Erynnis juvenalis

The Juvenal's Duskywing (Erynnis juvenalis) is a butterfly of the Hesperiidae family.

Appearance and distribution [edit]

Underside view

Common in eastern North American oak woods from southern Manitoba to southern Quebec and Nova Scotia southward to Texas and Florida. This dark brown skipper is larger than most eastern Duskywings (wingspan: 30 to 37 mm). It has one brood in the spring (May to late June) in the east but two broods in spring and summer in the southwest. Both sexes have two to four white spots on the forewing. The females have greyer forewings and are more boldly marked. Both sexes have two spots near the upper margins of the ventral side of hindwings that are diagnostic of the species.[1][2] Larval foodplant: Oaks
