Pogonomyrmex desertorum, also known as the desert harvester ant, is a bold and powerful species native to the deserts of the southwestern United States and northern Mexico. These ants are instantly recognizable by their deep red coloration, high-speed foraging, and a sting that is both defensive and potent. As true harvester ants, they are granivorous, gathering seeds as their main food source. Due to their aggressive behavior and painful sting, this species is best suited for advanced antkeepers.
Pogonomyrmex milticida
In nature, P. desertorum thrives in hot, arid environments, often clearing large circular zones around their nest entrances, known as “ant plazas.” Their nests are deep and complex, helping regulate moisture in extreme conditions.
