And finally the super bright Scarce Copper.

Ed Horncastle @edhorncastle.bsky.social · 11/08/2026
More on the copper theme of the Spanish pyrenees. I believe these are purple shot coppers. Male and female.

A great two weeks in the Spanish pyrenees. The butterfly highlights were the coppers. I believe these are all Sooty Coopers. Feels a rather drab name for a wonderful beautiful butterfly. Male and female. Am I correct @dunnjons.bsky.social ?

The fields of North East Dartmoor feel pretty Mediterranean at the minute. A couple of Clouded Yellows around today. @bcdevon.bsky.social @savebutterflies.bsky.social

First Clouded yellow on my local summer butterfly patch. So many meadow browns. Good numbers of common blues and gatekeepers and a few marbled whites.

More purple hairstreaks low down and almost on the ground than I ever seen. Perhaps staying out of the heat. Loads of beautiful demoiselles and good numbers of Brimstones around too.

White admiral males have set up territories near shady honeysuckle. Lots of fighting and courting going on in the heat today. At one point there were 5 spinning around each other above my head. Magical day @savebutterflies.bsky.social @bcdevon.bsky.social

Purple hairstreak numbers building. About 30 on my favourite few oaks at 630 this evening. Fighting for the best spots in the sun. @bcdevon.bsky.social @savebutterflies.bsky.social Mainly males but the bottom left picture is a female. A great site to see.

White admirals are my favourite UK butterfly. They live in the woods, are black and white, elusive, beautiful and if you put in the work can be very rewarding. A lot like my favourite bird! 5 seen this afternoon as the sun came out. @bcdevon.bsky.social @savebutterflies.bsky.social

Freshly emerged High Brown fritillaries on Dartmoor. Not many out yet. 2 seen in the sunny spells between the rain this morning. A magnificent butterfly. Let's hope for many more very the next few weeks. @bcdevon.bsky.social @savebutterflies.bsky.social
Concave forewing and indented black spots are a tell that you are looking at the rare high brown fritillary Under wing showing the brown red spots that help distinguish the high brown from the dark green fritillary

4 species of fritillary today but didn't capture the ragged pearl bordered fritillary. 3 in @bcdevon.bsky.social and 1 in @bc-cornwall.bsky.social . Gotta love the fritillaries in the south west. @savebutterflies.bsky.social
Marsh fritillary at my local site on Dartmoor. Small Pearl Bordered fritillary on a heath spotted orchid just down the road. Two heath wishing there was more sun in the Tamar Valley today.Marsh fritillary trying to stay dry in the rain on Dartmoor.

A yearly adventure across the border to @bc-cornwall.bsky.social to look for heath fritillaries. Over 50 seen today even in mixed conditions. They were easier to photograph in between the rain. One of my favourite butterflies and favourite places to see them.

Looking for the exits. The LSW chicks are very restless now - sticking their heads out the hole and yelling at their parents. Fecal sacs are no longer being removed. A chance they could fledge today at ≈22 days old. Both appear to be female #HantsBirds #NewForest @lesserspotnet.bsky.social

There are now two more female Lesser Spotted Woodpeckers out in the world! What a joy it’s been to share this patch of woodland with these incredible birds for the last 11 days. Thanks to @lesserspotnet.bsky.social for the guidance. The clearing feels very quiet now! #HantsBirds #NewForest

Back this morning to see if the nest was empty. Surprised to see the male chick. Watched for an hour. No feeding from adults. One quick visit followed by a close visit and the Male fledged! Female checked the empty nest and then they were off together. Absolute joy. @lesserspotnet.bsky.social #Birds

What a wonderful spring Ive had following these lesser spots from drumming to fledging. Fun video from one of the few visits today. The parents were trying to force them out through hunger. Got a bit competitive in the nest. @lesserspotnet.bsky.social

Ed Horncastle @edhorncastle.bsky.social · 25/05/2026
The lesser spots have finally fledged! Want to see it don't watch this video! Watching through my bins and didn't notice my camera had frozen in the heat. Watch the pre-behaviour and you can hear the bird fly away calling at 31 secs. Then her siblings realise at 37 secs @lesserspotnet.bsky.social

Lesser Spots still not fledged. Typical behaviour this morning. Chicks calling from the hole, Female brings a quick feed then tries to call them out. They didn't want to come out. Has to be tmrw but I've been saying that since Thursday! @lesserspotnet.bsky.social

Some more footage of the lesser spot pair Ive been following since February. Ive loved every minute. Hopefully tmrw I will see the chicks, these two have been working incredibly hard to raise, fledge. @lesserspotnet.bsky.social

Ed Horncastle @edhorncastle.bsky.social · 23/05/2026
I cant believe the lesser spot chicks haven't fledged yet. The female kept calling at them to come out this morning. At one point for over 6 minutes straight. The adults are tired and want the chicks to forage for themselves. They are doing there best to avoid the lunges! @lesserspotnet.bsky.social

Female was briefly spooked tonight by a strange noise which meant she stayed a while. Not many days to go until fledging. Could be tmrw @lesserspotnet.bsky.social If this is the last I see of them this year, good luck its been a beautiful spring. #Birds

Checked lesser spot nest today for @lesserspotnet.bsky.social with help from @stuckateur.bsky.social . Looks like only two female chicks have survived out of the 4 or 5 @angusrobin.bsky.social and I saw a week ago. This despite incredible efforts from the parents. 30+ visits in an hour this morning.

Windy nest hole monitored for 95 mins 21 visits (4.5 mins per visit). 11 from F 10 from M. At least 15 times aphids were brought in. Interesting behaviour when female was reluctant to go in whilst watching a roe deer pass by. Also a bit of beak cleaning from the male. @lesserspotnet.bsky.social

A windy day on Dartmoor but in the sunny intervals I did 3 counts of Pearl Bordered fritillaries for @savebutterflies.bsky.social . The next generation were being produced. Im pretty sure I saw one being taken by a swift! Should I add that to the count? First small Pearl-bordered too.

Lesser spots doing well. Lots of aphids to feed young. Female has been staying close to the nest for long periods. Could be because she has been keeping brood warm or she was worried about the local great spot who was nearby @lesserspotnet.bsky.social #Birds
