Amazing scenes from The River Frome in Dorchester Dorset. London road had just closed when I got there at 1220 (despite being a causeway). Videos and Photos #stormchandra 1/7
27.01.2026 13:43 — 👍 31 🔁 7 💬 2 📌 1Thymelicus hamza with closed wings. I found it typical that the sandy ground color of the underside hindwing is completely surrounded with an orange border. I didn't see the local subspecies of Thymelicus acteon so I don't know how good this is for an ID feature on pictures of individuals with closed wings. In my European pictures of T. acteon I haven't seen an individual however with such a continuous orange border.
Thymelicus hamza, male with open wings. The pale spots in frontwing tip are lacking or very vague. The darker brownish color is more confined to the area below the androconial stripe, unlike in T. acteon (although they probably look darker when abraded).
While preparing for Morocco last year I only found few Thymelicus hamza pics online, a NW African endemic skipper, so I was afraid it'd be scarce. I found it to be widespread however, I guess the lack of pics is mainly due to people thinking skippers are boring & hard to ID? #dailylepi #vlindermaand

Caloptilia honoratella
Yponomeuta irrorella
At least 621 species were recorded at St Mellion in 2025, 105 of which were new for the garden. Highlights included
Yponomeuta irrorella (Scarce Spindle Ermine): 2nd for Cornwall, Caloptilia honoratella (Pale Maple Stilt): New to Cornwall & Glaucous Shears: 1st Cornish record since 1982 #teammoth
I found the first Clouded Yellow caterpillars of 2026 today on the transect.
Only 2 seen, but clear evidence that they continue to overwinter at Southbourne despite what the British winter weather is throwing at them.
Southbourne

Another amazing aspect of nature, this time electrostatic pollination!

Our featured tour this week is Spring Butterflies of the French Pyrenees. A tour that explores a richly butterfly-laden area of France in late May, and guarantees a donation to support @europebutterfly.bsky.social. (1/2)

Last summer was nearly 2C warmer than the 1961-90 average, especially in spring. No wonder butterflies bounced back. But just think how bad populations would be if we did not have global warming.

Before: a heathland-covered slope encroached with Gorse, Sallow and Cotoneaster.
After: Gorse, Sallow and Cotoneaster have been removed from the slope, exposing the heathland and patches of bare ground.
An intrepid band of volunteers braved the rain today for Cornwall Butterfly Conservation's work party at Wheal Maid. We were removing encroaching Gorse, Sallow and Cotoneaster from a south-facing slope to restore the heathland for Grayling and Silver-studded Blues.

All of our butterfly and orchid holidays generate a donation to support the invaluable conservation work of our friends at @europebutterfly.bsky.social and @bsbibotany.bsky.social respectively. That support is important to us, and we know it's important to our guests too.
24.01.2026 10:45 — 👍 17 🔁 4 💬 0 📌 1Yet more worrying data on the decline of European butterflies, this time from Finland. We must find a way of combining agriculture and biodiversity, it can be done and many NGOs are showing the way www.rspb.org.uk/helping-natu...
23.01.2026 22:24 — 👍 12 🔁 8 💬 0 📌 0Save the date! Join us on Sat 28th March 2026 for the UK Butterfly Recorders meeting.
This free event is open to anyone intersted in butterfly monitoring. We'll present the 2025 UKBMS results, update on other monitoring schemes and talks about butterfly ecology.
A new study shows that butterflies, unlike birds, are declining in Finnish agricultural landscapes:

Great new research shows that light pollution prevents activity in the critical twilight period (just after sunset) in a moth and spider species. 🕷️🦋💡- this calls for mitigations targeting this critical time period. Read more in our dispatch:

The Great Plains are known for waves of grass—and herds of cattle grazing “out on the range”. But the native wildflowers dotted throughout are critical for the many pollinators that call these places home. And those same plants are actually a nutritious meal for livestock!

Excellent to see this work going on with our Branch volunteers and Hilfield Friary folk. Well done everyone
