These rare ants are seldom encountered.  Workers are especially rare while males are more commonly collected, especially in light-traps and Malaise traps. They form colonies of several hundred workers in soil, are predacious on small arthropods including centipedes and forage largely or exclusively in soil.  Workers actively vibrate their antennae.  Some species are known to be nomadic and forage using group-raiding, similar to the army ants.  Some species form new colonies by division of established colonies and the queens never possess wings (they are dichthadiform).  The larvae possess special glands that excrete haemolymph which is then used as a food source by the adults.
