A male and female of the same species on a blackberry, Rubus, flower. Female (dark, shorter, bicolored antennae) is on left, male (brown, longer antennae) is on right. (See caption to other image for reference on gender.) The darker individual (female) was scared up by my approach and flew onto some poison ivy, where I was able to get a closer shot.

Both Brimley (1) and the North Carolina State Entomology Collection family Incurvariidae lists just genus Adela (from subfamily Adelinae in that classification) and just one species, A. caeruleella (syn. bella). Brimley lists A. bella from Raleigh (near Durham) in April and May. So this is likely Adela caeruleella.
