General DescriptionA medium-size (approximately 3.3-3.5 cm wingspan) moth with green forewings mottles with black and pale grey and white hindwings. The forewings vary from pale mint green to dark olive green. The orbicular and reniform spots are prominent and green, and the area between the spots and beyond and below the reniform are filled with black. The fringe is strongly checkered black and white. The hind wings are dirty white, usually with a hint of green. They have a prominent wide diffuse darker subterminal band, and a large diffuse discal crescent. Fringe lightly checkered. Sexes similar, but male with bipectinate antennae, female simple. Similar to F. jocosa, which is smaller and usually has less prominent dark blotches on the forewings. The pale hindwings will separate comstocki from both major and jocosa, both of which have dark hindwings. Adults and genitalia of both sexes are illustrated in Poole, 1995.
