Saving butterflies, moths and our environment
Brown Hairstreak egg finds at Warren Farm LNR. I decided I wanted to visit Warren Farm LNR in Hanwell, following the exciting news that they had been successful in their fight to gain LNR status! Information was that there was a lot of blackthorn but this wasn't the case but I found 2 Brown Hairstreak eggs amongst some sucker growth. I then visited Trumper's Meadow which is between the Grand Union Canal and Warren Farm and found 3 more eggs (only 2 were viable). (for info I planned this trip before seeing on iRecord a late entry of an adult sighting from August 2023 close to the Meadow!) [Posted by Liz Goodyear]

IMPORTANT. Please read about the revamped version of our branch website. Welcome to the revamped version of our branch website. Our branch website is modelled on the Hants/IOW branch website. As well as the visual attractiveness of this website it incorporates many important features including increased security and improved performance. One significant feature is the use of News items including sightings submitted by observers. Rather than sending emails for submission it is better to have this done automatically and then verified by an administrator. Another factor is online editing. Some users can be granted access to edit certain web pages themselves instead of them being done manually by an administrator. Other notable features are included as shown on the horizontal menu. In the past, we have allowed observers to send emails for submission of records to appear on the sightings page and to be recorded on a 'sightings' database hence the requirement for a specific location like grid reference. Now, however, it is common practice to submit records formally through national databases like iRecord. Any sightings reported via the 'Submit News' function will NOT be recorded on any database so it is not necessary to be specific about location. To submit a news item (sighting, online talk, field trip or any significant event) click on the 'Submit News' button under the 'News' button on the horizontal menu as shown in Photo 1 (click to expand) below. You should be presented with a 'News Form' as shown in Photo 2. Fill in the details as required. Up to 3 photos can be uploaded. It is recommended that each photo is less than 2Mb in size otherwise you may be asked to resize or crop the image. After completing the form, click the 'Preview' button to inspect the resultant action. If satisfied, click the 'Submit' button. The item will have to be verified by an administrator before it appears on the news item list as represented on the 'News' screen (see Photo 3) and its title on the right hand side on the Home page. Finally, I must thank Pete Eeles for his invaluable support. [Posted by Peter Clarke]

Brown Hairstreak eggs at Whitings Hill/Open Space, Barnet. I had had on my radar Whitings Hill/Open Space in Barnet, a short distance from the previous Dollis Brook sightings even to point of knowing where to park but hadn't got around to visiting. However last week Rohan tried to survey the site but was defeated by torrential rain and mud but reported it had a lot of blackthorn. This was far too tempting so I visited today. The mud is horrendous but there is so much blackthorn, in fact too much and much of it is well budded and almost in flower! Over a period of 3½ hours I found 4 Brown Hairstreak eggs well distributed across the site so I suspect there were many more! Thanks to Rohan for reminding me of this site and for his and everyone else's tremendous finds this winter! This was definitely my last survey as the budding is really making it too difficult now to find eggs! Hopefully these sites will dry out a bit by the summer! [Posted by Liz Goodyear]
White-letter Hairstreak egg at Garston Park. I returned to Garston Park in Watford today to make sure I hadn't missed any blackthorn on my previous visit! Next to a nice stand of blackthorn I realised there was some nice flowering elm low down and after some searching I finally found a hatched White-letter Hairstreak egg – I had forgotten how small they look when hatched!

Female Brimstone Nomansland Common. Working with conservation volunteers on Nomansland Common clearing Gorse, although the air temperature was low, if felt warm in the sun in front of the trees, and a female Brimstone flew past and settled on the Gorse about knee high. It then clouded over, cooled down, and the Brimstone stayed settled. I decided to photograph it when we finished work, but cold rain then started (I understand it fell as hail nearby in St Albans). I assume this was why the Brimstone stayed put despite me accidentally shaking the Gorse a few times when I caught on brambles, and pushing my compact camera to little more than an inch from it for maximum magnification.

Brown Hairstreak eggs near Harrow. Following on from recent Brown Hairstreak egg finds in the Stanmore area I decided to revisit an area of blackthorn off Old Redding near the Harrow View point today first seen in January 2022. It is a public footpath with prunus along the hedge line – in total I found 8 Brown Hairstreak eggs but to my surprise I looked at two probable Cherry Plum bushes that were already flowering and found 2 eggs despite the flowers! Another blackthorn twig had 3 eggs very close to each other [Posted by Liz Goodyear]

Egg finds in Totteridge area. Having visited Totteridge now four times, the last on Tuesday when it rained - I could only find 4 more Brown Hairstreak eggs but all in slightly different areas, I decided to go somewhere new! I started from Quinta Park in Barnet and followed the Dollis Brook Loop walk to Totteridge Fields. Over a 3½ hour period I found 3 Brown Hairstreak eggs which would be a new 2k so although only 3 its 3 more than had been found there!!! I was hopeful that Totteridge Fields LWT Reserve would come up trumps but the blackthorn is not the type of blackthorn I like and a lot had been cut so a wasted walk! However the fields between Totteridge Common and Barnet (Mays Lane) are lined with blackthorn and there must be more eggs to be found? Be warned the mud is dreadful in places!

Brimstone at Hounslow. The butterfly year here began early with a male Brimstone on the heath near the railway. It was shortly followed, albeit in the next tetrad along, by what was probably a Comma and then much later a likely Peacock was seen to fly on the far side of Pevensey Road meadows. This could well have emerged from someone's garden shed in the back gardens and it certainly showed more interest in matters the other side of the fences there than in the wide open spaces of the meadows, thus making it impossible for me to confirm that guess either. Nothing else seen so just one definite so far but clearly likely that the hibernating species are around in small numbers for now. Still working on doing things differently. This was the normal walk of just over 12 miles modified to include extra time on the Marshalling Yard (which is now officially labelled as such and as a nature reserve - good news for sure even if I wasn't rewarded by the butterflies.
