Colorado Potato Beetle
(John Obermeyer, Purdue University)
Common Name: Colorado Potato Beetle

Order: Coleoptera

Family: Chrysomelidae

Pest Status: The Colorado potato beetle is a serious pest of potatoes, but it can also damage tomato, tobacco, eggplant, and other crops.

Appearance: Adults are approximately 1/2-inch long with rounded outer wings marked with black and yellow-white stripes. The head is tan-orange with black markings.

Life Cycle: The Colorado potato beetle overwinters as an adult in the soil or under litter in gardens or fields. Adults become active in late spring/early summer. The larvae hatch from the eggs within two weeks and take an additional two weeks to reach the pupal stage. Larvae burrow into the ground to pupate and in five to ten days, the adult beetle emerges.

Where to Collect: Larvae and adults can be found feeding on the foliage of host plants.
