@britishspiders.bsky.social @tylanberry.bsky.social @graemelyons.bsky.social Feels like the start of Autumn - Linyphiidae season. A nice Small-horned Walckenaer (Walckenaeria corniculans) from the weekend, to start things off

@britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk A quick stop-off in Wales, to find a spider that I've yet to see in England. It always surprises me just how well such a big spider can 'hide in plain sight' on bare stone Arctosa cinerea is always a sight to behold

@britishspiders.bsky.social @cofnod.org.uk @tylanberry.bsky.social More spiders on the move. Enoplognatha mordax, moving inland from the coast, a first for me and maybe VC24 too. Meanwhile, Theridion pinastri and Macaroeris are busy establishing themselves in the south of the county

An insect body part, recovered from an 80cm deep peat core in a mid-Norfolk fen. It seems quite a distinctive shape, so somebody may even know what species it is from. Let me know if you do! 1.3mm.

@britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk @bucksinvertgroup.bsky.social A spider that's neither rare nor particularly scarce. It has, however, taken me an awful long time and many fruitless searches to finally find Pachygnatha listeri

@britishspiders.bsky.social Very happy to still be finding new spiders as we approach the end of the year: Gnaphosa leporina has been high on my wanted list, since Lawrence Bee found it locally during a survey in 2019. Thanatus striatus, is, I believe, a first for Buckinghamshire,

Some finds from recent garden centre visits. It's exciting to see exotic or nationally scarce species and most of these are confined to the environment they find themselves in and won't establish themselves in the wild, you do have to wonder whether we need increased biosecurity measures #spiders
