armyworm
Marching crop pest
Armyworms are caterpillars that travel in large groups, devouring crops and vegetation as they move.
The name comes from their habit of marching together across fields like an army on campaign.
Several moth species produce armyworms, and outbreaks can devastate lawns, pastures, and grain crops: The armyworms stripped the cornfield overnight.
