This moth has relatives that look remarkably similar. They are all called Grays, are shades of gray, and they are in the same genus. What helps tell this one apart is the sharpness the angle in the lowest black line on each wing. The others moths have lines that are more rounded and less severe. This is perhaps easiest to see in the hindwings. The middle, lighter band of color on each wing has an oval ring. Patches of brown may color the upper and lower bands.
The skinny green caterpillar has a bruise-colored mark in the middle of the ‘back’. The upper part of the body may be reddish-brown, as if it was sunburned. The head is orange-brown and all of the colors darken as the caterpillar matures. This larva feeds on a variety of tree leaves like alder, birch, black cherry, maple, poplar, senna, and willow. Two broods can be produced each year.

Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
