Leptometopa latipes (Milichiidae)...2-3mm freeloader fly. Seem to be few records nationally, but conservative estimate of 5000 today at Bempton Cliffs, where I suspect they associate with seabird guano. They were all over the cliff edge hand rails! @dipteristsforum.bsky.social @ynuorg.bsky.social

Huge congrats to @jasboparai.bsky.social on what I'm sure will be an essential book for an underworked group. But absolute shame on CABI & @royentsoc.bsky.social for their new pricing. £125 for a 25-species handbook is unreasonable and will prevent it from reaching its deserved audience.

Pleased to have been told by the publishers this will be available for release from the 26th June (ebook 19th). Many thanks to the reviewers, editors and others who gave their time and expertise towards getting this finalised. I Hope readers find it useful. tinyurl.com/5br4skkv #Ichneumomonidae

Dead but still looking good - the seeds of Medicago praecox (Early Medick) seen today at Lee-on-the-Solent, a known site for this very rare non-native. plantatlas2020.org/atlas/2cd4p9... @bsbibotany.bsky.social

A couple from this weekend. The uncommon neophyte Melilotus indicus (Small Melilot) on a roundabout near Portsmouth and the extremely rare Ranunculus ophioglossifolius (Adder's-tongue Spearwort) in Gloucestershire. @bsbibotany.bsky.social

I built a thing for me and thought it might be useful for others. It's a set of guides, 20 at the moment, to help with my rubbish memory when doing ids in the field. Everything is cached on your device so works in low signal areas. naturesfieldbook.com

Turritis glabra (Tower Mustard) near Kingsley, Hants. A very nice plant. Visit inspired by @trisnorton.bsky.social post the other day.

After months of work my Norfolk Pseudoscorpion guide for @norfolknats.bsky.social is now on the website free to see/download. Covers 20 species recorded in Norfolk so hopefully useful for other areas of UK. norfolknaturalists.org.uk/wp/wp-conten...

A long-held birding dream realised last week with several Algerian Nuthatch (Sitta ledanti) in Algerian Oak (Quercus canariensis) woodland, Tamentout-forest, Sétif Province. Thanks to Karim Haddad & Mehdi Chetibi for guiding.

A lovely little frog-faced Brachydeutera fly (Ephydridae), hanging out on some standing water. Texas.

Primula elatior (Oxlip) early on a damp morning in Buff Wood a couple of weeks back @bsbibotany.bsky.social

Limnellia surturi...a rather smart, rather little shore fly (Ephydridae) on sand outside a rabbit burrow at Cali Heath @yorkswildlife.bsky.social reserve yesterday. Looks to be a new VC record. #Ephydridae #shoreflies @dipteristsforum.bsky.social @ynuorg.bsky.social

A nice little Chlorops from Waitby Greenriggs Nature Reserve, Cumbria, collected on the @dipteristsforum.bsky.social summer 2024 meeting. Awaiting confirmation but seems to be C. geminatus, a species not on the UK list

Very exciting that this book is nearly here and even more so that among all the flies I'm also featured (tiny and blurry in the top left of the pic)

Very exciting news for all Sphaeroceridae fans

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

I'm speaking on #Chloropidae, trying to make a difficult and neglected group a little more accessible via a group-sourced Flickr photo library. Also looking forward to hearing the other speakers. www.flickr.com/groups/chlor...

I'm currently updating and making corrections to the Ephydridae key prepared for the @dipteristsforum.bsky.social workshop. Please let me know if you've noticed any errors or anything that might need updating. Comments, DM or email to sjthomasbotanyATgmail.com please. #Diptera #entomology

New #GBRedList for vascular plants is published today by a team led by @bsbibotany.bsky.social with partners @naturalengland.bsky.social @ukceh.bsky.social @naturescot.bsky.social @natreswales.bsky.social @nhm-london.bsky.social @plantlifeintl.bsky.social @rbgkew.bsky.social @thebotanics.bsky.social

Empis digramma female #Empididae. A distinctive pale yellow species with short bristles and two stripes on the scutum. Frequent in the north of the UK. #Diptera #Entomology #insectphotography #inverts #bugsky #macro

The very small #Chloropidae Pseudopachychaeta ruficeps swept this spring from alpine sedge flushes, Beinn Ghlas, Ben Lawers NNR. This species develops in the inflorescences of Eriophorum (Cottongrass) species. #Diptera #Entomology @dipteristsforum.bsky.social

Gonatherus 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

It's not asylum seekers who jack up rents, undermine the NHS, hold down wages and keep people insecure. It's capital. The role of the far right is to shift the blame for decades of economic attacks by the rich and powerful onto powerless people who have only just arrived here.

However you arrive in the UK you are welcome. People who are 'concerned about immigration' are racist. The government is at fault for poverty. Stop punching down.

Ranunculus x levenensis with parent spp R. reptans Creeping Spearwort & R. flammula Lesser Spearwort on a Cumbrian lake shore. The hybrid has larger flowers & broader lamina than reptans with linear leaves. R. reptans has few GB locations, often ephemeral being introduced from the arctic by birds

Rock sea-lavenders from the Afon Crigyll Estuary Ynys Môn: Limonium recurvum subsp. crigyllensis (with rough scape) described in 2022 by Ivor Rees and only know from this site where it grows with the more widespread L. procerum (smooth scape). @bsbibotany.bsky.social #wildflowerhour

Hypopitys monotropa (Yellow Bird’s-nest) from an evening woodland walk. This is subspecies hypophegea which is completely glabrous, often delicate, yellowish with fewer flowers. Now is the time to check the subsp. ID of your local populations with Fred Rumsey's @bsbibotany.bsky.social News key.

Scotland trip started on Skye: Koenigia islandica (Iceland-purslane) only just germinating and the weather too bad for Arabis alpina on the Cuillins. However, Ligusticum scoticum (Scots Lovage) was looking lovely at Armadale. 1/5 @bsbiscotland.bsky.social @bsbibotany.bsky.social #wildflowerhour

Just back from a mostly productive botany trip around western Scotland, still need to edit the plant photos so here's a delightful male Snow Bunting singing on the summit of Ben Nevis in the evening sunshine.

Received the pdf of my paper adding Philotelma parvum to the UK list in the upcoming issue of Dipterists Digest. A rather obscure little Ephydridae (shore fly) collected from the New Forest, emphasising again the importance of New Forest mires for rare Diptera drive.google.com/file/d/1FCwH...

Very unexpected & rare: Anticheta obliviosa female #Sciomyzidae from saltmarsh on Hayling Island, Hampshire. Previously known in the UK from fens around Huntingdon and singles from Cheshire and Yorkshire - all inland. Nice find for a quick evening sweep #ento #diptera @dipteristsforum.bsky.social

Glenanthe sp. female from Hayling Island the other day. A very small saltmarsh #Ephydridae with distinctively 'upside down pear' shaped eyes. Likely G. ripicola but can't rule out G. fuscinervis without a male. #Diptera #ento #macro @dipteristsforum.bsky.social

Almost forgot #WorldRobberFlyDay but luckily reminded by @flygirlnhm.bsky.social. Here's the puparium of Laphria flava (Bumblebee Robberfly) collected from a pine log in Abernethy Forest a few years back. @dipteristsforum.bsky.social #diptera #ento #macro

Chlorops varsoviensis a pNationally Scarce #Chloropidae of upland marshy areas. Now added to the (slowly) growing Chloropidae UK Flickr group. Please add any relevant identified photos or message me and I can help add them www.flickr.com/groups/14873... #diptera #ento @dipteristsforum.bsky.social

Rhamphomyia maculipennis, a costal #Empididae with two dark marks on the wing in females, from Hayling Island today. #diptera #ento @dipteristsforum.bsky.social

Swift moth caterpillar-eye view of a female Alomya debellator wasp - a specialist parasitoid of root-feeding Hepialidae which it hunts in the caterpillar's underground burrow.

Some exciting new ID webinars on tricky plant taxa I'm organising over the next few months

A few pics of cranefly male terminalia from Ben Lawers last summer. Part of an occasional effort to produce decent images for these as I often find the line drawings in the book difficult to interpret.

Scoliocentra flavotestacea female #Heleomyzidae from Creag an Lochain, Ben Lawers last summer. An uncommon species according to @suillia.bsky.social great ID resources available here: dipterists.org.uk/heleomyzid-s...

We're proud to be 1 of 10 UKTEPoP partners who today published a joint statement pledging our commitment to diversity, equity & inclusion in UK species monitoring schemes: jncc.gov.uk/our-work/ukt... We need to better understand how biodiversity loss is impacting under-recorded areas & communities.

Flip-Flop taking his #NewYearPlantHunt 2025 Support Team role very seriously this morning - at the ready to identify any tricky plant finds @bsbibotany.bsky.social

It seems like there are a few issues with Dryopteris names on PSL @panspecieslisting.bsky.social. Nothing is solid with this group but see attached from Fred the other month. Unless the current approach is based on expert input I think some need to be removed, see comments in alt text.

I wish this didn't keep coming up in my feed, getting more and more tempted. I don't have the other volumes but small staphs are almost honorary flies, they turn up a lot in my samples and I generally haven't been able to do anything with them up until now

'Refound' by Jac and I without realising that it hadn't been recorded for nine years, can't really take credit given someone had put protective sticks around it before we turned up.

Apparently #BlackFlyDay so here is one - Lonchaea fugax a common lance-fly from the other year #invertebrates #entomology #diptera

Steven Falk has just added six more British Muscidae genera to his Flickr site: Limnospila, Macrorchis, Orchisia, Pseudolimnophora, Schoenomyza and Spanochaeta flickr.com/photos/63075.... Images & detailed accounts for each species. Biodiversity! Look at that colourful Schoenomyza litorella head!

One from the back catalogue: Gonia picea an early spring #Tachinidae with a superbly bristly face

Nice to finally see Erigeron bonariensis in the UK and complete my Erigeron composite. Thanks to @trisnorton.bsky.social for showing me the plants

I've updated all of the #Hieracium on my website www.vascularplants.co.uk/asteraceae-d... there are 150 species photographed. Here are a few 2024 highlights from my first ever #hawkweed trip to Scotland Hieracium basicrinum, H cuspidens, H pseudoanglicum, H laetificum
