Camponotus in Coastal Southern California fly at night. At higher elevation areas they will fly in the earlier evening.
However, no matter when they fly, it is best to look at night, as that is when they all come out to search for founding chambers, or continue digging them.

Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies.
However, I went back to the Sierras, and restarted my collection, which is now as follows:
Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).
