Stigmacros worker ants with an Anthrenocerus dermestid beetle larva.  The beetle is likely a commensal inhabitant of the ant's nest, taking advantage of the ants' climate-controlled colony while feeding on debris around the nest.

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.

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.
