The spotted cucumber beetle feeds on a wide variety of plants, including cucumber and cantaloupe as well as beans and corn. Adults are yellow-green with12 black spots on their wings.

The larvae feed on the roots of the host plants. Adults can feed on as many as 200 alternate host species and can damage the flowers, stems and new shoots of vegetables and ornamental plants. Females lay eggs in moist sold cracks and two to three generations are produced each season.

Row covers can help with management if put on prior to July, when migrating adults first arrive. Heavy layers of mulch can prevent the females from laying their eggs as they cannot get to the soil. Meticulous cleanup and disposal of debris is critical to removing over wintering adults.
