Taxonomy
Superfamily: Noctuoidea Family: ErebidaeSubfamily: ErebinaeTribe: CatocaliniP3 Number: 930833 MONA Number: 8847.00
Comments: One of 103 species in this genus that occur in North America (Gall and Hawks, 2010; Kons and Borth, 2015a,b), 67 of which have been recorded in North Carolina. Barnes and MacDunnough (1918) and Forbes (1954) placed this species in Group XV, which also includes C. sordida and andromedae, all associated with heaths.
Identification
Field Guide Descriptions: Covell (1984)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: The forewings are usually pale gray but with the inner margin often shaded with black. In form lemmeri, the thorax -- which is normally gray -- as well as the inner margin of the forewing are almost entirely black (Forbes, 1954; Sargent, 1976). A dark basal dash also exists in both sexes. The antemedian and postmedian lines are also black and fine, but sometimes broken or obsolete. The hindwing is marked with orange and black bands. In gracilis, the postmedian black band is strongly recurved and typically end abruptly before the inner margin. Catocala sordida is very similar, but lacks the black basal dash and is usually not so darkly shaded with black. Melanic specimens of these two species may be very difficult to distinguish but if a distinct basal dash is present, then gracilis is the most likely (Sargent, 1976). The hindwings of the two species are also similar but the postmedian black band continues somewhat diffusely along the inner margin towards the base.
Wingspan: 40-45 mm (Sargent, 1976)
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
