Derobrachus hovorei

Species of beetle

Derobrachus hovorei is a species of beetle in the family Cerambycidae, known variously as the palo verde beetle, palo verde root borer, or palo verde borer beetle. For over 100 years, this species was confused with the related species Derobrachus geminatus, and only recognized and given its own name by Santos-Silva in 2007; essentially all literature prior to 2007 therefore incorrectly uses the name geminatus for this species. It is a longhorn beetle native to the southwestern United States and northern Mexico which derives its common name from the palo verde tree, and it is one of the largest beetles in North America, reaching up to three and a half inches in length. Adults are black or brown in colour, have long antennae, and spines on the thorax. They have wings and can fly, albeit awkwardly at times. Mature beetles emerge in the summer to mate. While not harmful to humans, they can bite in self-defense.
