Steatoda grossa
(False Black Widow)

Comments & ID Thoughts

Found this spider in our kids bathtub. We have a lot of spiders around including black widows- so just want to be sure it’s not that.

Definitely a black spider. From tip of legs to tip of opposite legs is about the size of a nickel.

It also did a pretty impressive jump using its thread to the top of the kids toy basket from the bottom of the tub.
