A Trachymyrmex worker carrying a dead leaf back to her nest.  These ants are agriculturalists, cultivating an underground fungus that they feed with plant debris gathered from outside.  Trachymyrmex forage mostly on dead plant material, but their larger relatives, the leaf-cutter ants, cut live plant material for their fungus.
