The ubiquitous and pale Common Angle Moth may be so widespread thanks to the vast range of its host plant.
Maple trees are the preferred foliage of the Common Angle caterpillar. This means the adult moth can find a good host tree in almost every part of the continent. The small geometer moth has somewhat pointed tips on its pale ivory hindwings. The larger forewings are usually held open and flat, but cross over each other and cover part of the abdomen. Faint brown lines curve around the wings and body. Two dark brown patches that are likened to paw prints sit near the lower part of each wing. A curved indentation on the outer edge of the wings is lined in dark brown.
Caterpillars for the Common Angle Moth are narrow and bright green. Like other geometer caterpillars, they can stiffen their bodies while clinging to a branch making them look like a fresh twig. They feed on all varieties of maple leaves.

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.
