    Staff Writer (9/23/2014): The Horse-Bean Longhorn Beetle lays its eggs on a variety of trees commonly found in southern U.S. states and Mexico. Citrus, ficus, willow and hackberry trees are common host plants. Horse beans are also called broad beans, or fava beans, and they grow on a woody shrub or tree. These are also host plants. Larvae hatch and bore into the trees where they remain until they emerge as adults.

    Bright red/fuscia saguaro cactus fruits are a juicy food source for populations living in or near the Sonoran desert. Male Horse-Bean Longhorn Beetles have large jaws extending from the head that are used to battle other beetles trying to partake of a claimed cactus. Females lack these menacing mandibles.
