North American Ecology (US and Canada)
Mostly migratory in North America (Scott 1986). Habitats are OPEN AREAS AND ROADSIDES. Host plants are usually herbaceous with most known hosts largely restricted to a few species in one family, COMPOSITAE. Eggs are laid on the host plant singly. There are multiple flights each year with the approximate flight time MAR1-DEC31 depending on latitude (Scott 1986).
