Pheidologeton affinis, supermajor and minor workers attacking a beetle grub. Supermajors have powerful mandibles useful for cutting up and carrying large prey items.  The supermajor pictured here was able to single-handedly drag this very large beetle larva across the substrate while I photographed them.

Assassin bugs are sit-and-wait predators. This Zelus tetracanthus arrived at a blacklight insect trap and intercepted incoming prey, in this case a male trap-jaw ant.

Worker polymorphism in the marauder ant Pheidologeton affinis.  Pictured here is a single supermajor worker, two major workers, and full complement of minor workers.  These insects are all sisters and are essentially genetically identical, their different morphologies a result of developmental plasticity.
