Did You Know…
One of two late summer skippers, this is possibly our most widespread and variable species of this genus, Hesperia, which all show a distinct band of white spots on the hindwing below. To await receptive females, males perch near the host plant or on tops of hills. Females scatter eggs on or near the host plant. Caterpillars eat leaves and live in nests of tied leaves. In the arctic, chrysalis or older caterpillar overwinters; elsewhere egg overwinters.
