North American Ecology (US and Canada)Polygonia satyrus is resident to the western United States and across southern Canada (Scott 1986). Habitats are along streams and valley bottoms. Host plants are herbaceous and shrubs and primarily restricted to a few species in three families, Urticaceae, Moraceae, and Salicaeae. Eggs are laid on the host plant singly, or in stacks of three or four eggs. Individuals overwinter as adults. There are a variable number of flights each year based on latitude, with one flight, mostly late July in the northern part of the range, three flights between Feb. 1- Nov.30 in the furthest southern part of their range (Scott 1986).
