This Caterpillar is off-white with a dark brown head. It is a pest on stored foodstuffs, eg:

  • Rice ( Oryza sativa, POACEAE ),
  • Cocoa ( Theobroma cacao, STERCULIACEAE ), and
  • Peanuts ( Arachis hypogaea, FABACEAE ).

    The caterpillar grows to a length of about 2 cms.

    The adult moth is fawn coloured with a faint pattern on the forewings, and with pale plain hindwings. The tips of the forewings are rounded, but those of the hindwings are pointed. The wingspan is about 2 cms.

    The pheromones of this species have been elucidated.

    The pest is international, occurring for example in

  • India,
  • Italy,
  • Sweden, and
  • U.S.A..

    It was unfortunately introduced by accident into Australia, and now also occurs for example in

  • Northern Territory,
  • Queensland, and
  • New South Wales.

    Attempts are being made to control this pest using :

  • insecticides,
  • poisonous plants, and
  • parasites.

    Grain that has been damaged by this Caterpillar can be used perhaps for chicken feed.
