found crawling around the the kitchen.
No interactions present.
Ooops just realised I miss spelt the name, should be Steatoda, not Steatota! hee hee.
They do seem to be becoming very common, at least in the south, wonder how long it will be till they get as far north as lpearce in north of scotland.
Yes, they've certainly expanded their range since the CEH's 2002 Atlas which shows very few records. Very common under the stairs in our old house near Eastleigh/Southampton...
Will they really bite? Are they venomous?
wiki says "Some members of this genus do have bites which are medically significant in humans (such as S. grossa and S. nobilis), however bites by Steatoda species generally do not have any long-lasting effects."
Not really sure what medically significant means, perhaps dangerous to young or infirm people?
These spiders are not aggressive, but can bite if provoked (e.g. if they get trapped in clothing), and as with many invertebrate bites different people seem to react more or less severely. If you're sensitive to them the bite can be quite severe. More information on the Natural History Museum website:
(Incidentally, this site provides a good demonstration of the usefulness of scientific names: it indexes three different species under the name "False widow spider" - to see the info for Steatoda nobilis you need "Report 2".)

Thanks for the link I'll check it out. But will avoid handling this one for the time being.
As the person who first discovered this species in UK, I confirm the ID. Whilst looking through these pictures this evening I collared a male on my wall!
Congratulations on the discovery Dick! Would you mind clicking on the "I agree" link in the identification box, above? That helps us keep track of the confirmed IDs on iSpot.
All the individuals of this species I'd found previously were indoors around the flats but just seen one on a north east facing window frame outside and appears to have been there for a long time, possibly overwintering somewhere round the frame with the help of warmth from the house.
Does anyone know what temperatures this species will tolerate, is it temperature that has kept the species out previously or were there other factors?
