Common NameDark-spotted Looper Moth SeasonalityAdults are on the wing in Alberta in July and August. IdentificationA medium-size (3.1-3.3 cm wingspan) dull orange-brown moth. The forewings, which are pointed, are crossed by several thin brown oblique and nearly straight lines. There is a faint pinkish iridescence band just outside the postmedian line. The reniform and orbicular are also outlined in a thin brown line, and usually filled with slightly darker scales. The hindwings are darker grey brown, unmarked, and with a pale yellow-brown fringe. The antennae are simple and sexes are similar. In the similar Pseudeva purpurigera, the postmedian line turns abruptly toward the costa near the apex, but in aeroides, the postmedian line runs almost straight to the costa.

Life History Adults are nocturnal and come to light. There is a single brood per year. Conservation A fairly common, widespread species; no concerns. Diet Info No Alberta data; elsewhere a variety of woody and herbaceous plants in the families Asteraceae, Laminacea and Rosaceae. Possibly a general feeder on herbaceous plants. Range
