Click Beetle

Natural Habitat

Found worldwide in varied environments including agricultural fields, forests, and residential gardens; often attracted to artificial lights at night.

Diet & Feeding

Adults primarily feed on nectar, plant juices, and soft-bodied insects. Larvae (wireworms) feed on decaying vegetation, roots, and seeds.

Behavior Patterns

Best known for their unique clicking mechanism used to right themselves or escape predators. When on their back, they snap a thoracic spine into a groove, launching themselves into the air with a clicking sound.

Risks & Benefits

Generally harmless to humans as they do not bite or sting. In the garden, larvae can be minor agricultural pests by feeding on crop roots, but they also contribute to the ecosystem by breaking down organic matter.
