Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: In this species, both the forewing and hindwing have a black ground color that is overlain with a series of white marks. The forewing lacks an antemedial line and has an incomplete white postmedial line that extends from the costa to the middle of the wing. Most specimens have a white subcostal discal dot near the middle of the wing, and a small white spot near the inner margin that is between the discal spot and postmedial line. The fringe is mostly black, but sometimes has a patch of white near the apex and tornus. The hindwing is uniformly black with a white line that extends diagonally from the subtornal region before ending near the middle of the wing. A second and shorter white line extends from just beyond the middle of the costa at an angle that is nearly perpendicular to the first. The fringe is black.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Distribution in North Carolina

Comments: This species is uncommon throughout its range, including in North Carolina where it appears to be restricted to a narrow band in the central Piedmont. More information is needed on its distribution, abundance, natural habitats and food resources before we can accurately assess its conservation status.
