Palo Verde Root Borer

Natural Habitat

Arid desert regions of the southwestern United States and Mexico, typically near Palo Verde, mesquite, or citrus trees.

Diet & Feeding

Adults may feed on nectar or not eat at all during their short lifespan; larvae feed on the roots of trees and shrubs.

Behavior Patterns

Adults are active during the summer monsoon season, often attracted to lights at night. They have a long larval stage (3-4 years) living underground before emerging to mate.

Risks & Benefits

They are harmless to humans but can deliver a painful pinch with their mandibles if handled. While they assist in decomposition, heavy larval infestations can stress or kill host trees.
