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.

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.

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

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

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

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.

Important change to Phaonia tuguriorum & P. scutellata in the UK checklist update in DD. Hopefully I've understood and the below is correct meaning the very common species with pale bases to the palpi is now P. signata and P. tuguriorum is now the name for the rare species
