Epopostruma frosti - trap-jaw ant
South Australia

photograph © Alex Wild 2005

The boxy mid-section and wing scars of this trap-jaw ant indicates that this is a queen ant.  Queens of most ant species are winged for the first part of their adult lives.  The thoracic structure is enlarged to house flight muscles.  Compare this ant to a worker of the same species.
