The caterpillars of this species are sometimes a pest, attacking various plants in the family SOLANACEAE, including :

  • Tobacco ( Nicotiana tabacum ) ,
  • Bell Papper ( Capsicum annuum ), and
  • Devil'd Trumpets ( Datura species )
  • the fruits of Cape Gooseberries ( Physalis peruviana ).

    The adult moths have a complex subtle brown pattern on the forewings. The hindwings are yellowish orange, with a broad brown margin containing a pale mark. The wingspan is about 2.5 cms.

    The pheromones of this species have been studied. The species can interbreed with Helicoverpa armigera to produce viable offspring.

    Attempts to control the pest include:

  • the use of semiochemicals,
  • a Nucleopolyhedrovirus,
  • the egg parasites wasp Trichogramma chilonis, ( TRICHOGRAMMATIDAE ),

    The species occurs from Africa to the south Pacific, including :

  • China,
  • Hawaii,
  • India,
  • Japan, and
  • Korea,
    as well as in Australia in:
  • Northern Territory,
