Steatoda borealis

Comments & ID Thoughts

The biggest ones were very smooth and black like black widows, but with this weird geometric black and rust colored shape underneath the belly. It does not look like the brown widow photos I looked at, the spider is very black. These were in an outhouse and in webs. They seemed to be ok being near each other. There were a handful of 1/4” sized larger spiders in corners with webs catching flies and 100’s of smaller babies all over. What the heck are they?
