The brood of Pheidole ants are favored prey for many army ants. Pheidole are not without their defenses against army ant raids, however.  Major workers with their powerful jaws are specialized for nest defense, and here a defending major (top right) attacks Neivamyrmex army ants as they attempt to make off with Pheidole larvae.
