    The species occurs as various subspecies around the orient, including :

  • Borneo,
  • Nouvelle-CalÚdonie,
  • Philippines,
  • Thailand,

    as well as in Australia in

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

    The range and DNA barcode are sufficiently similar to that of Nyctemera secundiana, to suggest that these are two races of the same species, or else ecological variants of the same species. This cannot be decided until they have been more studied.
