Eastern Eyed Click Beetle

Alaus oculatus

Eastern Eyed Click Beetle

The adult is found on tree trunks, logs, and woodland edges, especially around decaying hardwood where larvae develop. It feeds little compared with the larva and is best known for its hard body, bold false eyespots, and click mechanism. When flipped over or grabbed, it snaps a spine into a groove in its underside, launching itself into the air with an audible click. Its large eyespots can make predators hesitate by mimicking the gaze of a bigger animal.
