This species ranges from southern British Columbia south to southern California and Mexico, extending east as far as North Dakota south to New Mexico and Texas. It occurs through most of Idaho.
It can be found in a variety of open areas, including fields, gardens, vacant lots, and other disturbed areas.
Caterpillars feed on the leaves of many species of mallows (Family Malvaceae).
Adult: Butterflies drink flower nectar.
Caterpillars live in silk nests among the leaves of host plants. The number of generations of caterpillars each year varies regionally, with two in the Rockies, one at the highest elevations, and many occurring all year in parts of California and the southwest. Adults generally fly from early spring until fall through most of its range. Butterflies commonly overwinter in a physiological state called diapause, although caterpillars and pupae have been reported to overwinter, as well.
Males perch to wait for receptive females. Eggs are laid singly on the uppersides of leaves of host plants.
|Idaho Status:||Unprotected nongame species.|
G5; populations are widespread, abundant, and secure.
