North American Ecology (US and Canada)Resident in Alaska and western Canada (Scott 1986). Habitats are TAIGA CLEARINGS, TALUS SLOPES. Host plants are usually herbaceous with most known hosts largely restricted to a few species in one family, Cruciferae. Eggs are laid on the host plant singly. Individuals overwinter as pupae. There is one flight each year with the approximate flight time JUN1-JUL31 depending on latitude (Scott 1986).
