These caterpillars can be agricultural pests, attacking grain such as:

  • Pearl Millet ( Pennisetum glaucum, POACEAE ).

    The caterpillars are off-white, either greenish or reddish, and have three dark red lines along the body. By day they rest in a web in the soil by a foodplant, emerging to feed on the plant at night.

    The adult moth has light to dark brown forewings, each with a submarginal dark band, and marginal fringes. Each forewing also has a dark spot near the middle. The moth has a wingspan up to 2 cms.

    The species is found over much of the tropics, including:

  • La Réunion,
  • Namibia,

    as well as in Australia:

  • Western Australia,
  • Queensland, and
  • New South Wales.
