Comments & ID Thoughts

Not sure who this guy is. Legs on front are longer, red dots on back, about the size of a dime including his legs. Some type of Cobweb spider perhaps? Ideas?

If it has red dots, please be mindful, as this is likely Latrodectus or Black Widow which are very medically significant. If bitten, please go to the doctor immediately.

Based on location, and series of dots, perhaps Latrodectus variolus.

Hi, welcome to Spider ID. 🙂 This looks like a Triangulate Cobweb Weaver, Steatoda triangulosa. The spots on the back don’t appear too red to me. Widows have more robust legs. I do agree with Disco though that if you see a black cobweb spider with red spots it’s a good idea to be mindful that a Widow (Latrodectus) is a possibility.
