Hycleus oculatus is a species of insect commonly known as the "eyed click beetle." It is characterized by its elongated body, reaching up to 2 centimeters in length, and its distinctive pair of large, round, black spots on its pronotum, resembling eyes. Found in various habitats, this click beetle is known for its ability to produce a clicking sound by snapping its thorax against its abdomen, which it uses as a defense mechanism to startle predators.
