Derobrachus hovorei, commonly known as the Palo Verde beetle, is a large beetle native to the southwestern United States and Mexico. These beetles are notable for their impressive size, reaching up to 3.5 inches in length. They have long antennae, robust bodies, and are typically dark brown or black. The larvae feed on the roots of trees, particularly Palo Verde trees, playing a significant role in nutrient cycling in their desert ecosystem.

Derobrachus hovorei, commonly known as Hovore's Giant Root Borer, is native to North America. Its geographical distribution primarily includes the southwestern United States, particularly in states like Arizona, New Mexico, and Texas. It is also found in northern Mexico.

Derobrachus hovorei typically inhabits arid and semi-arid regions, characterized by hot and dry climates. These areas often have sparse vegetation and are dominated by desert or scrubland ecosystems. The species is usually found at elevations ranging from lowland deserts to mountainous regions up to about 2,000 meters.

This beetle species is primarily associated with the roots of various desert shrubs and trees, such as mesquite and acacia. The larvae feed on the wood and roots of these plants, playing a role in the decomposition process and nutrient cycling within their ecosystem. The adults, which are nocturnal, are commonly attracted to lights during the warmer months.
