Pheidologeton affinis marauder ants have one of the largest size disparities between the largest and smallest worker ants in a colony. Here a supermajor uses her massive jaws to cut through tree bark while minor workers stand by. The ants have discovered beetle larvae- a favored prey item- underneath the bark.
