Comments & ID Thoughts

Found in corner of garage behind old piece of loose drywall. Is it a black widow? Or Steatada Borealis?

Hi, welcome to Spider ID. 🙂 This is a Triangulate Cobweb Weaver, Steatoda triangulosa.

The pattern on the abdomen is quite different. S. borealis is more of a line whereas this has a series of triangles.
