Pests in Gardens and Landscapes

Seasonal development and life cycle—Cucumber beetles

Beetles overwinter as adults in weedy areas and move into planted fields and gardens as soon as plants start to come up. They lay their yellow orange eggs at the base of plants or in soil cracks. Hatching larvae burrow into the ground seeking out roots, feed for 2 to 6 weeks, pupate, and emerge as adult beetles that attack the aboveground portions of the plant. There are several generations a year.
