Its week 23 of the UK Butterfly Monitoring Scheme! September is here and we're into the last month of the survey. Some summer species may no longer be on the wing, but as we're having a bumper year, keep an eye out for second (or even third) broods of some species.

We would like to say a big THANK YOU to all the volunteers who contributed to the Wider Countryside Butterfly Survey this year!!! 🎉 👏 🦋 The survey window closed today, so be sure to enter all of your data to the UKBMS website by the end of October. @bbs-birds.bsky.social

If you're participating in this years Wider Countryside Butterfly Survey, you have THREE DAYS to complete your final survey if you've not already done it. The window for this survey closes at the end of August. Thanks all! Full details here: ukbms.org/sites/defaul... @bbs-birds.bsky.social

Wider Countryside Butterfly Survey participants – there are just 5 days remaining before the survey period ends. The WCBS wraps up at the end of August, be sure to complete your final survey if you haven't done so already. Full survey details here: ukbms.org/sites/defaul... @bbs-birds.bsky.social

Not that long ago in August Buddleia's could be covered with Small Tortoiseshells (A urticae, kleine vos). On eBMS transects and 15min counts (www.butterfly-monitoring.net) this butterfly is now restricted to higher elevations or latitudes. Open squares=counted in that period.

Its week 22! Did you know that the sightings you enter via UKBMS also connect to iRecord? This allows county recorders, species experts, and researchers to access them. If you have an iRecord account, you can view all your UKBMS records alongside your other records. irecord.org.uk?check_logged...

A new study from @ukceh.bsky.social using UKBMS data explores the impact of Agri-Environmental Schemes on butterfly abundance, species richness and diversity in England. Some positive relationships uncovered 👍 Learn more here - buff.ly/a0AKpBf buff.ly/yjNJdeE

Join us at the UKBMS 50th Anniversary Conference! We can't wait to celebrate this milestone yr 🎂 Join us for a day of butterfly science, celebrations and chatting with other butterfly enthusiasts. Book your free place - www.eventbrite.co.uk/e/uk-butterf... Places are limited, book soon! #UKBMS50

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. Its worth a read - buff.ly/nOU2Zod

UK Butterfly abundance Indicators for 1976-2024 have been released, showing an 18% decline in overall butterfly abundance for the UK. Habitat specialists have fared worse, declining by over a third. Check out the full statistics here ⬇️ buff.ly/1AIDB3J

Today is the start of week 21. The deadline for submitting all your data for the UKBMS is the end of October - so get ahead and enter all your data to date. This gives our Coordinators and species experts time to check, validate and verify your records.

Brown Hairstreak at Malling Down @sussexwildlife.bsky.social reserve, first time they have been recorded on the @ukbms.bsky.social transect Silver-spotted Skipper are making a recovery following several poor years at the site. Chalkhill and Adonis blue out. Loads of Wall Brown.

Its week 20. Thinking of setting up a new transect for next year..? Now is a good time to trial it and make any tweaks it so it's ready for the next season. Once finalised, the route can't be changed, so testing it first is crucial. More info here: buff.ly/zQyStix

(1/) The last butterfly species that we focus on as part of this series is Gatekeeper. This species is also known as the Hedge Brown. It is mostly found in the southern half of the UK. Species information: butterfly-conservati... @savebutterflies.bsky.social @ukbms.bsky.social

Its week 19! And we're into August! If you're off on your hols and have someone covering your transect for you, make sure they are linked to it on the UKBMS website so they can enter data and signed up to Assemble. UKBMS website: ukbms.org/MyData Assemble: ukbms.org/health-safety

(1/) Today, we focus on Ringlet Butterfly. This darkly coloured species with distinctive rings on its wing is often seen feeding on Brambles. You can find out more about it here: butterfly-conservati... @savebutterflies.bsky.social @ukbms.bsky.social #CitizenScience

Our last butterfly to emerge is now out at Fontmell Down with a few Silver-spotted Skippers seen on Friday www.dorsetbutterflies.com/2025/07/silv...

A full report of our latest European Grassland Index has just been published. It gives individual species trends as well as the overall decline of 50% since 1991-2023. Another update will be coming soon to include 2024 (which was not a good year for many butterflies) doi.org/10.5281/zeno...

Its week 18! Keeping up to date with entering your data is really important so that we can carry out the analysis swiftly once the season ends. Take some time to check through your data and get it all entered. There's a handy videos showing you how to do this ⬇️ ukbms.org/sites/defaul...

Its week 17. Keep at it! The more weeks that you can consistently record, the more valuable the data. If there are too many gaps when the transect isn't walked, we cannot use the data to produce butterfly trends. #UKBMS50

Week 16 starts today! What has been your favorite sighting on your transect walk so far this year..? #UKBMS50

Its week 15! As we head towards the summer holiday period, you may want to get someone to walk your transect if you're away. If you do, they must be registered on Butterfly Conservations volunteer portal - Assemble. Register here - ukbms.org/sites/defaul... #UKBMS50

To mark the start of the WCBS survey season, we've just published the findings from the 2024 surveys. Grab a cuppa (or a chilled drink!) and take a read here ⬇️ ukbms.org/sites/defaul... There's some great articles on how to identify day-flying moths and the importance of farmland habitats too.
