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.
This is an example of chemical signaling, which explains why ants all appear to sting at once. Similar to the two-part process of the fire ant bite and sting, the harvester ant will attach to the victim with its mandibles, and so proceed by pivoting around the site, allowing the ant to repeatedly sting and inject venom into the region.
