We found this guy on the ceiling inside today. We live by Lake Erie in Ohio so we see a lot of large spiders, but this one looks different than most we encounter. It's was about the size of a quarter (~ 25 mm), and the abdomen was iridescent.

  • $\begingroup$ Not a spider person but I did find this useful summary of commonly encountered Pennsylvania spiders, a few of which are similar-looking. $\endgroup$ – InsectSinger Jun 26 '18 at 0:24
  • $\begingroup$ It looks to me like a false widow spider, Steatoda grossa. It would be helpful if you could find one in their web so I could see what its web looks like. $\endgroup$ – Joseph Dec 1 '18 at 4:02
