Ethoprop is used as an insecticide against soil insects like wireworms and as a nematicide. The larvae, known as mealworms or false wireworms, are usually fossorial, heavily armored and nocturnal. The corn crake may take pests such as "Sitona" weevils, leatherjackets and wireworms. However, some crows also eat many agricultural pests including cutworms, wireworms, grasshoppers, and harmful weeds. Its larvae superficially resemble small wireworms or true mealworms (Tenebrio spp.). Some elateriform larvae of click beetles are known as wireworms.
