Tiny spider (length 4.5mm) jumping about on the wall
No interactions present.
I reckon you're ID is correct but its current name on both the British Arachnological Society checklist and World Spider Catalog is Pseudeuophrys lanigera
That explains why the NBN link didn't come up even though the name was on the ispot drop down list. No records for this species yet on the BRERC database although it has been recorded in North Somerset and also made an appearance in the BRERC office last year.
