The genus Messor includes ants that are known for their excellent food storage abilities. These ants are often called harvester ants because of their ability to harvest seeds and store them in their nests. Messor ants are medium-sized and have strong jaws, which helps them manipulate seeds and other food sources. They are active foragers and are known to form larger colonies. This genus of ants provides an interesting subject for study and behavior both in nature and in captivity.
