Adult: "Compared to most species of the genus, this is a relatively large (25-30 mm), uniformly brownish-gray species with a violet tinge. The forewings and hindwings are about the same color and the outer portion beyond the postmedian line is darker than the basal and median portions of the wings. The dark spot on the forewing varies in intensity. There is otherwise little variation and the species is well illustrated by Rings et al. (1992) and on the Georgia Lepidoptera website. Specimens on which the ground color is not a virtually exact match for those illustrations are some other species. Forbes (1954) also provides a good key, but occasional specimens of the Zanclognatha protumnusalis complex are difficult. They will be browner and not violet tinged but some may approach the size of Z. martha." - "New York Natural Heritage Program. 2013. Online Conservation Guide for Zanclognatha martha."
