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.

Brown Hairstreak eggs at Totteridge. I returned to Totteridge today - it was far too sunny to see eggs properly and terribly muddy! I ended up with a total of 10 Brown Hairstreak eggs, 6 in the same area as Wednesday's eggs finds near Folly Brook but also 3 in different areas of the scrub and a 4th close to where the very first egg in 2020 was found in the main area.

Brown Hairstreak eggs at Totteridge. I have spent the last two days searching the main fields at Totteridge and found 20 Brown Hairstreak eggs in total. Yesterday it was a matter of finding 4 quite quickly and then waiting for at least another 1½ hours before the next eggs were found, today it was a bit easier. However, the more interesting was that today I finished by crossing the Folly Brook where in previous years much searching for eggs has been conducted with no success and 3 Brown Hairstreak eggs were found quite quickly - I will need to return as there is still a lot of blackthorn to check here!

Brown Hairstreak eggs in Hertfordshire, at Merry Hill, Bushey. Ian Watts and myself decided to look at Merry Hill in Bushey following on from our close but not close enough Brown Hairstreak egg find last week. There is a lot of blackthorn although some looked unsuitable - some areas ticked all the right boxes, oak, ash, bramble and nectar! In the end we found 14 Brown Hairstreak eggs although nothing for the last hour!!! We think the site, or at least where the eggs were found is about 1.5km inside the Hertfordshire border so we now wonder where else they can be found! [Posted by Liz Goodyear & Ian Watts]

Brown Hairstreak eggs in London Loop between Aldenham Country Park and Stanmore Common. So close but so far!! Following on from Rohan Harris' recent very successful Brown Hairstreak egg finds at Stanmore Country Park, Ian Watts and myself decided to try and find an egg in Hertfordshire today so we followed the London Loop from Aldenham Country Park towards Stanmore Common. Needless to say the first decent blackthorn we found was where a ditch forms the boundary between Greater London and Hertfordshire. We found two Brown Hairstreak eggs one was 25 yards from the county border and the second was even closer at 10 yards! After that on our very muddy route back via Elstree, there was more blackthorn along the London Loop (which we didn't search) but after we turned off back towards Elstree we found very little!
