North American Ecology (US and Canada)

Boloria freija is a resident across Canada, with several smaller populations in the central portion of the United States (Scott 1986), and ranges to Scandinavia, Siberia and Japan. Habitats are Canadian zone bogs and valley forest openings to arctic/alpine tundra valleys. Host plants are shrubs and herbs with species from family Ericaceae, Empetraceae, and Rosaceae. Eggs are laid haphazardly on or near the host plant as single eggs. Individuals overwinter as fourth-instar larvae. There is one flight each year with the approximate flight time May15-July15 depending on latitude (Scott 1986).
