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.
Pogonomyrmex badius workers transporting a seed to add to their granary Messor sp. carrying seeds into their nest. Harvester ant is a common name for any of the species or genera of ants that collect seeds (called seed predation), or mushrooms as in the case of Euprenolepis procera, which are stored in the nest in communal chambers called granaries.

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.
As of 2019, however, at least one species (Pogonomyrmex occidentalis) is legal to ship within the United States, with the exception of Alaska, California, Florida, and Hawaii. In Europe, some domestic species (such as Formica rufa ) are protected, and it is illegal to own, keep, buy, or sell these ants, or to damage their nests.
Solitary foraging strategies characterize many of the phocids (the true seals) such as the elephant and harbor seals. An example of an exclusive solitary forager is the South American species of the harvester ant, Pogonomyrmex vermiculatus. [19] [20]
