also found roosting were 8 Brown Argus, 1 Small Copper and 1 Toadflax Brocade moth. We finished just after 12.30.
We then went to Rickneys Quarry and started walking around the site at 1.20 and although there were moments of brightness which made at least one Grizzled Skipper open its wings, the majority of the afternoon was spent walking around in the rain. Just at the end the sun came out and some of the Grizzled Skippers became active but we couldn't count these. We left around 4.30 just before a torrential downpour. Totals here were 12 Grizzled Skipper, with we believe 7 males and 3 females and the remainder not confirmed. Here the seed-heads being used were Carline Thistle (4), Bramble (4), Perforate St. John's Wort (3) and one further individual on the move. Also recorded were 6 Cinnabar Moths, 1 Latticed Heath moth, 2 Small Copper and 21 Brown Argus. Also noted was a Pyrausta species of moth. We did not record any roosting Small Heath which we expected to do.
We also looked at one of our favourite elm trees with really low easy to check branches. On inspection and only during a matter of minutes and below head-height we counted at least 13 White-letter Hairstreak caterpillars, all now on the leaves and only one more mature with one also we thought was predated. There were several other caterpillars and a lot of larval damage on the elm. We hope to identify the caterpillars in due course

1 May This morning, I visited Bedfont Lakes Country Park. I started at the southern, less well-known section, and in within a few yards of entering the main part of the park I had seen my first Green Hairstreak down on the grass. By the time I left, I had seen seven altogether: four in this area, one close to the railway, and two more on the far side of the lake. They must be spread across the whole site. Also seen: Holly Blues (9), Speckled Woods (8), and Peacocks (2).
There being no link between the two sections, I drove round to the northern part of the park, and found two more Green Hairstreaks close to the railway. The sun was getting very hazy, and the only other sightings were: Holly Blue (1), Peacock (2), and Green-veined White (4).
Returning home, with the sunshine getting stronger again, I walked my usual circuit at Stanwell Moor. Holly Blues were everywhere, as they have been for a while now - 23 seen. There were also Orange-tips (8), Brimstones (4), Peacocks (2), Green-veined White (7), and Small White (1). I also found a shiny new Small Copper (my second here this year), and more of a surprise, a new male Brown Argus. This was my first of the year anywhere

29 Mar Two separate male Orange-tips: one at Aldbury Nowers (SP 957 135) and one at Berkhamsted Common (TL 005 093). For comparison, back in 1995 a male I saw on 3rd April was the earliest ever for the county in what was then a remarkably early spring; multiple March sightings (as this year) would have been unthinkable even a few years ago.

One of the ST's had not gone far and was found flying around inside my car parked close by. Another was found dead, shrouded in spiders web. Later in Greenwood Park there were many Peacocks, Small Tortoiseshells and Brimstone in flight. Finalised arrangements for the construction of the chalk bank, hopefully we will see Small Blues in this location within a few years Malcolm Hull

25 Mar I walked my WCBS in Northaw Great Wood early afternoon and saw three Commas. Two were scuffling high up and eventually landed to sunbathe. The third in a different area was basking in a sunny spot Dee Cullen
25 Mar On another tour of my local patch at Stanwell Moor at near enough the same time as on the 24th and in similar conditions, my first two sightings were of new species for the year. First came a Holly Blue flying around ivy near the River Colne, followed immediately by an Orange-tip sunning itself near the river bank. This was disturbed by a Red Admiral, which then basked on the bridge over the river. Overall, in addition I saw another Holly Blue, plus four Small Tortoiseshells and eight Peacocks, including a pair courting high up in a flowering prunus Dave Miller
25 Mar 1 Small Tortoiseshell resting on stinging nettles by the Colne Rebecca Palmer

All were males and were seen between 10:20 and 14:20 hours Colin Everett
24 Mar A warmer than forecast, sunny Spring day and decided to visit Hillingdon transects, where I saw 20+ butterflies, Peacocks accounted for half of them with some Small Tortoiseshells, Commas, male Brimstones and my first Holly Blue of the year in the small copse at Lake Farm Country Park. I think it shows the value of starting the transect early if conditions are within limits Paul Busby
24 Mar 1 Brimstone - Meadowbank, Hitchin (TL196300), 1 Brimstone - Railway Station, Hitchin (TL194297) (possibly the same individual) David Inward
24 Mar An early afternoon walk in Fairlands Valley Park and the surrounding woods resulted in 36 butterflies: 11 Brimstone, 15 Peacock, 6 Comma, 2 Small Tortoiseshell and 2 Small White. The Peacocks and Small Whites were my firsts of the year Peter Clarke
24 Mar Hounslow: Ideal spring weather for butterflies so not surprising to find numbers of sightings well into double figures. These included our first Orange-tip of the year, one day earlier than 2017's early sighting. Here are the details: Brimstone: 8 Comma: 4 Peacock: 6 Orange-tip: 1 Small Tortoiseshell: 1.

17 Mar I found quite a few Purple Hairstreak eggs on Oak buds in Northaw Great Wood (TL2804). I saw adults last summer there while doing the WCBS count so figured it was worth having a look Dee Cullen

9 Mar First time I have ever seen a Camberwell Beauty - at Winchmore Hill Station at 1205. (Filomena Jones reported a sighting at Finchley Central N3 in February - unsure of exact date. Could it be the same specimen being about 5 miles away? Peter C) Robert Bourton

1 Mar St Albans Shed - Pleased to report that today's shed transect produced a full complement of 13 Small Tortoiseshells and 3 Peacocks. None have been seduced out of hibernation by the warm February weather. Judging by the miserable forecasts for the next two weeks, they have been wise to stay asleep indoors Malcolm Hull

25 Feb Brimstone at Waterfields Playground, Watford. Small Tortoiseshell and Red Admiral in Park Avenue, Bushey Rebecca Palmer
25 Feb Hounslow: More sunshine and more Brimstones. I've slightly reduced the number of actual sightings to allow for the possibility of highly active males (which they all are) getting counted twice so it's Brimstone: 7 Small Tortoiseshell: 1 Peter Gore
25 Feb Hertfordshire County Offices car park adjacent to Grand Union Canal at Apsley (TL066047) - 3 Brimstone Robert Harris
25 Feb A female Brimstone, a Comma and at least two Red Admiral and two Small Tortoiseshell seen at Alexandra Park (TQ302902) Gerry Rawcliffe
25 Feb One male Brimstone in my south Harpenden garden David Hunt
25 Feb Another wander round my local patch at Stanwell Moor a bit earlier in the day. Three Small Tortoiseshells, only one of which was one of those seen yesterday. Only a couple of Brimstones (delayed by the overnight low temperatures I suspect), but today's new arrival was a newly-emerged male Small White. This is the earliest I have seen one Dave Miller
24 Feb Brimstone in Ruislip (TQ097867) Catherine Hookway

24 Feb Folly Lane St Albans - My first sightings of Small Tortoiseshells in flight this year. I saw one courting couple, a third nectaring and a fourth sunbathing. At this site, the hibernators usually rely on Dandelions as their main nectar source after emergence. At present there's not a single Dandelion flowering on the whole site and very little alternative nectar sources, which is a source of concern. One male Brimstone also and reports of a female seen on the same site earlier. Worth mentioning also that I saw a Small White flying yesterday on a visit to South London - outside our Branch area, but worth keeping an eye out for an early emergence of white species over the coming week Malcolm Hull
24 Feb Brimstone at St Paul's Walden (TL192222) and at Rookery Wood, King's Walden (TL166232). Small Tortoiseshell at Chalkleys Wood, St Paul's Walden (TL185226) Martin Ketcher
24 Feb Was out in the early afternoon and though I saw half a dozen Brimstones, they had all disappeared by two o'clock. However, this was compensated by the presence of three Commas and three Small Tortoiseshells.
On top of this was the very unusual sighting of a Hummingbird Hawk-Moth. I see few of these here even in the summer, so one in February was a real surprise. I assume it to have been a migrant from southern Europe

Date Description Recorder
30 Jan Andrew and I decided to return to Ickenham and visit the fields first to the south of the site. We started just before 9.30 and finished searching at 3.40 - so about 6 hours x 2 = 12 hours!
We first visited the field where Andrew found the 2 Brown Hairstreak eggs last summer and found 2 more but one was 5 feet up on a twig. Another egg later in the day was 6 feet up. We couldn't re-find the summer eggs and it looked like they might have been cut down as there was a lot of brash on the ground where the mower had been in quite close. Having found 2 eggs we didn't search too much of the blackthorn. We walked up the track and then found an egg in the corner but didn't find any more eggs along that particular hedge line. We crossed the fields and walked to the other side where there are some oaks. We found an egg in a small area of scrubbed up grassland close to the railway. We then retraced back to the main fields and followed the hedge line towards our other adult sightings last summer where we found a further 21 (twenty one) eggs. Making a total of 25 in total and 12 Blue-bordered Carpet moths and a cluster of 16-spot ladybirds. One twig had 2 eggs together - a first for us!

22 Jan 1 Red Admiral feeding on Viburnum in the sunshine, this lunchtime in Harlington Andrew Wood
18 Jan In spite of the very cold morning I found one Red Admiral butterfly in my Chorleywood garden. It had its wings closed and was very chilly so I brought it indoors and within 10 minutes it had thawed out and alive enough to set free. It escaped over the rooftops hopefully to live another day Irene Oulsnam
16 Jan Neither Andrew or myself had ever visited Horsenden Hill so despite two egg searches there this year, we couldn't resist visiting. We didn't pick a very nice day and got pretty wet.
We parked opposite the Ballot Box Pub just before 11 and walked the fields close to the road - the blackthorn is seriously impressive and in some places very good but a lot had reddish stems. In our searches today we found 19 Blue-bordered Carpet eggs which always pleases us.
As it got damper and after about 2 ¼ hrs searching (x 2) we started walking towards the infamous Paradise Fields not far from the Canal walk, there was some 'black stemmed' blackthorn. The blackthorn was close to some oak and two slightly greenish Brown Hairstreak eggs were found close together on a single twig. No more eggs were found (nor BBC eggs) but it was getting even wetter and enthusiasm was waning. We did look at Paradise Fields but all the blackthorn was red stemmed. We got back to the car around 2.30
