The Maple Spanworm Moth, Notched Wing Moth, Notched-wing Geometer, or Notch-wing Moth (Ennomos magnaria) is a species of moth of the Geometridae family. It is found from coast to coast in southern Canada and the northern United States, south in the east to Florida and Louisiana and in the west to California.[3]
The wingspan is 43–60 mm. Adults resemble an autumn leaf. The wings are deeply and unevenly scalloped. They are bright orange yellow and variably spotted with brown and shaded with reddish-brown toward the outer margin. Adults are on wing from July to early November in one generation per year.[4]
The larvae feed on the leaves of Alnus, Fraxinus, Tilia, Betula, Ulmus, Carya, Acer, Quercus, and Populus species. They are twig mimics with a green, brown or grey body with white spots. Larvae can be found from May to August. The species overwinters as an egg. Pupation takes place in a cocoon amongst the foliage of their host plant.[4]
