Erynnis martialis
Mottled Duskywing
Erynnis martialis, the mottled duskywing, is a small skipper butterfly in the family Hesperiidae. It occurs across much of the eastern United States and parts of southern Canada. The species is closely associated with oak savanna habitats and has experienced significant population declines due to habitat loss and fragmentation. It is listed as a species of special concern in Connecticut, where it is believed extirpated.
