Cobweb Spider? ID

[Tarantula155]

Caught this female spider in the basement. I think it's a cobweb spider, not too sure though. If it is, what species is it?

One more thing, can someone tell me how long these spiders live or can live?

 

[Silberrücken]

Steatoda triangulosa.

 

[Tarantula155]

Steatoda triangulosa.

Lifespans?

 

[Ciphor]

12-24 months. 3 years I'm sure if you did it right.

Actually, like many theridiids, they can live quite long.

S. grossa can live to be over 5 years, i know this for sure, because one in my room had the same corner to web in year after year, until she mated, then she died soon after, which was a few months after her 5th year.

She was HUGE, too! Before i knew of this specimen, i thought they didn't get all that large.

Actually** most cobweb spiders do not live over 2 years. Steatoda grossa is an exception to this rule. In general the genres of Steatoda & Latrodectus have the capability to live 3-4 years however they seldom do. S. grossa has been recorded up to 6 years and is the longest living cobweb spider.
