Identification
Field Guide Descriptions: Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948); Rindge (1971); Schweitzer et al. (2011)Technical Description, Immature Stages: Wagner et al. (2003); Schweitzer et al. (2011)                                                                                 
Adult Markings: Along with the other members of this genus, L. pergmagnaria is one of our largest Geometrids, with only Epimecis hortaria being slightly larger. Unlike the other species of Lytrosis, all of which have a strong pattern of parallel lines and black, brown, white, and yellow shades, permagnaria is nearly uniformly gray with only the postmedian line usually conspicuous; the only other mark typically present on the forewings is a dark spot at the costa where the antemedian normally terminates. The hindwings have a similar pattern. The outer margins of both set of wings are strongly scalloped.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The caterpillar is a large stick mimic that feeds until September and then enters diapause to overwinter. It begins feeding the following spring, pupates, and emerges in late May (Wagner et al., 2003; Schweitzer et al., 2011).
Larvae ID Requirements: Identifiable from close inspection of specimens or by DNA analysis.
Distribution in North Carolina
Distribution: Records exist for the Mountains (to 3000') and Piedmont in North Carolina.
