Alternate Common Names:Roadside Skipper, Black Little Skipper.
This species occurs throughout southern Canada and most of the U.S., but can be found only in patches of the southwest. It occurs in northern and central Idaho.
These skippers can be found in woodlands or open areas.
Caterpillar: Caterpillars eat a variety of grasses including bentgrass (Agrostis spp.), wild oats (Avena spp.), bluegrass (Poa spp.), and Bermuda grass (Cynodon dactylon).
Adult: Butterflies obtain nectar from flowers close to the ground, such as verbena (Verbena spp.) and self-heal (Prunella vulgaris).
Caterpillars construct shelters of rolled leaves tied with silk. While in the shelter, the caterpillar produces a white, waxy, outer covering for itself. Once the wax shield is complete, the caterpillar exits and remains outside. Usually there is only one generation of caterpillars each summer, but two may occur in the southern parts of its range. Caterpillars overwinter in a physiological state called diapause. Adults generally fly from March through July. This is the most common skipper of North America.
Males perch and wait for receptive females. Greenish-white eggs are laid singly on host plants.
