Canton, 
Just learning about spider types and realize some are dangerous. Does anyone know what this is, found in my front yard. Wondering whether dangerous to people and pets? Thank you
Hi, and welcome to the site. Your spider looks to be one of the trap door spiders, your location,likely Bothriocyrtum californicum species, California trapdoor spider. Nice find for a budding arachnologist. These are not considered dangerous, but like nearly all spiders, they are venomous. A bite may cause pain and possibly some swelling, but because every bodies immune system is different, the outcome of a bite can’t be predicted. Dangerous spiders are considered medically significant where bites might cause reaction or injury requiring medical intervention. The good news is in California, only the western black widow is considered dangerous. Most… Read more »
This is not a Mygalomorph. Also, “there are several other species of recluse spiders that can occur in southern areas of California and that can cause similar medical concerns” – Rick Vetter

I see my monitor has failed me again and blew another ID. A false tarantula, Calisoga spp. Bugguide needs some correcting also.

I intentionally did not indicate other violin spiders found in California,2 reasons./zero specimens found in coastal counties,//zero report of bites or injury. Again, my bad.
Bear with me, I am on a poor laptop and trying to be asset to the site.
Thanks for correcting me. > If this is not Calisoga, I must know what it is.
BugGuide’s ID appears accurate and was determined by a professional arachnoligist, Marshal Hedin.
Then so much for common names. Not arguing the species here.
Hi, welcome to Spider ID. 🙂 This looks like a Hacklemesh Weaver (Amaurobiidae). There are a lot of species in both Amaurobius and Callobius native to CA that I have yet to see confirmed images of. I’m not sure which this would be. Like most spiders they have venom but are not considered to be of medical significance, everyone’s immune system is different though.

I agree with Amaurobiidae
