These Caterpillars live in a shelter constructed from the leaves of their foodplant webbed together with silk. The caterpillars feed on

  • Grass ( POACEAE ).

    The adult moth has brown forewings, each with many narrow longitudinal stripes, and a black dot near the middle. The hindwings are off-white. The wingspan is about 1.5 cms.

    The species is found in

  • Western Australia,
  • Northern Territory,
  • Queensland,
  • New South Wales, and
  • Victoria.

    Meyrick originally described and named a pair of male and female moths as Chilo paramattellus. When he later obtained a true female of Chilo paramattellus and also a male to match the odd female, he chose to rename that first female and the new male with the new name Chilo leptogrammellus.
