Have you ever seen the world's largest ant before? It is the Male driver ant or some times called as "sausage flies" due to their sausage like abdomens. These are the largest known ants in the world. Males leave the colony soon after hatching. These largest ants are primarily found in central and east Africa and some times in tropical Asia. The members of this ant family form temporary ant hills lasting few days to 3 months. Each colony can contain 20 million ants. The length of these giant ants is 50 mm or 5 cm.
