Click beetles (Coleoptera: Elateridae) are unique insects because of a special trick they can perform. When they find themselves stuck upside-down or alarmed by a potential predator, they can suddenly “snap” their flexible thoracic joints to create a “click” sound and launch themselves through the air. After jumping several inches from their starting point they usually find themselves upright, ready to continue about their day.
These beetles are found in a wide variety of habitats. Approximately 10,000 species have been described worldwide, with nearly 1,000 in North America alone. The adults and larvae of most species feed on a variety of plant material, but generally fall into the category of “mostly harmless” to humans.
