Several species of wireworms, such as the Pacific coast wireworm, Limonius canus and the sugarbeet wireworm, L. californicus (Coleoptera: Elateridae), are important pests of potato. Larvae are hard and range in size from 8 to 12 mm long. Larvae tunnel or scar maturing tubers making the crop unmarketable. Adults are often referred to as "click" beetles because of their habit of snapping or clicking when placed on their backs. Most wireworm species require 2 to 3 years to complete development.
