Pogonomyrmex maricopa, the Maricopa harvester ant, is one of the most common species of harvester ant found in the U.S. state of Arizona,[1] but it is also known from California, Colorado, New Mexico, Nevada, Texas and Utah, and the Mexican states of Baja California, Chihuahua, Sinaloa and Sonora.

Partial erosion of the cemented caps adds calcium carbonate to the sand dune soils.

In humans, a Pogonomyrmex sting produces intense pain that can last up to four hours.

This may also encompass alkaloids, terpenes, polysaccharides, biogenic amines, and organic acids.

[citation needed] The Maricopa harvester ant plays a major role in decomposition by dragging dead carcasses of insects underground, thereby enriching soil for plants and crops.
