This Caterpillar is pale brown with a darker head and pairs of dark spots along the back. It grows to a length of about 2 cms. It lives in the soil in a silk-lined tunnel. It feeds on :

  • Blue Mat-Rush ( Lomandra glauca, ASPARAGACEAE ), and
  • various Grasses ( POACEAE ).

    It sometimes can become a pest on pastures.

    The adult moth has forewings with brown and silvery white longitudinal stripes. The hind wings are silky and buff coloured. However, when the moth is holding onto a vertical blade of grass with its wings wrapped around its body, the shiny stripes make a good camouflage. The moth has a wing span of about 3 cms.

    The species is found over most of Australia, including

  • Queensland,
  • New South Wales,
  • Australian Capital Territory,
  • Victoria,
  • Tasmania, and
  • Western Australia.
