This species has a fairly extensive range, from the southeastern portion of Canada west to southeastern Alberta, south through the eastern half of the U.S. to central Texas. Isolated populations also occur along the Pacific coast, in the Rockies, and in Colorado, New Mexico, and Arizona. In Idaho, it has only been documented in Idaho and Clearwater counties.
It can be found in moist, open areas, such as meadows, open woods, and along swamps and streams.
Caterpillar: Caterpillars feed on the leaves of certain sedges including Carex and Cyperus species.
Adult: Butterflies drink nectar mostly from white, pink, and purple flowers.
Caterpillars live in nests of leaves and silk. Each year, there is only one generation of caterpillars in the northern part of its range, two in the middle and several in the south. Young caterpillars, those from the seasons last brood, overwinter in a physiological state called diapause. Adults generally fly from June to early August. Butterflies rest with their forewings held up while their hindwings lie flat.
Males perch to wait for receptive females. Females lay light green eggs singly on the leaves of host plants. The eggs change to a red color before hatching.
