Speyeria coronis is a resident in the northwestern United States (Scott 1986). Habitats are transition to Canadian zone chaparral, sagbrush and conifer woodland. Host plants are herbaceous, restricted to several species within genus Viola (Violaceae). Eggs are laid haphazardly, near the host plant, singly. Individuals overwinter as unfed first instar larvae. There is one flight each year with the approximate flight time June 1- early Sep. (Scott 1986).
