I haven't worked through this key, but it is the only CA species I see:

"Only a few raids have been observed, but from unpublished observations by Les Greenberg (U. C. Riverside, pers. comm.) and Geoff Trager (then a student at UC Santa Barbara, pers. comm.), we know that the raids take place in early to mid summer, in the latter half of the afternoon. The raiding season may begin and end earlier than that of species from colder, summer-rainy climates."
