Please email Peter Clarke (peter.clarke4@ntlworld.com) to send in your news.

Please include grid reference (6 digits preferred but 4 digits will do) or post code for your sightings. Grid reference can be obtained here. Most, if not all, sightings listed here with sufficient detail given, will be added to the branch database but see note below.

You can use the iRecord app to submit your records. Alternatively, you can enter your records using a spreadsheet which can be downloaded here for butterflies or moths. More details can be found on the General Recording page for butterflies and Moth pages for moths.

NOTE: To avoid any duplication, if you are submitting records to the Branch Recorder (Andrew Wood) and also have any of them listed on the sightings page please let Andrew know.

Photos are welcome and a selection will be posted on this webpage but please keep these to a reasonably small size. Provide a link if your photo is on an external application like Flickr. Alternatively post your photo on Facebook.

February

Date Description Recorder
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)

26 Jan Male Spring Usher of 'melanic variety' at ASDA Southgate (Identified mostly on size and shape, also seen at this site before but not this variety. Confident that it was not a Dotted Border - which seems to be the only confusion species) Robert Callf
21 Jan Red Admiral enjoying the sunshine at the Warren, Bengeo, this afternoon Chris Benton
18 Jan Red Admiral in Bushey front garden this morning David Gower
17 Jan Amazed to see a Red Admiral flying around in Gordon Road on my walk to Bounds Green tube at 11.30 this morning, it felt far too cold to be seeing this Miles Attenborough

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

7 Jan Comma from my Stevenage moth trap Ben Sale
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
