Natural Habitat

Outdoors in gardens, fields, and forests; often attracted to lights and found entering homes through small gaps.

Diet & Feeding

Larvae (wireworms) feed on plant roots and seeds; adults typically feed on plant juices, pollen, or nectar.

Behavior Patterns

Characterized by a unique 'clicking' mechanism where they snap a spine on their thorax to flip themselves into the air if turned upside down or to escape predators.

Risks & Benefits

They are harmless to humans and do not bite or sting. While they can be a minor nuisance indoors, they do not cause structural damage; some larvae species are agricultural pests.
