The Eastern Eyed Click Beetle (Alaus oculatus) is a large, distinctive beetle known for the prominent “eye spots” on its thorax. These markings are believed to deter predators by mimicking the eyes of larger animals. This species belongs to the click beetle family, named for their ability to snap their bodies and flip into the air when threatened.
