Hi, this is a Wolf Spider (Lycosidae), looks like Schizocosa mccooki.

How are you able to differentiate from S. avida?

ItsyBitsy

Range. For CA I think it’s between S. mccooki and S. maxima.

For some reason I thought I had chosen Wyoming in the category of spiders, I completely missed the location being California

ItsyBitsy

Yeah, where the range overlaps things get too confusing and I usually go with genus. I haven’t pinpointed a reliable way to tell them apart from an image like this yet.

Nmstalick307

Neither have I, which is why I was curious, I believe there are differences on the ventral
