army worm

Marching pest larvae

Army worms are caterpillars that travel in large groups, devouring crops and vegetation as they move.

The name comes from their behavior—masses of larvae marching together across fields like an advancing army.

Several moth species produce army worms, and outbreaks can devastate agricultural land: The army worms destroyed half the corn crop overnight.
