Bean Beetle
Bean Beetle, or Mexican Bean Beetle, a type of ladybug that is an agricultural pest. Both the adult and the larva, or grub, feed on the leaves, flowers, and pods of green beans, lima beans, and other leguminous plants. The adult beetle is yellowish with eight dark spots on the forewings. The larva is yellow and has soft spines on its oval-shaped body. Bean beetles spend the winter on the undersides of plant leaves. In the spring, the female lays a mass of 10 to 50 eggs on a leaf. Bean beetles are difficult to eradicate. Preventive measures include routine chemical spraying of bean fields.
The bean beetle was introduced into the western United States from Mexico. It has spread over most of the United States and eastern Canada.
The bean beetle is Epilachna varivestis. It belongs to the family Coccinellidae of the order Coleoptera.
