This species occurs in patches of the western U.S., including eastern Washington, parts of Idaho, and Nevada and Utah, extending into parts of Colorado, Arizona, and New Mexico; also through much of California.
It occurs in open areas including woodlands, chaparral, deserts, and rocky areas along waterways.
Caterpillar: Caterpillars feed on the leaves of members of the mallow family (Malvaceae), such as hollyhock (Althaea spp.) and globemallow (Sphaeralcea spp.).
Adult: Butterflies feed on flower nectar.
Caterpillars live in shelters made of leaves rolled or tied with silk. There are multiple generations of caterpillars every year. The stage that overwinters has not been reported by scientists. Adults fly from April through October.
Males actively patrol in search of receptive females, often in canyon bottoms. Females lay yellow eggs singly on new leaves of host plants. The eggs turn white before hatching.
|Idaho Status:||Unprotected nongame species.|
populations levels are secure, but may be of concern in the future.
