The Caterpillars of this species have been found feeding on :

  • Wandering Jew ( Commelina cyanea, COMMELINACEAE ).

    oops: slightly missing the starboard rear wing!

    The adult moths have dark brown wings with a diagonal line from near the wingtip to halfway along the rear edge of each forewing. They have a wingspan of about 2 cms.

    Specimens have been taken in

  • Cook Islands,
  • Fiji,
  • Japan,
  • Taiwan,

    as well as in Australia in

  • Queensland,
  • New South Wales,
  • Australian Capital Territory, and
  • Norfolk Island.

    Kollar's 1844 holotype was lost for a period, during which the replacement name Hypena masurialis Guenée, 1854, was suggested. Subsequently the holotype was found and so the replacement name is no longer necessary.

    Hypena obacerralis is superficially very similar to Rhynchina obliquarlis, and they are confused in many collections. We hope we got the above photos correctly identified.
