Wireworm (larvae of Click Beetle)

Natural Habitat

Wireworms are found globally in a variety of habitats, but most commonly in agricultural fields, gardens, grasslands, and forests, particularly in moist soil rich in organic matter. They prefer cooler, damp conditions.

Diet & Feeding

Wireworms are primarily herbivorous, feeding on roots, seeds, and stems of various plants, including agricultural crops like corn, wheat, potatoes, and vegetables. Some species can be predatory, feeding on other soil insects.

Behavior Patterns

Larvae are typically found in dark, moist environments like soil, under bark, or in decaying wood. They are known for their hard exoskeletons and their ability to burrow. They are generally slow-moving. The adult click beetles are nocturnal and are attracted to lights.

Risks & Benefits

Risks: Wireworms are significant agricultural pests, causing considerable damage to crops by feeding on newly planted seeds, germinating seedlings, and the roots and tubers of mature plants, leading to reduced yields or crop failure. Benefits: Adult click beetles can be indicators of ecosystem health. Some species of wireworms can serve as food for higher trophic levels.
