Adult: forewing varies from light to dark gray; yellowish-to-gold-to-brownish patches on wing vary in extent, either crossing the entire wing or being restricted to the medial area; postmedial (PM) line usually bordered by small pale patch at the costa; hindwing small, dirty white basally, shading to gray distally, with dark veins
subspecies ridenda, which occurs in the west, has gold basal and medial bands on the forewing, interspersed by charcoal gray shading (see photo by Jim Vargo in MPG link in Internet References section below)

In the North, check out Lintner's Gluphisia Moth - Gluphisia lintneri, which may have the PM line lacking or faint and also may have yellow-orange coloring in the ST line.


In the west, check out Gluphisia severa, which usually has a prominent yellow-orange ST line.


In the south-west, check out Gluphisia wrightii, which was formerly considered a subspecies of septentrionis and is a very similar.
