Picture of unidentified spider

Comments & ID Thoughts

I saw a smaller spider with similar markings which was much smaller and sac not as round. Could it be a female brown widow?

Hi, pretty sure this is Steatoda triangulosa, a triangulate cobweaver. They are in the same Family as brown widows. The smaller one sounds like a male and this one looks female.
