Plus 16 more recorded only rarely (fewer than 10 verified sightings). Counts from verified iNaturalist observations.

The Koch's Wolf Spider (Alopecosa kochi) is the most commonly recorded, with 7,188 verified observations, about 60% of all wolf spiders reported in California. If you spot a wolf spider here, it is statistically most likely to be this one.

California also hosts less common wolf spiders such as Varacosa gosiuta, Pirate Otter Spider and Geolycosa gosoga, each recorded fewer than 100 times. These are the species worth a second look when you are out, since a sighting is more notable.
