Identification
Adult - Forewings of O. pseudotsugata are gray brown to black brown (brown tones may predominate in some specimens), with dark transverse markings that are sometimes indistinct. Look for a distinct white spot near the posterior margin of the forewing and a white or buff (sometimes rusty brown) blotch or chevron marking on the anterior-central area of the forewing. The underside of the forewings and both surfaces of the hindwings are brown, sometimes with gradations of black brown on wing borders. Southern moths tend to be lighter than northern.
