Common to abundant at all but the Sacramento Valley sites and Castle Peak, where near its altitudinal limit. Formerly occurred at North Sacramento, but now extinct (?). A devout mud puddler (males only); both sexes visit many flowers, especially Ceanothus and California Buckeye, both of which are hosts of the larvae. There is little variation in our area; second brood specimens are larger and brighter. Two broods in the foothills (January-April, May-July) and one at and above 5000' (May-July).
