A medium size Lithophane (wingspan 3.5-3.9 cm). Forewings light ochre marked with a dull brown median shade and subterminal line. A dark grey bar-shaped patch, somewhat diffuse, in the lower median area. Suberminal line with a slight reddish shade before and a dark shade beyond. Hindwings dark grey, including most of the costal area, and with a dark discal spot and pale fringe. Abdomen tufted. Sexes alike. This is one of the commonest Lithophane at both light traps and bait. Like most Lithophane it is much more commonly collected in spring than in fall. Spring specimens are lighter in color (faded) than are freshly emerged fall specimens. The similar L. bethunei has been recorded west to central Saskatchewan and should be watched for in east central Alberta. It is a paler cream and tan, and can be separated by the cream hindwing with little gray scaling (grey in innominata).

A wide variety of deciduous and coniferous trees and shrubs, with perhaps a preference for cherry (Prunus sp.), alder (Alnus) and poplars (Populus); also other insects (Prentice, 1962; Covell, 1982; Rings et al, 1992)
