The front wings are dark gray with wavy crossbands and a large reddish brown spot with a bronze cast near the tip. The back wings are light brown with fringed edges. The caterpillars damage fruits of apple, pear, peach, plum, and other trees. The fruits fall prematurely, and among those picked there is a considerable percentage of rejects.

Caterpillars can be caught in chemically treated paper bands and destroyed. codling moth
