Natural Habitat
Found primarily in the Southwestern United States and Mexico, living in desert landscapes and urban gardens with host trees like Palo Verde, Citrus, or Mesquite.
Diet & Feeding
Larvae feed on the roots of trees and shrubs; adults generally do not eat or may consume small amounts of nectar or fruit.
Behavior Patterns
They are primarily nocturnal and are highly attracted to bright lights. Females lay eggs in the soil near tree roots where larvae will spend several years maturing.

Harmless to humans although they can deliver a painful pinch if mishandled. They contribute to the ecosystem by breaking down root wood, but large infestations can weaken or kill host trees.
