North American Ecology (US and Canada)Resident throughout much of central and eastern North America (Scott 1986). Habitats are wooded areas. Host plants can be herbs, vines, shrubs or trees, with known hosts in many families. Eggs are laid on the host plant flower buds singly. Larvae are tended by ants. Individuals overwinter as pupae. There are one or two flights each year depending on location. Flights occur between Feb 1 and Nov 30 in the more southern parts of the range, and often between May 15-Aug 15 in the most northern regions (Scott 1986). Treated as a subspecies of C. argiolus by some (Scott 1986).
