Pheidologeton marauder ants have one of the largest size disparities between the largest and smallest worker ants in a colony.  Here a supermajor worker, lined by the much smaller minor workers, uses her massive jaws to cut through tree bark  Beetle grubs, one of many prey items taken by these voracious ants, lie beneath the bark.
