Striped yellow, brown, or green worms, from 1/4 to 2 inches long, are feeding on the tip of the ear inside the husk. Leaves may be chewed and ragged.
Insecticides are ineffective once worms are in the ears. For future plantings, apply an insecticide labeled for corn earworm, following directions on the label. Select varieties with long, tight husks, or pinch the silk end of the husk closed with a clothespin.
