North American Ecology (US and Canada)Speyeria callippe is a resident in the Northwestern United States and Canada (Scott 1986). Habitats are chaparral, fairly dry woodland, sagebrush and prairie hills. Host plants are herbaceous species limited to genus Viola (Violaceae). Eggs are laid haphazardly and singly, near dried up host plants (Viola), where new plants will sprout the following spring. Individuals overwinter as unfed first instar larvae. There is one flight each year with the approximate flight time June 15-Aug 15, June1-July31 in the southern part of their range (Scott 1986).
