It's not the greatest photograph but I think this can only be one or two spiders, both 'False Widows' either Steatoda grossa or my favorite in this case Steatoda noblis. Both can give a nip but as with most spiders they have to be thouroughly provoked. Hours of really personal name calling has little effect as does criticism of their football team (Steatoda support A.F.C. Bournemouth apart from S.bipunctata who support Millwall ).
Ah, you see that the Steatoda cousins lived on the South West coast for years before moving Northwards, so Bournemouth AFC is in their blood. I'd appreciate it as well if we could keep mentions of the Red Scum to a minimum.
