This species ranges from northern British Columbia south and east across southern Canada to Newfoundland and Nova Scotia. In the U.S., it ranges from the Pacific Northwest south to southern California, Arizona, and New Mexico, extending east as far as western Montana, western South Dakota, and central Colorado. It occurs through much of Idaho.
It occurs in wooded canyons and valleys and along streams and forests.
Caterpillars feed on the leaves of stinging nettles (Urtica spp.).
Adult: Butterflies use flower nectar, tree sap, and liquids from mud for food.
There are generally one to two generations of caterpillars each summer, and sometimes three along the Pacific coast. Caterpillars construct shelters by tying the edges of leaves together with silk. Butterflies feed through the fall, then overwinter in a physiological state called diapause. They emerge in the spring to mate and lay eggs, and may be seen as early as February on occasion.
Males perch to wait for receptive females. Females lay pale green eggs, singly or in small stacks or groups, on the undersides of the leaves of host plants.
|Idaho Status:||Unprotected nongame species.|
G5; populations are widespread, abundant, and secure.
