The native Brown-Shaded Gray sports a variety of colors that bounce and wave their ways across the wings.

Brown-Shaded Grays are part of the Geometer family. The caterpillar is long and slender, posing with half its body off a branch, mimicking a twig. They feed on the leaves of trees like oak, cherry, poplar and willow.

Adults have rows of colors spanning the wings that range from golden brown to steely gray. On the hindwings, a white teardrop-shaped spot almost always touches the black scalloped line crossing the lower half of the wing. A rich, warm brown fills in the area 'under' the black scalloped line. By the head, this same brown sits 'above' the black line. This species closely resembles others in its genus in pattern.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
