North American Ecology (US and Canada)

Polites themistocles is a year-round resident in the eastern United States and southeastern Canada, into Washington state in the north, and though parts of the Rocky Mountains in the southwest (Scott 1986). Habitats are grassy areas and lawns. Host plants are grass species from several genera. Eggs are laid on or near the host plant singly. Individuals overwinter as pupae. There is one flight each year in the northern part of their range with the approximate flight time June 15-July 31, and multiple flights all year in southern part of their range (southern Florida) (Scott 1986).
