Alternate Common Name: Bald Duskywing
This species ranges from southern Alberta and Saskatchewan south to Mexico, with an isolated population in southern California. It occurs in isolated patches in Idaho.
It occurs in open areas such as prairies and forest openings and edges.
Caterpillar: Caterpillars feed on the leaves of certain legume species, including lupine (Lupinus spp.), milk vetch (Astragalus spp.), and lotus (Lotus spp.).
Adult: Butterflies drink flower nectar.
Caterpillars live in nests made from leaves rolled or tied together with silk. There are two generations of caterpillars each year in most of the range, and possibly more in the Californian population. The overwintering stage has not been observed or reported. Adults generally fly from March through August.
Males perch to wait for receptive females. Females lay eggs singly under the leaves of host plants.
|Idaho Status:||Unprotected nongame species.|
population levels are secure, but may be of concern in the future
