Podomyrma gratiosa & Crematogaster sp.
South Australia

A large Podomyrma tree ant attacks a column of smaller Crematogaster workers that pass too close to her nest.  The Crematogaster fight back, and even though the large size and heavy armor of the Podomyrma allow it a one-on-one advantage, the superior numbers of Crematogaster give the smaller ants the edge in this fight.
