Western Corn Rootworm (Diabrotica virgifera) on a soybean. Farmers have traditionally fought this insect by rotating corn out with soybeans every year. The insect lays its eggs in the soil, and in rotated fields the emerging young rootworms find themselves lost in a sea of inedible plants. Yet some populations adapted, flying to soy fields to lay eggs so their offspring catch next year's corn.
