Did you know the mostly likely Yorkshire species you will see first, each year, is a Brimstone. They are rarely the earliest but awoke in force in the warm sun of 25th Feb. More than 5 times as many were seen than any other species, 2nd was Peacock, 3rd Comma and Red Admiral so far is zero!

Its been a better year for the Clouded Yellow and they are now making their way south for the treacherous trip home. This individual was captured by Chris Cox at Spurn yesterday where there have been regular sightings recently. Also flying currently are Red Admiral, Small Copper and Holly Blue.

There is no reason why this species is not spreading through Yorkshire in our warming world and is already present at Pleasley Park just over the border in Derbyshire

A fascinating study at Leeds University reveals for the first time how its possible to use weather radar data to estimate total numbers of flying insects. They found 11 trillion insects daytime increasing with climate warming while at night strong decline after LED's in urban heat and light islands

With a massive third generation will Small Copper be Yorkshire's Butterfly of the year? Please submit your butterfly records by 16th November 2025 for them to be included in the Annual Report. Please submit on iRecordbutterflies, the Sightings site on the branch website or UKBMS for transects

Front cover of the European Butterfly Red List, showing Polyommatus humedasae. The report can be downloaded at https://www.bc-europe.eu/webpage.php?name=red-list-butterflies-2025

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?...

This graph from @metoffice.gov.uk says it all about this summer's weather. Every month was at least a degree warmer than the average 20 years ago. Butterflies mostly did well but how will the drought have affected them? @savebutterflies.bsky.social

UKBMS data is crucial for research. A new paper uses 45 yrs of UKBMS data to examine how extreme climate events affect butterfly populations in England. Heatwaves during hibernation or early life stages and heavy rain during later stages have -ve effects.

An influx of Clouded Yellow since 4/8. They can be seen in many flowery places and clover fields. Popular spots include Ledston Luck, North Cave wetlands, Ripon wetlands. Look for a medium sized dusky orange butterfly in flight. You rarely get to see the upperside so thanks go to Tony Wilson.

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
