Cerambycidae (longhorn beetles or long-horned beetles) is a cosmopolitan family of beetles characterized by their extremely long antennae, which are often as long as or longer than the beetle's body. There are over 20,000 species described. Many longhorns are serious agricultural pests, as their larvae have the unfortunate habit of boring wood. The Asian Longhorn beetle, for instance has been responsible for the preventive destruction of thousands of trees in Northern Illinois and other locations in the United States.
