Alternate Common Name: Jagged-Border Skipper.
This species ranges from central British Columbia south to southern California, and east to Montana south to northern New Mexico. In Idaho, it is found throughout most of the state.
It occurs in open areas such as sagebrush steppe, chaparral, grasslands, and open woodlands.
Caterpillar: Caterpillars feed on the leaves of several grasses, including slender hairgrass (Deschampsia elongata), needlegrass (Stipa spp.), and bluegrass (Poa spp.).
Adult: Butterflies drink flower nectar.
Caterpillars live in nests made from leaves tied with silk. There are two generations of caterpillars each summer, the second of which some experts report overwinters in a physiological state called diapause. However, other experts point to the fact that adults can be observed in flight as early as April, suggesting the pupae overwinter as well. Adults generally fly from late April through June and from August to early October.
Males perch to wait for receptive females. Females lay pinkish eggs singly on or near host plants. The eggs turn white or gray before hatching.
