As with other Messors they Harvest seeds which are eaten by the ants, using the large Majors jaws to de-shell them they are chewed into a protein rich food source known as "ant-bread". It is this these ants get 90% of their nutrients from. In the wild they build their nests under stones and vegetation. For small ants they build impressive nests up to 4 meters below the surface.
