What does "rarity" mean anyway? This Sphagnum-fringed pool in Westmorland yielded 1 Lophomma punctatum, 2 Bathyphantes gracilis, 1 Mecynargus morulus, but 'only' 39 Semljicola caliginosus (new hectad record too & commonest 🕷️in sample🤔) @britishspiders.bsky.social @ecology-digest.bsky.social

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.

A quick site recce to an Anglesey Fen (with no previous spider records), seemed like a good excuse to take the Vac. NR Attulus caricis at a new site. Had to work hard to find wet Schoenus here!! @britishspiders.bsky.social @graemelyons.bsky.social @tylanberry.bsky.social @chalkspring.bsky.social

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

Cofnod #RecordOfTheWeek is this immature male Marpissa muscosa Jumping Spider. Only the 2nd Welsh record and new to VC49. Recorded by KevinH on the Llyn. Presumably hitchhiked in from England on farm equipment or similar. @britishspiders.bsky.social @sewbrec.org.uk @wwbic1.bsky.social

Who ate all the flies? An abandoned room occupied by Eratigena with a +1 m web - obviously pigging out on Cluster Flies. Sadly the spider was long departed (presumably a male that matured and left). @britishspiders.bsky.social
