Click beetles are also called elaters, snapping beetles, spring beetles or skipjacks, so called because they are characterized by the unusual click mechanism they possess. They do this by snapping their spine on the prosternum into a corresponding notch on the mesosternum, producing a violent “click” that can bounce the beetle into the air. Clicking is mainly used to avoid predation, although it is also useful when the beetle is on its back and needs to right itself.
