Saving butterflies, moths and our environment
Sightings from Stanwell Moor. Another very warm day for November, and some sunshine too after lunch. After finding a couple of Red Admirals (I don't think either were any I've seen in recent days), I then disturbed a fresh male Common Blue from the grass. However, it sailed off directly into the low sun and I lost track of it. No Small Coppers appeared today, but in the same general area where they've been flying I found two Small Heaths, one of which was the one I saw here on 28th October. I've never seen the species anywhere in November before. [Posted by Dave Miller]
Clay Hill area of Enfield. In light of a report on social media of 4 Brown Hairstreak eggs being found in the Picketts Lock area of Enfield, I revisited the Clay Hill area again, hoping that I might find some Brown Hairstreak eggs on the extensive blackthorn - unfortunately I failed but I did find a White-letter Hairstreak egg on an elm that I have looked at on several occasions over the years with the last success in 2021! This was at least some form of compensation! [Posted by Liz Goodyear]
Merry Hill (Woodland Trust) Brown Hairstreak egg rescue. We were asked by the Woodland Trust to search for Brown Hairstreak eggs that were vulnerable to a programme of imminent hedge and tree work around the site. These eggs were subsequently rescued and put into safe storage for return to the site when the work has been done. The areas that needed to be checked were scattered across the site and varied in quality. In total a minimum of 55 eggs were rescued and casual sampling of blackthorn that was not at risk yealded 42 eggs (32 yesterday on one hedgeline alone!) - completed over 3 days by myself, Pete Fewell and Rick Vickers [Posted by Liz Goodyear]
Sightings from Stanwell Moor. Just two Red Admirals today, sitting not far apart in the brief spell of sunshine here around 1030 this morning. The feeble November sun couldn't provide enough energy to get through the cloud and wake anything else into action for the rest of the day despite the air being warm. [Posted by Dave Miller]
Sightings from Stanwell Moor. After the overnight rain there was cool sunshine through the day, but I managed to find a few butterflies on my local patch. The Red Admiral came as no great surprise, but I was pleased to find a Small Copper still flying in the usual spot and also a male Small White. However, the best of the lot was a fresh male Clouded Yellow that I only managed to photograph from a distance before it headed off downwind in the stiff breeze and I lost sight of it among the sea of yellow flowers that persists here at present (mostly bristly oxtongue and some hawkbit).

Delicate at Southgate. 1 Delicate at ASDA Southgate this afternoon & 1 White sp [butterfly] edge of Water Grdn/Trent Park this afternoon - only seen in flight. [Posted by Robert Mark Callf]
Saffron Green area (east of the A1). 2 Brown Hairstreak eggs found 400m north west of Saffron Green Open Space (700 north east of Rohan's find last week). In 2003 the late Nigel Agar, was convinced that this HCC owned blackthorn rich open space could support Brown Hairstreak and as a result the site, has been searched many times since then with no success - even this week! Hopefully we can prove that Nigel was right one day maybe next year? Also found today were 8 Blue-bordered Carpet eggs and 2 Oak Eggar caterpillars! [Posted by Liz Goodyear]
Sightings from Stanwell Moor. Morning sunshine again today near Heathrow after a wet and grey day yesterday. Six butterflies seen: Red Admiral (2), Small Copper (2), Small Heath (1), Small White (1). The last of these was a surprise as I'd not seen one for nearly a week and had thought they were finished for the year. [Posted by Dave Miller]

Sightings from Stanwell Moor. Once again the day started with sunshine, and it was a little warmer again. I found 15 butterflies in all on my usual local walk, including the same three Small Coppers and eight Red Admirals in all. I disturbed a Peacock from the ground at one point, and near the Coppers I found the same Small Heath I'd seen on 25th - it must be a hardy soul! Nearer home, I came across a Comma that I think had found a sap run judging by the cluster of grey bugs on the same bit of tree. Finally, nearby there was another Small Copper, a fresh male.

Sightings from Stanwell Moor. Warmer today, but breezy and the morning sun gave way to cloud cover by midday once again. The trio of Small Coppers seen yesterday were all still around, but had been joined in their relatively sheltered spot by a fresh male Common Blue. The only other butterflies seen today were a pair of Red Admirals basking quite close together on the brambles. [Posted by Dave Miller]
Sightings at Trent Park. 1 Red Admiral & 1 Silver Y along Leeging Beech Gutter near 'Three Bridges' Trent Park this afternoon between 1316 & 1318 GMT. [Posted by Robert Mark Callf]
A few more Brown Hairstreak eggs at South Oxhey Playing Fields.. After yesterdays eggs found at South Oxhey Playing Fields we covered a bit more area than yesterday. We found a further 10 eggs with 2 near where the only one found last year was recorded and the rest a found nearby with the furthest by Hampermill Wood. 2 eggs found on older growth with Lichen on. We have marked up again with the red wool I had left over from last year at Prestwick Road Meadows. There are still bits that haven't been searched for eggs yet but 57 over the weekend is far greater than we imagined! With Rohan's count of eggs found at Croxley Moor it does seem that a Brown Hairstreak revival is going on in this corner of Hertfordshire!! [Posted by Peter Fewell]
Sightings from Stanwell Moor. An even chillier start to the day for me today, but once again there was some early sunshine - enough to bring a few butterflies out. Two Red Admirals and a Comma were probably individuals I'd seen in recent days, but the Small Coppers were more interesting. I found three in one spot - I think I may have seen them all before, but never more than two at once. However, close scrutiny of the photos revealed three different individuals. I also found another one in a completely different spot, but didn't get a photo unfortunately. The weather is now set to become warmer again, with at least a bit of sunshine, so hopefully the season will continue for a few days longer. [Posted by Dave Miller]
South Oxhey Playing Fields egg search. After the Brown Hairstreak egg rescue last week at Prestwick Road Meadows we were keen to look for eggs at South Oxhey Playing Fields after seeing an adult late August. I'm glad we did as only one egg was found last year but Saturdays find was far better than expected. A total of 47 Brown Hairstreak eggs were recorded 34 mostly at the end of the rainbow starting at the corner of the hedge-line. The rest not far behind where the photo was taken. Rick got off to a flying start finding the first 4 eggs then I caught up by finding 4 eggs on one stem and it went from there. The eggs were marked up as we don't know of any potential management plans for this site so far. Hopefully these bits will be left over winter. Rick tagged the grid codes so he will be sending that data to Liz. We didn't get time to search the area last years egg was found yet, so more searching needed at this site. [Posted by Peter Fewell]
