Sceliodes cordalis

These Caterpillars are an agricultural pest on various members of the family SOLANACEAE, tunneling into the stems and fruit of:

  • Tomato ( Lycopersicum esculentum ),
  • Cape Gooseberry ( Physalis edulis ),
  • Poroporo ( Solanum aviculare ),
  • Eggfruit ( Solanum melongena ), and
  • Thorn Apple ( Datura ).

    We found one boring into the stems of

  • Butterfly Ginger ( Hedychium coronarium , ZINGIBERACEAE ).

    It was bright pink, and grew to a length of about 2 cms.

    It pupated in the tunnel it had bored in its food plant.

    The adult is off-white, with brown tips to the fore wings, and a pattern of pale brown blotches.
