This page contains information and pictures about Mottled Predatory Click Beetles that we found in the Brisbane area, Queensland, Australia.

How Click Beetle click?
Click Beetles have the prothorax loosely joined to pterothorax. The clicking mechanism consists of a long prosternal process which can be suddenly be snapped into a cavity in the mesosternum (the underside chest of abdomen) thus causing the prothorax to move quickly relative to the hind body. In so doing produces the click sound and flicks the beetle into the air.
