The Ten-lined June Beetle is a large, impressive scarab of western North America with bold white stripes on a chocolate-brown background. Males have spectacularly large, fan-like antennae they use to detect female pheromones at great distances. Adults are attracted strongly to lights and produce an audible hiss when handled. Larvae develop for 3–4 years in soil feeding on conifer roots.
