22 May 10 Small Heath including three together at Vicarage Farm, Enfield (TQ3097), 1 Brown Silver-line flushed from bracken SW edge of Rough Lot, Trent Park Robert Callf
22 May Millhoppers Reserve - Walked over this afternoon not expecting too much with the blustery conditions. 1 Green-veined White, 1 Small White and 2 Speckled Wood near the entrance. But in the top pasture dancing around within the long grasses were 2 Common Blue and 2 Brown Argus. 14 species this year so far on the site Chris Hilling
21 May I showed Tanya, the new ranger for Bricket Wood Common (and Nomansland Common), the route of the Bricket Wood Common transect. On our way round I spotted and photographed a Small Heath (TL131007; only 19 have been recorded during the transect from 1997 onwards, and 12 of those were in 2013, with 4 last year. I hope seeing one today is a sign I'll see some to record for the transect, and that the cattle grazing over the last few years is improving the site for these butterflies

19 May In the garden Wareside - The Brimstones are still very active egg laying on the buckthorn, whist Orange-tips are still finding vacant hedge mustard to lay more eggs, although there are quite a few caterpillars now. Holly Blues are frequent visitors and been seen laying eggs on dogwood flower buds. We have had them on the berries before but not the flower buds. Several other "unidentified whites".

19 May St Albans - this evening I disturbed a female Brimstone, roosting underneath the raspberry canes on my allotment. She was perched in low vegetation about 3 inches off the ground. She quickly settled back into the same position after being accidentally watered. I think she may have been keen to stay in this spot as the raspberries are right next to my Alder Buckthorns

Brimstone St Albans 19 May

19 May Hounslow. Despite high temperatures and plenty of sun here we seem to have arrived at something like a mid-season lull as far as numbers of butterflies are concerned: Holly Blue: 3, Green-veined White: 1, Peacock: 2, Speckled Wood: 1, Brimstone: 2, Common Blue: 1, Small Heath: 4, Orange-tip: 2 Peter Gore
19 May I found and photographed a Small Blue on the chalk bank at Butterfield LNR in Wheathampstead. There is a small patch of Kidney Vetch there, but not much. This individual may have come from the Heartwood colony. I also saw the first Common Blue for this year

19 May 2 Small White - St Faiths Close south, Hitchin (TL198302) David Inward
19 May A long LEW which took in TL3614, TL3814 and TL3816 proved to be very hot but productive in finding Small Heath. 5 completely new sites were found in areas almost void of records in the past years (to my knowledge). Three were fields where they were visible through binoculars and the last find was an small area of derelict grassland just 150m (as the butterfly flies) from my Ware garden. A total of 14 adults seen. Failed to find Holly Blue in TL3816 but numerous fast flying unidentifiable whites. Orange-tips and Brimstones were still out in force including an egg laying Brimstone female in our garden. Also near to home a few Peacocks and a Small Tortoiseshell Liz Goodyear
19 May Cycled along Ebury Way adjacent to Croxley Green moor (TQ 095947) where I saw 4 Small Copper & 1 Peacock. At Woodcock Hill Cemetery, Rickmansworth (TQ 058931) were 2 Common Blue, 1 Brown Argus, 1 Cinnabar moth & 1 Burnet Companion David Gower

16 May We were walking in the fields near Little Gaddesden near Hemel and noticed the farmer had left a field margin for wild flowers and grasses. Sunbathing amongst the grasses was this Burnet Companion. We also saw Orange-tips nearer the river and Small Whites fluttering around the hedges and over the meadows

15 May St Albans. White species dominated on my stroll along the Ver Valley towards Redbourn this afternoon. Green-veined Whites dominated, followed by Orange-tips, with several Large Whites, a Small White and a Brimstone. Numbers of other butterflies seem to have dropped during a week where we have had three frosts. The only other butterfly sightings were 2 Peacocks and 1 Small Tortoiseshell. The star of the day was a Muslin Moth, which stopped obligingly for a photo

Dacorum's new policy is to leave more patches of grass unmown during the summer months, which is a big improvement on the uniform short turf of previous years

Mother Shipton Gadebridge Park 9 May

7 May 1 Small White, 1 Large White, 4 Orange-tip, 4 Holly Blue - Walsworth Common, Hitchin (TL1930) David Inward
6 May Hounslow. An enjoyable strenuous walk in the sun brought the reward of two more year firsts.The initial bright blue butterfly wasn't quite good enough to claim for Common Blue given the presence of Holly Blue in the same area but a later one which settled justified both. Later still a similar pattern developed with Green Hairstreak but here the rapidly flying suspects really weren't clear enough whilst one which settled was every bit as green as the Common Blues had been blue, to leave no doubt. A good variety overall with Orange-tips surprisingly elusive whilst other whites were perhaps commoner but too active to identify many: Holly Blue: 8, Green-veined White: 4, Peacock: 21, Speckled Wood: 4, Comma: 2, Brimstone: 5, Small Heath: 2, Small White: 1, Common Blue: 2, Orange-tip: 3, Small Tortoiseshell: 2, Small Copper: 1, Green Hairstreak: 1. Yesterday a Red Admiral joined the obligatory 2 Holly Blues in my garden where some fresh holly leaf-tips are being consumed by unseen eaters Peter Gore

6 May I took my exercise walk around Shrubhill Common in Hemel Hempstead (TL036072). I was very pleased to see two Dingy Skippers - the first I've seen there since 2017. They are easily overlooked at this site, unless they happen to land on the path in front of you. Fortunately this is what happened Roger Prue

Date Description Recorder
29 Apr Jane and I had our exercise walk early as the weather was perfect for spotting Grizzled Skippers roosting on seed heads at Waterford Heath. I was cursing when the sun came out - how perverse. However on the south Heath we found 7 on the east bank, 3 towards the northern end , 1 on the Black Barns site and 2 along the ditch that runs along the centre of the bowl. All but a couple were in quite sheltered positions. None in the settling beds. On the north Heath only 2 both on the east side. A total of 15. Also one Treble Bar and one Latticed Heath moth and many Roman Snails enjoying the better conditions for them

22 Apr Having seen the pristine male Orange-tip roost in bright windy sunshine in Tunnel Gardens late last night I could not resist getting up early and seeing if I could get a better shot of him with my tripod in the more shaded early morning light with less wind. Pleasingly at 7.00 this morning he was still there and I got the shot I hoped for although still annoyingly windy even at that time. On my way back an hour later I saw three Speckled Woods basking in sunny glades

10 Apr On my walk I saw my first Speckled Wood of the year, on Section 4 of the Bricket Wood Common butterfly transect, where the path runs parallel to the 'Gas Ride'. This butterfly stayed in the area long enough for me to get a photo (it won't win any prizes, but it's good enough for identification). Also, as is currently usual, lots of Peacocks, some Brimstones, male and probably female Orange-tips, Commas and Small Tortoiseshells on my walk

10 Apr St Albans - no hibernating Peacocks or Small Tortoiseshells in my shed today. The last 23 all left this week. At the nearby nettlebeds in New England St I found 7 Small Tortoiseshells and no Peacocks. At Folly Lane, 6 Small Tortoiseshells and 4 Peacocks, also 8 Orange-tips, 2 Brimstone, 2 Holly Blues and 1 Small White. None of the butterflies I saw were nectaring and the dry weather may have caused nectar to dry up. So I have decided to water my dandelions to help the butterflies find food Malcolm Hull
9 Apr On my walk I saw what I believe was a Light Orange Underwing moth, fairly early on Section 2 of the Bricket Wood Common butterfly transect, where the path runs parallel to the 'Gas Ride'. I saw it settle on the ground, and could clearly see orange close to its body, with grey-brown forewings with some faint banding running across their length. It seemed settled on the ground, so I took off my camera bag, got out the camera and mounted the macro lens, but it had disappeared. It reappeared, and the third time it settled I got as far as focusing on it before it flew again, and this time it flew away. It looked slightly smaller than I remember one I saw 5 years ago that Malcolm Hull deduced was a Light Orange Underwing.
Also lots of Peacocks, some Brimstones, male and probably female Orange-tips, Commas and Small Tortoiseshells on Bricket Wood Common and elsewhere on my walk

8 Apr I took my LEW around the footpaths north of Ware much later in the afternoon in the hope that an Emperor moth would come to my lure. Peacocks (15) and Small Tortoiseshells (11) were abundant although mostly in the first ditch I walk past. Nothing came to the lure so when I got back to my Ware garden at 5.30 I put the container on my washing line and within minutes this absolute stunner of an Emperor moth arrived. I knew it wasn't the same as the previous day as it was pristine!

7 Apr LEW took me across the paths north of Ware to Cold Christmas and back. Lots of butterflies seen including Brimstone, Orange-tip, 15 Peacock, 9 Small Tortoiseshell and 1 Small White. I deliberately went in the morning when activity was heightening but it was just at the end of the walk where passing a bit of derelict grassland near the back of my road that most activity was observed. Here there were male and female Brimstone and Orange Tip, all be chased by each other! However it wasn't until 4.25 in the afternoon that the star of the show arrived in my garden - a male Emperor moth to lure

7 Apr I saw my first Holly Blue and Orange-tip of the season in our Hemel Hempstead garden. The orange was extremely vivid, so I suspect the Orange tip had just crawled out of its pupa. A Small Tortoiseshell also made a brief appearance Chris Ridley
7 Apr I saw a male Orange-tip along the part of the 'Gas Ride' on Bricket Wood Common included in the transect (TL1301), along with a male Brimstone and about a dozen Peacocks along that part of my walk alone. My first orange tip of the year, although I reported that my wife had seen a couple on 5 April. I don't remember ever seeing so many Peacocks about in spring before; it's a pity we aren't walking formal transects to record them objectively Chris Newman
7 Apr Back to Merryhill via Bushey Manor field spotting 2 x Peacocks. At St James churchyard were 2 x Orange-tips (m & f), Comma x 1, Peacock x 3, Small Tortoiseshell x 1. Lastly at Merryhill fields were Peacock x 9, Brimstone (m) x 1, Comma x 4

7 Apr Saw my first male Orange-tip of the year as I started my daily exercise walk up Barnhill. It was still in the same area on my return and got 1 decent shot while it nectared briefly. Most of my walk was devoid of butterflies (too hot???) but I did count 5 Brimstones, 1 Small Tortoiseshell, 1 Comma, 9 Peacocks, 2 unknown whites (I suspect one might have been female Orange-tip and one Green-veined white but uncertain) and my first 2 Speckled Woods of the year

3 Apr Despite some nice sunshine I didn't record any butterflies on my LEW this afternoon around the fields north of Ware. However, overnight I recorded a Blossom Underwing. This is a new garden record and not at all common in Hertfordshire. Photos also of a Streamer and Dotted Chestnut - both new for the year in my Ware garden

3 Apr St Albans shed - 17 hibernating Small Tortoiseshells and 6 Peacocks. That's exactly the same numbers as this time last week. So during a cold week when we had frost and ice on the pond no butterflies left hibernation. A big contrast to the previous sunnier week when one third of the total number of hibernators departed. Interesting that none of the previous weeks departed returned - hopefully they found shelter from the cold elsewhere Malcolm Hull
2 Apr Stanwell Moor: Brimstone 2, Peacock 2, Comma 1, Small White 1. Only a brief burst of sun, though it was warmer than the previous few days Dave Miller

31 Mar Millhoppers Reserve - Much cooler but the hedge/tree line kept most of the breeze out so pleasant when the sun broke through. The water level has dropped considerably since 22nd when Malcolm saw it ... maybe 5 inches.

28 Mar Stanwell Moor: Sunny first thing, but the northeasterly breeze was picking up markedly and bringing extensive cloud with it. My usual walk produced only three brave butterflies: Comma 2, Peacock 1 Dave Miller
27 Mar Stanwell Moor: Another very similar day, but the first butterfly seen today was a fairly cooperative Small White nectaring on dandelions.
Further on along my usual circuit, I spotted a Brimstone basking (sideways on of course!), and then a Comma nearby. Trying to decide which to concentrate on, I was disturbed by another butterfly fluttering across in front of me. This turned out to be an Orange Tip. After settling at a distance, it briefly sat quite close by. I ended up seeing one more later on, amongst a total of at least 30 individual butterflies on the day. Peacock 12, Comma 10, Brimstone 5, Small White 2, Orange-tip 2, Small Tortoiseshell 1

27 Mar On my local exercise walk north of Ware I saw 4 Small Tortoiseshell and 2 Peacock but again no Brimstone. I took my Emperor moth lure but despite other Hertfordshire reports, nothing was attracted to it. Also heard and saw a Yellowhammer which was rather nice. On the map part of my walk passes an area marked Common but access was behind a 12 foot deer fence but I have now found a public footpath that goes through it. Hopefully it will produce some nice butterflies over the spring and summer for me to see during difficult period Liz Goodyear
27 Mar Millhoppers Reserve - one Comma and four Small Tortoiseshell and just one human ... me! Glorious isolation Chris Hilling
27 Mar New England St Playingfield, St Albans - 3 Small Tortoiseshells in the afternoon sun at the nettlebeds close to my house. A male intercepted a female in flight and they landed on the fed flowerhead of a Buddleia. But she was unreceptive and after 2 minutes he flew off, leaving her to self isolate

27 Mar St Albans Shed - 17 Small Tortoiseshells and 6 Peacocks still in hibernation today. So that means that around 50% of each species has now emerged. That's up from below 20% this time last week - not surprising given the prolonged period of sunny weather. Yesterday I saw one of both species on the wing in the garden. I also found two very soporific Small Tortoiseshells on the back door mat. It seems to take a lot of effort to bring them back to life - these two appeared to have crawled out of the shed under the door! Malcolm Hull
26 Mar Stanwell Moor: Despite continuing quite warm sunshine, no more Small Whites or Orange Tips appeared today, but the Peacocks and Commas were out in force, along with a few Brimstones and Small Tortoiseshells. Peacock 10, Comma 9, Brimstone 4, Small Tortoiseshell 2

25 Mar In Woodbury Field, Bricket Wood, I noticed a Small Tortoiseshell on the grass with a Peacock almost on top of it. Disturbed by me they flew off, the tortoiseshell followed very closely by the Peacock, and again the Peacock settled on the tortoiseshell. I followed, and took off my camera bag hoping to get a photo, but they flew again, with the Peacock once more keeping within a foot of the tortoiseshell, and I lost sight of them.
Is this misguided mating behaviour (I don't know how Peacocks go about mating) or fighting?
Six years ago I photographed a Small Tortoiseshell paying close attention to the rear end of a perched Peacock, by the River Colne near Wall hall Pumping Station

25 Mar I've finally joined the Brimstone club with 2 sightings on my local north of Ware exercise walk. They were some distance apart (no pun intended) but knowing how far they travel could have been the same individual. Also 5 Peacock (2 not far from my house) and in the garden 1 of each Peacock & Small Tortoiseshell. Found some new elm which will be worth watching if still doing my daily walk in June! Liz Goodyear

23 Mar Hounslow. No walk today so I was especially pleased to see a butterfly in my garden. Holly Blue is no surprise here but this is the earliest I've seen one anywhere since I started reporting butterflies to the website 7 years ago. Today's was a male and I was able to enjoy watching it at my leisure, aided by a Christmas gift of new close focus binoculars. It moved in all the familiar ways amongst the Ivy, ignored the Holly which is about flower, visited a Celandine flower once briefly but spent a good bit of time, wings closed in the sun on a damp patch of bare soil in a trough at ground level, largely stationary but walking round a little too. Repeated sightings during the day but nothing to suggest there could be more than one Peter Gore

16 Mar Hounslow. The first identified butterflies of the year for me, 2 Peacocks on the Pevensey loop followed by 3 more on the heath. I was informed by others luckier or more attentive than I that Brimstone and Comma were also flying in this area. An unidentified butterfly on the heath on the 13th was probably a Peacock too, whilst the only other unidentified one seen this year was more likely a Small Tortoiseshell in my garden way back on 8th January Peter Gore
16 Mar My first butterflies of the year - 2 Peacock clashing at Park Farm, Enfield (TQ 2998) at 13:48 hrs, 1 Comma in Rough Lot, Trent Park at 14:26 hrs, 1 Peacock at 15:11 hrs and 1 Small Tortoiseshell at 15:15 hrs at 'Old Golf Course' Trent Park Robert Callf
16 Mar Took a walk around the footpaths of north Ware this morning, but the increasing sunshine couldn't persuade any butterflies to make an appearance. Soon after getting home however, there was a Small Tortoiseshell in my front garden! Although there is a lot of elm in the landscape, the tracks have had all the hedges cut back until I reach a children's play area near to where I live and the elm is in reach (although now a lot is diseased). It didn't take more than a minute to find a hatched White-letter Hairstreak egg - in the past it has taken much longer so a satisfactory result! Liz Goodyear
16 Mar My first butterflies of the year - at Fairlands Valley Park with 4 Brimstone and 6 Comma seen in the early afternoon sunshine Peter Clarke
16 Mar First Brimstone of the year (a male) in our Harpenden garden Alan Jackson
13 Mar At Stanwell Moor, no Brimstones, but instead I saw three Commas at widely spaced intervals

13 Mar St Albans - I've heard of a couple of sightings of Small Tortoiseshells in flight in St Albans area this week. Checking my shed, the number of hibernators is now down to 25 - three less than last week. So altogether five have flown so far this year - that's one sixth of the total which overwintered successfully. No further departures of Peacocks this week - just one of the 13 individuals has flown so far Malcolm Hull
12 Mar At Rye Meads NR - 1 Small Tortoiseshell (my first for the year) Rob Harris
11 Mar On the warm sunny morning, I strolled round my (still very soggy!) local patch at Stanwell Moor, and managed to see no fewer than seven Brimstones, plus a single Peacock and a single Small Tortoiseshell

6 Mar St Albans Shed - Nice sunny morning here, so I decided to check if any hibernating butterflies had yet flown from my shed.
Three butterflies had left - 2 Small Tortoiseshells and 1 Peacock, all from positions on the ceiling where they get most daylight.
28 Small Tortoiseshells and 12 Peacocks remain. One of the Small Tortoiseshells was slowly opening and closing its wings, looking exactly like it was just waking from a deep sleep

3 Mar Five Brown Hairstreak eggs were found on what is probably our last day of searching. Starting at Cranford Park we followed the River Crane south to the edges of Heathrow Airport and back, first mostly of the west bank and returning on via the east bank. One egg was found at Avenue Park, Hounslow and four eggs were found in the vicinity of the flight path of the north runway - one egg was immediately under the flight path! The River Crane was a new catchment area for the butterfly so an excellent final result (Photo: Andrew Middleton)

25 Feb St Albans bedroom wall - first Clothes Moth of the year! Malcolm Hull
20 Feb St Albans Shed: Small Tortoiseshell - 30 hibernating and 1 dead. Evidence of cobwebs around a couple of others shows spider attacks have occurred. The number of hibernating Small Tortoiseshells has reduced by 5 since the peak in late September, though there is evidence of only one corpse. Interestingly there has been no change in numbers during the last three months, perhaps indicating that losses take place relatively early in the hibernation period. Maybe some individuals are more vulnerable, possibly due to the positions they choose in the shed. Peacock numbers are unchanged - still 13, same since the start of September. This is great news as I've found in previous years that Peacocks are more susceptible to predation Malcolm Hull
17 Feb Had a male Brimstone flitting round my Harpenden garden in the afternoon sunshine Robin Pearson
12 Feb Four Brown Hairstreak eggs at Ickenham on blackthorn that missed being flailed close to the Austin's Lane entrance. Later at a site in Hillingdon close to the A40 / River Pinn and railway line 6 eggs were found in what we believe to be a new 2km square (Photos: Andrew Middleton)

8 Jan I never thought my first 2020 butterfly would be a male Holly Blue, but I spotted it beneath a big ivy hedge in Bengeo, it flew several times for short distances. There is a short video on the branch Facebook page

4 Jan My earliest ever sighting and it so lifts the heart. A Peacock fluttering past my window in Northchurch before landing on a house over the Road, I can be sure of the ID as I took a close look. It is likely it was disturbed by a neighbour taking stuff to the dump, but still, a free flying butterfly in the sunshine, lovely Sue Taylor
3 Jan I saw a Peacock at Long Deans NR, resting on a log in the sun. My first butterfly of the year! Jenny Sherwen
