Spotted Cucumber Beetle
(John Obermeyer, Purdue University)
Common Name: Spotted Cucumber Beetle

Order: Coleoptera

Family: Chrysomelidae

Pest Status: Cucumber beetles can be pests of vegetables and agronomic crops.

Appearance: Adults are shiny, greenish-yellow, and have six large, black spots on each wing cover. They are about 1/4-inch long and have black heads.

Life Cycle: Cucumber beetles overwinter as adults in the soil. In the spring and summer the females lay groups of eggs at the bases of plants. These eggs hatch and produce larvae that develop for a month on the roots, pupate in the soil, and appear as adults in early fall.

Where to Collect: They are commonly found feeding on ornamental and vegetable plants.
