|Rough Harvester Ant (Pogonomyrmex rogusus)|
DESCRIPTION: L=0.5" (13mm). Overall reddish brown to black in color. Workers have squarish heads.
NATURAL HISTORY: Feed mostly on seeds that they bring back to their large nests. As in most ants, harvester ants are social with a queen that lays eggs and female workers that forage and tend the eggs, larvae, queen, and nest. Occasionally, reproductive males and females are produced (most commonly after a summer rain), and they fly out of the nest to mate, after which the males die and the females form new colonies of their own. The queens mate once, often with more than one male, and then store the sperm the rest of their life (10-20 years). Warning: harvester ants have a powerful sting as well as a bite.
