Steatoda paykulliana. She’s not medically dangerous to people or pets. a common name for her is a False Widow. They are good indoor spiders, they eat many kinds of insects that are considered pests.

This spider more closely matches Steatoda Triangulosa to me. The triangular markings on Steatoda Paykulliana are often smoother, while on Steatoda Triangulosa they appear more mottled (Almost like peened silver?). That’s how I tell the difference at least 🙂

I get desperate to observe spiders doing stuff in January!

BugGuide volunteers have been very kind in teaching me things. Feel free to debate my identifications or other statements. I’ve only done this about 3 years and only had routine oversight of my answers for about my first year. I… Read more »

It’s about the same in Michigan! I recently joined BugGuide, currently I’m lurking to get a feel for the site. I find wolf spiders tricky too, they are all way to similar for me to distinguish well.
