Alternate Common Name: Saltgrass Skipper.
This species ranges from southern British Columbia south through Washington and parts of Idaho to southern and Baja California, extending east as far as Wyoming, Colorado, and New Mexico.
It can be found in a number of habitats, including dunes, marshes, alkali flats, meadows, and sagebrush steppe.
Caterpillar: Caterpillars feed on the leaves of a variety of grasses (Family Poaceae).
Adult: Butterflies drink flower nectar.
The number of generations of caterpillars each year varies with location, from one to two in the north to many in the south. Caterpillars construct nests from leaves tied with silk. Pupae of the last generation of the growing season overwinter in a physiological state called diapause. Adults generally fly from March to November (July to August at high elevations). The butterflies when at rest are found with their forewings partially open and their hindwings fully open.
Males perch to wait for receptive females. Females lay bluish green eggs singly on or near host plants.
|Idaho Status:||Unprotected nongame species.|
