Palo Verde Root Borer

Found primarily in the Southwestern United States and Mexico, inhabiting desert and semi-arid urban landscapes where their host trees (palo verde, mesquite, and citrus) are located.

Larvae feed on tree roots (specifically Palo Verde and other desert trees). Adults are typically non-feeding or only consume small amounts of nectar or sap.

They spend most of their life underground as larvae (3 years). Adults emerge during the summer monsoon season for about a month to mate and lay eggs. They are most active at dusk and are attracted to bright lights.

They are harmless to humans but may deliver a painful pinch if handled. They are considered minor pests because larvae can damage or kill stressed trees, but they also serve as a food source for large birds and desert mammals.
