Juvenal's Duskywing (Erynnis juvenalis)

This species can be difficult to separate from Horace's Duskywing. The latter begins flying later in the Spring and continues flying into the Summer, whereas Juvenal's Duskywings are done flying by the beginning of June (in NC). Juvenal's Duskywings have more grayish "overscaling" on the dorsal wing surfaces (Horace's lack this), and Juvenal's usually show two whitish spots, which Horace's lacks, below the leading edge of the underhindwing near the apex . Also, Juvenal's females generally are less boldly patterned than Horace's.
