The Caterpillars of this species are brown with a faint darker line along the back, and a pale line along each side. The head is rounded, but the tail is forked. The Caterpillars feed on grasses ( POACEAE ) including various Australian native species as well as the introduced :

  • Perennial Ryegrass ( Lolium perenne ).

    The upper surfaces of the wings of the adult butterflies are brown with pale yellow patches. The forewings each have a subapical row of small white spots. The upper sides of the hindwings each have two or three eyespots.

    Underneath, the forewings are fawn with black and off-white patches, and a row of three white spots. The underside of each hindwing is brown with dull orange patches, and a subterminal arc of small eyespots. The butterflies have a wing span of about 3 cms.

    This species is found in Australia only in Tasmania, as several races :

  • hobartia in the east and the mountains,
  • montana Couchman & Couchman, 1977, inland in the mountains above 900 metres, and
  • tasmanica (Lyell, 1900) in the west.
