Your photo is of a Polyphemus moth. Thanks for the great photo!
This is one of the silkmoths, family Saturnidae, which are the largest of all moths. This is one of the most common.
They overwinter in large silky light brown leaflike cocoons.
The larva become large green caterpillars. They feed on a wide variety of leaves of trees and shrubs including willow, birch, hickory, maple, oak, and members of the rose family like apple.
The adult moths do not eat, but live from the stored food of the caterpillar.
