#489 Striped Cucumber Beetle (Acalymma vittatum)

7 July

A beetle of the family Chrysomelidae and a serious pest of cucurbit crops in both larval and adult stages. Large numbers of adults emerge from diapause in the spring to feed on the foliage, flowers, and pollen of cucurbit species. Between one and two generations of beetles can pass in a season depending on the region, with the final generation settling into another period of diapause to wait out the winter.

Females will lay eggs on or in the immediate vicinity of the stem of a viable host plant, often a member of the genus Cucurbita. Eggs are a bright orange color and less than a millimeter in diameter. Eggs hatch after a short period and larvae feed on the roots of the plant.
