Recorded from all sites; very common except at Castle Peak, where it may be only a stray. This skipper is only slightly less intolerant of civilization than O. agricola, but it occurs in a vast array of habitats, including chaparral, riparian woodland, montane coniferous forest and shrub-steppe. It flies in the second half of the season, beginning just when O. agricola ends. At low elevation it appears to have two back-to-back broods, flying from late June or early July through October. At washington and above it has only one.
