The Caterpillars of this species have been found feeding on dead leaves of:

  • Gum Trees ( Eucalypt species, MYRTACEAE ).

    The caterpillars live in a case made from dead leaves joined with silk, later instars carrying their cases around with them, and in due course, pupating in their final case.

    The adult moths have pale brown forewings that have some variable darker spots, a variable dark area along the hind margin, and a variable dark triangle across the margin. The hindwings are pale brown. The wingspan is about 2 cms.
