Other Common Names:
Purplish-brown Looper, Curved-toothed Geometer Moth
Comments: A genus with just one species, which occurs abundantly throughout eastern North America, including all of North Carolina
Species Status: There is very little variation in nucleotide sequence from North Carolina or elsewhere; no cryptic species are suspected.
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Forbes (1948; as Abbotana clemetaria)Technical Description, Immature Stages: Forbes (1948); Wagner et al. (2001); Wagner (2005)                                                                                 
Adult Markings: One of our largest Geometrid moths. It is variable in pattern but usually dark brown with a conspicuous pale line that runs straight from the inner margin to just below the apex where in makes a sharp inward turn towards the costa. The apex of the wing is falcate and often has a pale patch. The inter-antennal ridge is a contrasting bright white. This species is is unlikely to be confused with anything other than Prochroedes, which is similar in size and pattern and sometimes in color, but has smooth wing margins as opposed to the crenulate margins of Eutrapela. Sexes similar but the female is much larger and far less common at light.
Wingspan: 45-60 mm (Forbes, 1948)
Adult Structural Features: Male antennae are serrate. Reproductive structures of both the male and female are quite distinct from other large Geometrids.
Genitalia and other structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Larvae are twig mimics and easily recognized with practice; the older larvae are quite distinct with their knobby head region and warts over A4 and A8.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Occurs across the state, from the Barrier Islands to the High Mountains.
