The caterpillars of this species feed on the leaves of aquatic plants in the genus:

  • Water Thyme ( Hydrilla, HYDROCHARITACEAE )

    The adult moths have an intricate brown and white pattern on the wings.

    The species has been found in :

  • Borneo,

    and in Australia in

  • Queensland.

    The species was thought to be the same as the Australian species Ambia eromenalis, and much confusion occurred before the two species were declared to be distinct.
