Pacuvius Duskywing

More Butterfly Information Skippers Types of Butterflies Butterfly Pictures

Another rather nondescript Erynnis species, the Pacuvius Duskywing (Erynnis pacuvius) flys in the Western United States, in areas with Ceanothus species, the larval food.

Rocky mountain species show a white skirt at the bottom of the hind wings. West Coast species show a brown skirt.

The brown skirted form looks very similar to the Persius Duskywing (Erynnis persius). The picture highlights the grayish marks on the edges of the forewings.
