Alternate Common Name: Montane Skipper.
This species ranges from southern British Columbia east to Saskatchewan, from the eastern Pacific Northwest east to central Montana and Wyoming; and in western Colorado and patches of California and the southwest. It occurs in portions of central and southern Idaho.
Typically found at higher elevations, it occurs in open areas such as sagebrush steppe, meadows, grasslands, and open woodlands.
Caterpillar: Caterpillars feed on grasses including western needlegrass (Stipa occidentalis) and fescue (Festuca spp.).
Adult: Butterflies drink flower nectar.
Caterpillars live in tubes made of silk at the bases of host plants. There is only one generation of caterpillars each summer. They overwinter in partially buried shelters, in a physiological state called diapause. Adults generally fly from late May to early August.
Males perch to wait for receptive females. Females lay white eggs singly on or near host plants.
|Idaho Status:||Unprotected nongame species.|
populations levels are secure, but may be of concern in the future.
