I’m a bit of an amateur arachnologist, and as such a lot of my friends text me pics for identification regularly. I usually can get them at least a Genus within moments, but a friend of a friend sent me a pic that has me a little stumped. It’s a female grey spider, no web visible, with some interesting protrusions on her back. I tried to do some research, but I keep coming up with blanks. What is she? I’d love to know! She was found in Northern California, we live in San Francisco and I believe her friend found the little lady in the east bay.

Dear Luke,
This is an Orbweaver in the family Araneidae, and we believe it might be a Cat-Faced Spider,
Araneus gemmoides.  You can see the resemblance to this individual posted to BugGuide.
