rootworm
Underground plant feeder
Rootworm refers to the larval stage of various beetles that feed on plant roots, especially corn rootworms—among the most destructive agricultural pests in North America.
The larvae tunnel through root systems, weakening plants and reducing crop yields: Farmers rotate crops to break the rootworm cycle.
Adult rootworms are small beetles that feed on leaves, silk, and pollen.
