North American Ecology (US and Canada)Speyeria aphrodite is resident to northeastern United States and much of southern Canada, with migration in southern parts of the range (Scott 1986). Habitats are dry transition to Canadian zone brushland or open woods, tall prairie. Host plants are herbaceous species restricted to 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-Sept. 15. (Scott 1986).
