An awesome video from Michael Williams taken a few days ago in South Derbyshire of Purple Emperors exerting their power over Comma's and Red Admiral's. Yorkshire has also 'fallen' purple with three sightings of 'HIM' this year from Sprotbrough, Guisbrough and York confirmed. youtu.be/ZSKUQgC1tHM

It's the Big Butterfly Count and we are at Tropical World Leeds. The Privet Hawk is proving a real crowd pleaser along with a very full moth trap. Lots of interest from visitors.

Thanks Matt

White-letter Hairstreak

Purple Hairstreak

My first visit to the Floodplain Meadow in Great Ayton, North Yorkshire. Butterflies were numerous and I managed to record two new species for the area, the Brown Argus and the White-letter Hairstreak, classified as Vulnerable in the UK. @bcyorkshire.bsky.social @nymnptrust.bsky.social

🌿🐛🦋📢 Two exciting new Peatland Project Officer jobs with @savebutterflies.bsky.social in northern England! Adventurous ecologists wanted to investigate how Large Heath and other butterflies & moths can benefit from extensive peatland restoration. butterfly-conservation.org/jobs

A bit surprised to find a Roesel’s Bush-cricket in our garden in North Yorkshire. They are certainly moving north at a pace. @northyorkmoors.org.uk According to www.inaturalist.org/observations... one of the furthest north ever recorded in UK.

Our work is not done / never done! With around 300 species assessments still to publish on the IUCN Red List, there is still a lot to learn about the conservation status of these amazing species!

Another incredible day on the @greenwingstours.bsky.social tour in the Italian Alps. Among the 57 species found today, it was the Apollos that really provided the 'wow' factor - a nice male showing all of its red spots & a mated female with a 'sphragis' on her abdomen that prevents further pairings.

Large Heath after a couple of years absence on Fen Bog has returned with 4 seen on the transect yesterday which is very good news. Butterfly conservation are involved with a large new habitat restoration project nextdoor to expand habitat for this species.

Great to see so many Small Tortoiseshells this year. A good number enjoying our patch of thyme in the garden. @savebutterflies.bsky.social @northyorkmoors.org.uk @bcyorkshire.bsky.social

A short trip to Commondale in the North York Moors to see the Small Pearl-bordered Fritillaries. @northyorkmoors.org.uk @savebutterflies.bsky.social @bcyorkshire.bsky.social

Visited Norfolk over the weekend for #WorldSwallowtailDay with my fellow trustees and advisors of @sbbtrust.bsky.social
always feel very fortunate to see the Swallowtail (Papilio machaon britannicus) such an iconic species but under threat from rising sea levels and flooding of its habitat.

Happy #WorldSwallowtailDay The SBBT team have been out searching for the British Swallowtail in the Norfolk Broads in the UK.

A good number of Small Blues were seen in Teesside, close to their original release site. There was however no Kidney Vetch in sight when there is normally vast swathes of it. This is concerning for future generations. It's supposed to be a drought tolerant plant. @savebutterflies.bsky.social

A small number of Duke of Burgundy were found sunning themselves at the Hawnby Hill site in North Yorkshire. The few visible primroses were beginning to look a bit dry. @bcyorkshire.bsky.social

Green Hairstreaks still around at the Hawnby Hill site in North Yorkshire today. @bcyorkshire.bsky.social

My 1st Swallowtail of the year at Strumpshaw yesterday @norfolkbutterflies.bsky.social
