"Spread Winged Skippers" Juvenal's Duskywing

Juvenal's Duskywing
Erynnis juvenalis



Description 1 1/4-1 3/4" (32-44 mm). FW patterned, HW fairly plain. Above, male blackish-brown on FW with bands of black spots and chevrons and many glossy white spots; HW lighter brown with buff spots somewhat obscured by long, gray hair. Below, similar but lighter. Female much paler overall with more distinct markings. Fringes white or brown. Brown-fringed populations have 2 pale spots near HW tip below.

Similar Species Mournful Duskywing has white spots on HW inside white fringes. Scudder's and Pacuvius duskywings best separated by location.

Life Cycle Egg green, turning pink. Mature caterpillar light green with white specks, thick hair, and red, yellow, or orange head; overwinters. Chrysalis dark green or brown. Host plants are black oak (Quercus velutina), northern red oak (Q. rubra), and white oak (Q. alba).

Flight Usually 1 brood; spring. 2 broods in SE. Arizona; April-September.

Habitat Oak woodlands, scrub oak chaparral, roadsides, and fields near oaks.

Range Manitoba to Nova Scotia, E. United States west to Wyoming, Texas, and SE. Arizona into Mexico.

Discussion Like other duskywings, these sleep with wings folded rooflike over the back, in the manner of a moth. During the day they bask with wings spread.
