Erynnis brizo, the sleepy duskywing or banded oak duskywing, is a species of Hesperiidae butterfly that occurs throughout North America and is commonly confused with E. juvenalis and E. lucilius.[3] The species is listed as threatened in Connecticut and Maine.[4]

Description[]

The upper forewing is blackish brown with continuous bluish-brown spots. The hindwing is almost completely brown with lighter brown spots. The caterpillar of this species is small and gray green with purplish tips. There is a faint lateral white stripe. Unlike most caterpillars Hesperiidae have distinct heads and the E. brizo's head is brown with an orange spot.[5]

Habitat[]

This small Erynnis stays in oak-pine barrens and cut-over forest. It can be seen near forest edges including near roads, train tracks and towns.

Food plants[]

The larvae consume Scrub oak (Quercus ilicifolia) and other shrubby oaks. The adults consume Nectar from flowers of heaths (Ericaceae) including wild azalea and blueberry; also blackberry and dandelion.[6]
