Dreamy Duskywing
Erynnis icelus (Scudder & Burgess, 1870)
Family: Hesperiidae
Subfamily: Pyrginae
Identification: Long labial palpi point forward; antennal clubs are pointed. Wings are black; forewing has no transparent spots but is dusted with gray scales and has bands of dark spots.

Conservation: Not usually required.
NCGR: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.
