Size
wingspan 33-40 mm
Identification
Adult: forewing varies from medium to dark gray (and shiny under certain light) with orbicular and reniform spots reduced to dark dots; PM line curved, with large convex sinus below reniform spot; ST line straight, composed of dark gray dots or streaks at the veins, and forming sharp boundary between gray forewing and contrasting light gray or pale yellowish terminal area
hindwing light gray, darkening toward outer margin; antennae simple; sexes alike
Range
New Brunswick to Florida, west to Utah, north to British Columbia
Habitat
dry deciduous woods; wooded areas along river valleys; western coniferous forests (?); adults are nocturnal and attracted to light
Season
adults fly from July to September
Food
larvae feed on leaves of Balsam Poplar (Populus balsamifera) and, in the west, Douglas-fir (Pseudotsuga menziesii)
Life Cycle
