North American Ecology (US and Canada)Speyeria egleis is resident to the northwestern United States (Scott 1986). Habitats are forest openings, but usually on exposed rocky ridges from Calif. to Washington. Host plants are herbaceous, and restricted to several species of 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 late June-Aug. 15 (Scott 1986).
