Sleepy Duskywing (Erynnis brizo), (Boisduval & Leconte, 1834) - 3946.000000 - 770087.000000 - Special Concern

Wing span: 3.5-4.5 cm.

Flight time: A single brood, with adults flying from end of April to mid May.

Status: Rare breeding resident.

Distinguishing features: The Sleepy Duskywing shares with the Dreamy Duskywing that the forewings lack clear spots. However, it is larger, and has two continuous and distinct black bands on the forewing above.

Distribution and habitat: This species is scattered and rare throughout the southeastern half of the state. It appears limited to dry oak woods often in close proximity to dry prairie openings.

Natural History: This species is a harbinger of spring that signals the beginning of the season for butterfly enthusiasts. It is most often seen on prairie openings, where its nectars on early spring prairie flowers. Even though adults frequent dry prairie, its larvae almost certainly feed on oak.
