North American Ecology (US and Canada)
Speyeria cybele is a resident across the central and northern United States and Southern Canada (Scott 1986). Habitats are transition to Canadian zone moist deciduous woods and moist meadows. Host plants are herbaceous and restricted to several species in genus Viola (Violaceae). Eggs are laid haphazardly, near the host plant, and singly. Individuals overwinter as unfed first-instar larvae. There is one flight each year with the approximate flight time June 15-Sept 15, sometimes starting May 1 in the east, and mostly July1-Aug 31 in the west (Scott 1986).
