North American Ecology (US and Canada)
Phyciodes campestris is native to western North America from Alaska through California, and as far east as Texas (Scott 1986). Habitats are plains to mountains and Taiga. Host plants are herbaceous, and restricted to one family, Compositae. Eggs are laid on the host plant in large clusters. Individuals overwinter as half-grown larvae. There is one flight each year late June ? early Aug in the far north and in high mountains and 3-4 flights each year in the more southern part of their range (April1-Oct. 31 in lowland Calif.; May1-Sept30 in Colorado plains (Scott 1986).
