General Description
fourni par University of Alberta Museums
A medium-size (wingspan approx. 3 cm) broad-winged dull light and darker yellow-brown moth with a glossy sheen. The forewings are pale yellow-brown, overlaid with dull sooty brown on the basal third and in a broad band across the post-media area. The outer edge of the postmedian band is well-defined and erratic, followed by a thin broken terminal line. The hindwings are similarly marked, but less well defined. The wing fringes are light brown. The entire pattern is poorly defined and "cloudy". Idia lubricalis (Gey.) (see below) is a smaller, darker moth. Some specimens of occidentalis have more dark scaling and a more complete pattern than is evident on the illustrated specimen. Idia immaculalis is pale tan without any pattern. Two other species with a similar color and sheen include Protoperigea posticata (Harv.) and Pronoctua peabodyae.
