North American Ecology (US and Canada)Nymphalis antiopa is a resident of most of North America from northern Canada and Alaska to Venezuela, and is migratory in some parts of its range. It also occurs throughout Eurasia (Scott 1986). Habitats are deciduous woodland and suburbs from the subtropics to the edge of the arctic tundra. Host plants are mostly trees and include species from many families, including Saliceae, Betulaceae, Aceraceae, Ulmaceae, Moraceae, Oleaceae, Rosaceae, Tiliaceae, Polygonaceae, Aparganiacea. Eggs are laid on the host plant in clusters with up to 250 eggs per clutch. Individuals overwinter as adults. There are variable number of flights each year depending on latitude with one in the northern parts of the range and in high mountains, occurring in late July, two flights further south, occurring late June to Aug. 15, and in the furthest southern part of their range there are probably three flights (Scott 1986).
