Facts about Cucumber Beetles:

Cucumber beetles are found throughout the United States and southern parts of Canada.

The adult cucumber beetle overwinters under vegetation debris or thick grasses. In areas where winters are quite cold, the cucumber beetle migrates southward to warmer regions. They return to their northern habitats during the spring of each year.

They search for food in nearby fields, eating wood pollen and stems while waiting for the emergence of their favorite crops such as cucumber, bean, and various squash and melon seedlings.

The spotted cucumber beetle will also feast on corn, peas, potatoes, tomatoes, and peanuts among other vegetation.
