Pogonomyrmex barbatus is a species of harvester ant from the genus Pogonomyrmex. Its common names include red ant and red harvester ant. [1] These large (5– to 7-mm) ants prefer arid chaparral habitats and are native to the Southwestern United States. [2] Nests are made underground (up to 2.5 m deep) in exposed areas.
Pogonomyrmex (sensu stricto) workers have the most toxic venom documented in any insects, with Pogonomyrmex maricopa being the most toxic tested thus far. [4] It has an LD 50 of only 0.12 mg/kg, compared to western honey bee venom, at 2.8 mg/kg, and comparable to cobra venom.
Pogonomyrmex occidentalis, or the western harvester ant, is a species of ant that inhabits the deserts and arid grasslands of the American West at or below 6,300 feet (1,900 m). [2] Like other harvester ants in the genus Pogonomyrmex , it is so called because of its habit of collecting edible seeds and other food items.

Unusual amongst harvester ants, Pogonomyrmex badius is known for its seasonal nest relocations with colonies on average relocating once per year at a distance of 4 - 10 meters along an established foraging trail. New nests are rapidly excavated within a few days with there being little variance in architectural design between the new and old nests.
