Seedcorn Beetle
(John Obermeyer, Purdue University)
Common Name: Seedcorn Beetle

Order: Coleoptera

Family: Carabidae

Pest Status: Seedcorn beetles can become serious pests of newly emerging corn plants, and especially during cold or wet conditions when emergence is delayed.

Appearance: Adults are small, slender, flattened, brown beetles that sometimes have two darkened stripes on their wing covers.

Life Cycle: Seedcorn beetles overwinter as adults or pupae. The eggs are deposited on seeds, emerging plants and in decaying material. After two days, larvae hatch and develop into adults within the soil. There are approximately three generations per year.

Where to Collect: They are usually in high numbers when cool, wet weather occurs. They are highly attracted to lights.
