What it looks like: 2.0-4.0 cm in length. Its body is reddish-brown, robust, and shiny, with long legs, large mandibles, and long, serrated antennae.

Where you'll find it: They range from Canada through the western United States. They are found all throughout California, but do not commonly appear in desert regions.

Natural History: These long-horned beetles are nocturnal and most active at twilight and before sunrise. The larvae are root feeders and can cause serious damage to oak, madrone, cottonwood and many types of fruit trees including apple, peach, and cherry.
