I agree with you: it looks like Steatoda grossa. It's very similar to the photos on this page, especially the eigth photo from the top down. That is a female, and the one just above it is a male. When the pedipals are visible, I can tell males apart from females, but I can't see them well enough in your photo. Maybe an expert could confirm this?
Thank you for posting the image.
I think S. bipunctata. I don't see the ligher band at the base of the abdomen, but such dark body and legs striped with red are bipunctata, as far as I know.
Bombuslucorum will no doubt shed light on these.
I was hoping someone would be able to confirm what the spider is in these pictures? I think it might be S. Grossa female, from what i've seen on the internet? I have a 2 year old daughter and an 11 week old - do these spiders pose any risk to young children?
I found a spider in our wasing machine the other day and have been trying to identify it from the pictures on the internet. It could be Steatoda grossa, or Black Widow, quite how that managed to get into the washing machine i don't know. I have taken some pictures (attached) and I am hoping someone can help identify it, bearing in mind that it has been through a wash cycle!!
