See this bug in the Encyclopedia

Natural Habitat

Found in gardens, meadows, and forests; adults often enter homes through windows or doors, attracted to lights.

Diet & Feeding

Adults feed on nectar, pollen, flowers, and occasionally other insects; larvae (wireworms) feed on roots, seeds, and decomposing organic matter.

Behavior Patterns

Known for their unique clicking mechanism: when on their back, they use a thoracic peg to launch themselves into the air with a clicking sound to right themselves or escape predators. Most are nocturnal.

Risks & Benefits

Harmless to humans as they do not bite or sting. In the ecosystem, they aid in decomposition, though their larvae (wireworms) can be significant agricultural pests by damaging crop roots.
