North American Ecology (US and Canada)

Ochlodes sylvanoides is a year-round resident in southwestern British Columbia, Canada, throughout much of the northwestern United States and south through California and into northern Baja, Mexico (Scott 1986). Habitats are chaparral, sagebrush and woodland. Host plants are grasses of multiple species. Individuals overwinter as first instar larvae. There is one flight each year, mostly late July-Aug.31. with two flights in the California central valley between late June-Oct.31, and several flights between April.1-Aug.31 on Santa Cruz Island (Scott 1986).
