Natural Habitat

Found primarily in the Southwestern United States and Mexico, inhabiting desert and semi-desert urban areas with trees like Palo Verde, Citrus, and Cottonwood.

Diet & Feeding

Larvae feed on the roots of trees and shrubs; adults usually do not eat and focus on mating, though they may consume nectar or fruit occasionally.

Behavior Patterns

Active during the summer monsoon season; adults are nocturnal and attracted to lights. They are clumsy flyers and stay on the ground during the day. Larvae can live underground for up to 3 years before emerging.

Risks & Benefits

They have powerful mandibles and can deliver a painful bite if handled, but they are not venomous. Benefits include aiding in natural decomposition, though their larvae can weaken or kill stressed trees.
