- February arrives and the Gadwall are getting frisky...
- Little Egret H3 still at Kilnwick Percy this morning...has been a regular by the lakes the last few weeks. A local bird from the @ldvnnr.bsky.social. @ynuorg.bsky.social @yorkswildlife.bsky.social
- Scoured all the sunlit barriers, fence posts, benches and vegetation at #BemptonCliffs for Diptera on Monday, but not a winter-active fly to be seen, not even a Calliphora. And no flat-flies on this Kestrel either! Hard times for dipterists... 😄 @ynuorg.bsky.social @dipteristsforum.bsky.social
- My second invertebrate record of the new year at Cali Heath @yorkswildlife.bsky.social reserve this am. Once very scarce, Corizus hyoscyami is now a regular find in East Yorkshire throughout the year. @ynuorg.bsky.social
- My first invertebrate record for 2026...Boreus hyemalis (Snow Flea) at Cali Heath @yorkswildlife.bsky.social reserve this am. Exciting to think what else might turn up this year. 😀 @ynuorg.bsky.social #mecoptera #ukwildlife
- Ravens very active and vocal up on the Yorkshire Wolds this morning...surprised to see so many, but it's a while since I've been up there in winter. @yorkbirding.bsky.social
- A flightless female moth...Pale Brindled Beauty...at Cali Heath @yorkswildlife.bsky.social reserve this morning. Only 4 degrees, but bright and plenty of insects around. @ynuorg.bsky.social #moths
- Thinking this is Diaea dorsata, which I am sweeping/seeing repeatedly at Allerthorpe Common in East Yorkshire at the moment, so it must be well-established up here now? @ynuorg.bsky.social @yorkswildlife.bsky.social @ecology-digest.bsky.social @britishspiders.bsky.social
- A dry, warm (10 degrees) day brought out quite a variety of invertebrates at Cali Heath @yorkswildlife.bsky.social reserve this morning. Just a few here...Pisaura, Curculio, Brachypera and Notostira perhaps. @ynuorg.bsky.social #ukwildlife
- What a fantastic record!
- A dipterist's dipteron, the elusive Borboropsis puberula. The only member of the family in the UK. Restricted to the Scottish Highlands. This one from Ben Lawers is probably the 7th UK record. #Diptera #Entomology @dipteristsforum.bsky.social

- Lots of Earwig activity at Cali Heath @yorkswildlife.bsky.social reserve today, with individuals burrowing into the sandy turf, leaving just the formidable pincers exposed. Common enough, but actually rather extraordinary things. @ynuorg.bsky.social #ukwildlife
- My first Snow Flea (Boreus hyemalis) of the winter at Cali Heath @yorkswildlife.bsky.social reserve today. Nice of her to pose out in the open on a fallen leaf, so didn't need to spend hours waiting for one to emerge from the Polytrichum moss! @ynuorg.bsky.social #Mecoptera #Boreidae #ukwildlife
- Not too many birds at Bempton Cliffs this morning, so had a look at flies on the fence atop the cliffs. Nice variety, with muscids, calliphorids, anisopodids, heleomyzids, anthomyiids, coelopids and more. IDs on the photos. @rspbengland.bsky.social @dipteristsforum.bsky.social @ynuorg.bsky.social
- As good as it gets...
- Gymnomus caesius (Heleomyzidae)...stunning orange and grey, spiny-winged fly of woodland, with males often holding territory on logs. All records gratefully received on iRecord. 🙂 Allerthorpe Common, East Yorkshire today. @dipteristsforum.bsky.social #heleomyzidae dipterists.org.uk/heleomyzid-s...
- Thaumatomyia notata, the Yellow Swarming Fly doing exactly that at Allerthorpe Common in East Yorkshire....10,000s of them on pine trunks, and particularly interested in this Hairy Shieldbug. @yorkswildlife.bsky.social @ynuorg.bsky.social @dipteristsforum.bsky.social
- Reposted by Ian AndrewsGonatherus planiceps female #Scathophagidae. A uncommonly collected, spring-flying, species of upland flushes and other wet habitats in the mountains. This one from Beinn Ghlas in the Ben Lawers NNR this May. #Diptera #Entomology @dipteristsforum.bsky.social
- A few fungi-loving autumn flies from three different families at Cali Heath @yorkswildlife.bsky.social reserve yesterday. Names on ALT. @ynuorg.bsky.social @dipteristsforum.bsky.social
- Finally some fungi appearing locally in East Yorkshire, and with those come the fungus-breeding, spiny-winged heleomyzid flies, like this gorgeous Suillia notata at Cali Heath @yorkswildlife.bsky.social reserve. #heleomyzidae @ynuorg.bsky.social @dipteristsforum.bsky.social

- Locust Blowflies (Stomorhina lunata) continue to arrive...third of the summer at Cali Heath @yorkswildlife.bsky.social reserve today. It's been a bumper year for grasshoppers and crickets locally, so surely some must be breeding in those...or are they all migrants? 🤔 @dipteristsforum.bsky.social
- Sallow Kitten on Sallow (!) at Cali Heath @yorkswildlife.bsky.social reserve today. What a stunning caterpillar. 🙂
- The Copper Peacock (Elaphrus cupreus) running around on mud at pond edge on Allerthorpe Common @yorkswildlife.bsky.social reserve this morning. #carabidae #ukwildlife
- Athalia rosae (Turnip Sawfly) generally seems to be having an incredible year...huge numbers everywhere. This one not quite so much...any ID possible on the spider? Cali Heath @yorkswildlife.bsky.social reserve yesterday. #yorkshiresawflies @britishspiders.bsky.social
