The Caterpillars of this species are thought to feed on the roots of various grasses ( POACEAE ), including :

  • Short Wallaby Grass ( Austrodanthonia carphoides ),
  • Double-jointed spear grass ( Austrostipa bigeniculata ), and
  • Chilean Needle Grass ( Nassella neesiana ).

    The adult moths have brown forewings, and yellow hindwings on top. Underneath, the males are brown with white markings, and the females white with brown markings. They have a wingspan of about 3 cms.

    This species is considered to be endangered. Its status is being studied at York Park in Canberra and Mount Piper in Victoria. Attempts are being made to conserve its environment by the University of Melbourne, the CSIRO, the Melbourne Zoo, and the Royal Canberra Golf Club.
