Mottled Duskywing (Erynnis martialis)
Mottled Duskywing is rarely seen in North Carolina and may be declining. You can look for it near its caterpillar host plant, New Jersey Tea (Ceanothus americanus), though the plant is much more common and widespread than the butterfly and most searches will come up empty.
