Wing Span: 7/8 - 1 3/8 inches (2.2 - 3.5 cm).
Life History: Males perch on grass or weeds to look for females. Eggs are laid singly on host plant stems or leaves. Young caterpillars chew holes in the underside of leaves; older ones make channels in the leaf tissue. Chrysalids overwinter.

Adult Food: Nectar from many flowers including common buttercup, white clover, butterflyweed, yarrow, ox-eye daisy, and various composites.
Habitat: In disturbed places in the East including pastures, landfills, vacant lots, road edges, old fields; rocky places in alpine habitats, and tundra in the arctic.
Range: Nova Scotia south to Georgia, Tennessee, and Arkansas; west across Great Lake states to North Dakota. Native populations found in the Arctic and the western mountains. Comments: Eastern and midwest populations probably result from an introduction from Scandinavia during the colonial period.
