About

The Corn Earworm Moth is a major North American agricultural pest whose caterpillars famously burrow into the tips of corn ears to feed, but its larvae also attack cotton bolls, tomatoes, and dozens of other crops. Adult moths are tan to olive with a dark kidney-shaped marking on each forewing.
