Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Munroe (1976)                                                                                 
Adult Markings: In this species, the head, thorax and forewing are shining lead gray, with the head and thorax particularly shiny. The forewing is unmarked and is overlaid with black-tipped, whitish scales that are most concentrated on the basal two-thirds of the wing (Forbes, 1923; Munroe, 1976). The hindwing is also lead gray, but somewhat paler near the base. The fringe of both wings is concolorous with the wings.
Forewing Length: 8-10 mm (Munroe, 1976)
Adult Structural Features: Munroe (1976) has descriptions of the male and female genitalia.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larval life history is undocumented, although Terry Harrison (BugGuide) has reared the adults from a Collinsonia sp.

Habitats and Life History
Habitats: Our specimens are from rich mesic woods in the Blue Ridge.
Larval Host Plants: The only known host is a Collinsonia sp. (BugGuide), which suggests that Collinsonia canadensis could be a host in North Carolina. - View
Observation Methods: The adults are attracted to lights.
