@johnwalterswildife.bsky.socialReposted by @martinswarren.bsky.socialI expect they are heading to France I saw some leave low over the sea at Branscombe, Devon last Sunday whilst Clouded Yellows and a Long-tailed Blue flew to the shore then headed south along the beach presumeably down to Berry Head or Start Point before heading south?
@martinswarren.bsky.socialClearly something to work on, but the community of moth enthusiasts is growing quickly in Europe and a wonderful group in Portugal are leading the way www.reborboletasn.org/the-project. The EU has now adopted moths as one of the compulsory pollinator groups to monitor which will give it a boost.
@pilning.bsky.socialReposted by @martinswarren.bsky.socialI remember seeing dozens flying south across Chew Valley Lake one autumn day. Again the expanse of open water (in this case) allowed the scale of it to be seen.
@johnwalterswildife.bsky.socialReposted by @martinswarren.bsky.socialI often see large numbers of Red Admirals heading south when out on Dartmoor in October - it is easier to see the migration happening on the open moor
@philipamies.eurosky.socialReposted by @martinswarren.bsky.socialSeen the same from Brean Down across the sea.
@martinswarren.bsky.socialCrucial new information on the state of European larger moths. Still lots to lean but these two reports really advance our knowledge. Huge thanks to all involved
@europebutterfly.bsky.socialReposted by @martinswarren.bsky.socialThe new (slightly revised) Red List of European Moths has been published by the EU. A summary and links to downloads can be found on our website. Moths play a vital role in ecosystems and there is also an important new document on how to plan for their conservation

@martinswarren.bsky.socialSurprised to see a couple of Red Admirals heading out to sea this am at Swanage, heading east towards the Isle of Wight (just visible in the mist). Cloudy but 19C.
Are they heading east for the shorter crossing across the channel? Or just a holiday on a distant isle? @dorsetbutterflies.bsky.social

@greenwingstours.bsky.socialReposted by @martinswarren.bsky.socialThe False Apollo (Archon apollinus). One of Europe’s rarest & most beautiful butterflies.
Photos show eggs (laid on Aristolochia), the striking caterpillar, and both sexes of the adult (female top, male bottom).

🦋 There's a reason why our tours fill fast, months or years in advance: we're dedicated and reliable at finding our guests the Western Palearctic's rarest and most beautiful butterflies. Two places secured today for Marvellous Morocco 2028:
@dorsetbutterflies.bsky.socialReposted by @martinswarren.bsky.socialLong-tailed Blue alert. Another Dorset sighting, this time on Brownsea Island. Keep an eye out for these rare migrants. www.dorsetbutterflies.com/2026/10/long...

@grahancock.bsky.socialReposted by @martinswarren.bsky.socialWoohoo, it's now live! We show, using four lines of evidence, that butterfly wings can create illusory motion effects!

@jamescbr.bsky.socialReposted by @martinswarren.bsky.socialSimilar story here in Suffolk, UK. The warmer summers means we can sometimes have two hutchinsonii broods but, without rain for the foodplants, the last brood is much smaller. At least it is expanding in the north.
@martinswarren.bsky.socialJust like old times for me in Harlow Carr gardens near Harrogate, Yorkshire. several Small Tortoiseshells mingling with Red Admirals, Commas and a few Peacock and Painted Lady. More STs (3) than I have seen all year down south! @bcyorkshire.bsky.social @savebutterflies.bsky.social
