 Driver ants do not perform a nuptial flight, but mate on the ground, and the queens go off to establish new colonies.As with most ants, workers and soldiers are sterile females, and so do not reproduce.Male driver ants, sometimes known as "sausage flies" (a term also applied to males of New World ecitonines) due to their bloated, sausage-like abdomens, are among the largest ant morphs, and were originally believed to be members of a different species.
