Comments & ID Thoughts

Found this in a child's play area. Is it dangerous? Almost looks like a black widow. Did have a design on back but not red...more of a tan color.

I could be wrong, It might be a black lace-weaver. It does not normally bite, when it does, it’s reported to be quite painful, with slight nausea. Just let it back outdoors and your kids will be safe. :#

No, that species is found in the northeast, not CA.
