North American Ecology (US and Canada)

Boloria selene is a resident of much of Canada and across the northern United states, with a separate population in eastern WA, and one in Colorado/New Mexico (Scott 1986). Habitats are northern upper Austral to Hudsonian zone moist meadows, bogs and spring-fed meadows (even in shortgrass prairie). Host plants are herbaceous species, in North America are restricted to genus Viola (Violaceae). Eggs are laid haphazardly near the host plant, as single eggs. Individuals overwinter as second to fourth-instar larvae. There is a variable number of flights each year depending on latitude with approximate flight times between May 15-early Sept. (Scott 1986).
