Click Beetle (Cryptalaus sp., Elateridae)
All elaterids can click. A spine on the prosternum can be snapped into a corresponding notch on the mesosternum, producing a violent “click” which can bounce the beetle into the air. Clicking is mainly used to avoid a threat or predation, although it is also useful when the beetle is on its back and needs to right itself.
We used to collect and play with small click beetles when we were kids but the thought of a 30mm snapping beetle, spring beetle or “skipjack” probably would have terrified us to death. A beetle this size produces a mighty powerful kick when it clicks.
