The new European Butterfly Red List is published today, with worrying findings. Over 1/4 (28%) of Europe’s 442 species are threatened with extinction or are close to being so. The situation is far worse for our 148 endemic species, 40% are now threatened or nearly so www.bc-europe.eu/webpage.php?...

"Only a fool will go chasing a male Orange-tip in the heat of the day!" (Paul Atkin) ... we're having a debate at UK Butterflies that will allow us to create a 'Guide to Responsible Butterfly Photography' so do join the conversation at www.ukbutterflies.co.uk/phpBB/viewto.... 📷 Neil Freeman

Hi Richard - the key diagnostic is found on the upperside hindwing although, based on your photo, I'd suggest that this is L. maera which has a paler underside (and is larger) than L. petropolitana.

Another way of thinking about it is, in the absence of Cotesia glomerata, the numbers of Large White would get out of control and you wouldn't have any cabbage with your Sunday roast 😀 These types of relationships are so important to maintaining a delicate balance! Great photos of the parasitoid!

I believe that the two subspecies can be separated based on appearance - at least, britannicus can be separated from whatever subspecies is found near us in mainland Europe (there's some dispute about this!)
ukbutterflies.bsky.social
Might be worth rearing it through for more certainty regarding subspecies

I can't find any mention of Fennel being used in the wild by ssp. britannicus, although it will take it in captivity. The location would suggest britannicus and this should be documented (e.g. in Ent. Rec.)

Nice find! This looks like an intermediate form between helice and the normal form. All abs are listed at www.ukbutterflies.co.uk/aberrations...., but there's no obvious match.

Hi William - and congrats! We're keen to ensure that this sighting is recorded in an appropriate entomological journal (such as the Entomologist's Record) so that it can be formally added to the Checklist of the Lepidoptera of the British Isles. Do contact me for more info ([email protected]).

Congratulations to William Brame @landguardbirder.bsky.social for realising this was a different white butterfly. Now confirmed by @chrisvanswaay.bsky.social as a Southern Small White - the first seen in England. As it is a female let's hope it has been laying eggs. @matthewberry.bsky.social

Nearest "known" colonies :)

Given the weather today, we focused on the ecological aspects of our butterfly fauna; geology (chalk, clay, sand/gravel), habitats (grassland, woodland, heathland), flora and fauna. Here are some of the butterfly eggs we examined - White Admiral, Small Blue and Small Copper (library pics).

Thanks for coming along, Nicola, and I look forward to our next meet!

Enjoyed a fantastic walk guided by the hugely knowledgeable Peter Eeles, over a neighbouring estate doing extraordinarily good & innovative things for wildlife. Truly exciting. Learning to spot caterpillar webs in the fields, & tiny white admiral larvae in the woods! @ukbutterflies.bsky.social

That's certainly one of its larval foodplants 😜

When I started UK Butterflies in 2002, I had no idea that it would attract such interest! This is a 'shout out' to Vince Massimo, who has spent over 2 decades curating our image library from over 450 contributors. This recent image from Neil Freeman did make me laugh - name that species!

Yes - female Silver-washed Fritillary
