About Dysstroma hersiliata (Guenée, 1857)
Adult Dysstroma hersiliata moths are mostly gray, with black and white patterning across their wings that varies between individuals. The most distinct feature of this species is a solid orange bar that crosses the upper-middle portion of the wing. It has a pale discal spot on the hindwing, and a wingspan measuring 25 to 29 millimeters. It has very short palpi, and shows very limited to no sexual dimorphism. The larvae of Dysstroma hersiliata are lime green, with two off-white stripes near their hind end. This species is distributed across southern Canada and the northern United States, ranging from the Pacific coast to the Atlantic coast. It is more commonly found in the eastern half of this range.
