Several species of wireworms, all quite similar in appearance, attack the roots of many crops. The name wireworm aptly describes these insects (Fig. 1). When young they are cream colored, about 1/4 inch long, and less than 1/16 inch in diameter; when mature they are 1 1/4 to 1 1/2 inches long and about 1/8 inch in diameter. The pupal stage is free, the entire structure of the adult's body being apparent. The adult is a click beetle (Figs. 2,3). When placed on its back, it flips into the air with an audible snap and lands on its feet. The eggs are tiny, white globules found in the soil.
