Yes, this is a male Steatoda nobilis. They sometimes end up in trouble with us, due to wandering around looking for a mate.
The females (larger abdomens) on the other hand, tend to set home in a web & stay there, much less likely to clash with humans.
Hi Mark, Thank you for your quick reply.This spider was caught on the stair wall of my daughters house this morning. I was concerned as I was bitten on my leg 2 weeks ago by what I think was a spider that dropped down in front of me (2am in the morning, outside back door) by 5.30am my leg had swollen, started to blister and had a red ring round it. I was given antibiotics for it by my doctor. Now after 2 weeks, the huge blister burst a couple of days ago and I now have a large sore & bruised area. I cannot say for 'definate' that was a false black widow that actually bit me, as I didn't see it after it had dropped in front of me, but just wanted to confirm that these spiders ARE in our area as my daughter only lives a couple of streets away. Abingdon, Oxon. Thanks again.
