A common spider I’ve really put in the hours for over the last 2 years. After I checked a cemetery in vain less than an hour prior, who should turn up in a folded leaf right outside my door but Parasteatoda simulans?
Just 10 species to 400!

@britishspiders.bsky.social a friend found this spider indoors in Bristol. I'm absolutely stumped by it but I'm thinking maaaybe Zoropsis spinimana? That's an absolute guess though.
Was absolutely wonderful to give a talk for the British Arachnology Society AGM over the weekend! It's always wonderful getting to share the wide breadth of techniques we're using with people so passionate about these spiders!
It's Textrix time again.
Don't come across many green spiders. This one ... from below ... is quite photogenic and I think the red spot indicates a cucumber orb web spider ... Araniella cucurbitina ... on hogweed and eating something black! @britishspiders.bsky.social @norfolknats.bsky.social
The last of the 3 talks that followed our AGM was on the charismatic cave spiders (genus Meta) and was delivered by Dr Thomas Hesselberg of Oxford University. He was also elected as a new ordinary member of BAS Council.

Does anyone know what these are? I'm guessing the exoskeleton left from a molting spider?
Sorry for poor quality photos

Great trip with NRW & @naturambyth.bsky.social to look for rare fen inverts at Cors Geirch NNR. Idiocera sexguttata (Cranefly), Ground Beetle Chlaenius tristis (only UK site), Attulus caricis. @graemelyons.bsky.social @liamolds.bsky.social @dipteristsforum.bsky.social @britishspiders.bsky.social
A tiny, busy female cobweb Spider, Anelosimus vittatus, we think, moving her silk-covered egg sac to her chosen place... @britishspiders.bsky.social

Back at Kenfig Burrows today with Christian Owen, searching for some of the reserve's rarest invertebrates for NRW.
We managed to find 3 target species, including the false widow spider Steatoda albomaculata. We found two individuals — a male and female (in the photo). @britishspiders.bsky.social

The second of the talks following our AGM was given by Rosy Christopher @envirosyment.bsky.social of Newcastle University. Titled Friend, Foe or Freeloader, it considered the relationship between Flower Crab Spiders (Misumena vatia) and the flowers it sits on. Available at youtu.be/Gada2vNhF7w?...
