Was happy to find this Neobisium simile 🙂 in the 1st vac sample - even happier when the behemoth dropped onto the tray a few sucks later. Adult is twice as big as a carcinoides (a single specimen of this was also in the sample). @britishspiders.bsky.social @pseudoliam.bsky.social @sewbrec.org.uk

It truth it probably occurs in every sizable UK town now, just under-recorded. iRecord shows how ubiquitous it is in lowland England. @britishspiders.bsky.social Visit irecord.org.uk/enter-srs-re... to submit records to the Spider Recording Scheme.

You were right Jess! The Sedge bed did produce something interesting - 7 female Entelecara omissa new to Cheshire. A nice fenland species. But still debating whether it was worth missing out on ice cream for this tiddler 😆 @britishspiders.bsky.social @tylanberry.bsky.social @graemelyons.bsky.social
