REDHARVESTERANT

Red harvester ant

Pogonomyrmex barbatus is a species of red harvester ant from the genus Pogonomyrmex. These large ants prefer arid chaparral habitats and are native to the southwest United States. Nests are made underground in exposed areas. Their diets consist primarily of seeds, and they consequently participate in myrmecochory, an ant-plant interaction through which the ants gain nutrients and the plants benefit through seed dispersal. Ant foraging is guided by chemical signals that lead the ants up to 50–60 km from the nest at times. Red harvester ants are often mistaken for fire ants, but are not related to any fire ant species, native or introduced.
