Hi, this is a Widow. Given the condition it’s in I’m not sure if it’s a dark Brown Widow (L. geometricus) or a Western Black Widow (L. hesperus). Both can have striped legs like that.

Also for future reference Brown Widows have distinctive spiky egg sacs:

Edit: Leaning Brown Widow, I’d need to spend some more time comparing the two.

It had yellow spots on top of the belly. 2 or 4 cant recall. And it wasnt black like the defenetly black widow of the oyher day. I refer to the photo of the link posted of the yellow dots and stipes. This seem to have had pale yellow dots buy no stripes. Widows are with yellow spots too?
