Adult yellow-collared scape moths have black forewings. The hindwings (usually covered by the forewings) are translucent in the middle; sometimes the patch looks whitish or bluish. The body is all black, or bluish-black, except for the bright orange (sometimes yellow) “collar.”
Larvae have numerous tubercles bearing hair tufts. The body is brownish with a dark line down the back, a broken orange and yellow line to either side of it and a broader line below that. The head is orange with brownish shading.
