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.
Thank you, how do you differentiate between this and S. Borealis?
The pattern on the abdomen is quite different. S. borealis is more of a line whereas this has a series of triangles.
