Common NameTwo-spotted Looper Moth, Twin Gold Spot SeasonalityAdults have been collected in Alberta in from mid-July through August. IdentificationA medium-size moth (3.7-4.0 cm wingspan). The forewings are dark rust or pink-brown and tan, the central area and a broad subterminal band darker than the rest and the central area in particular largely metallic. Lower portions of the antemedian and postmedian lines are usually marked by metallic silver scales. There is a large, two part (but often joined) bright silver-gold stigma in the center of the forewing, as well as a small silver spot just inside the base of the reniform spot. The inner part of the stigma is shaped like a G, while the outer part is oval, both infilled. Hindwings are sooty brown, shading into a wide dark terminal band. The antennae are simple and the sexes are similar. Overall, similar in appearance to A. metallica, which occurs in the southern mountains of Alberta. Metallica is usually darker brown and has a one part teardrop-shaped stigma.
