B spider1 - Steatoda borealis - Male
Brighton, Livingston County, Michigan, USA
October 13, 2005
Size: about 1/2" with legs
Wife found in rarely used drinking glass. Female (larger) fell down sink drain before I could get a picture. Cobweb-style web in the glass. Abdomen about 1/8" long. I don't have the greatest camera for close ups; on it's back there is a light brown stripe along the abdomen(near to body) and another vertical down the abdomen (sort of like a 'T'). Some light brown also on the underside of the abdomen.
Any idea what it is?

Steatoda
Maybe a male Steatoda sp.?

I agree.
I would say an adult male S. borealis.
