The Caterpillars of this species feed on the foliage of :

  • Koda ( Ehretia acuminata, BORAGINACEAE ).

    The caterpillars are hairless, and live in a silk web constructed under a leaf.

    Pupation occurs in a crevice on the trunk or a branch of the host plant. The pupa has grooves lined with yellow hairs.

    The adult moths have white forewings, with a pattern of black dots. The hindwings are grey, fading to white at the base. The abdomen is yellow with black bands, and has a tuft of yellow hairs at the tip. The male moths are unusual in also having a tuft of hair on each antenna. The wingspan of the moths is about 2.5 cms.

    The eggs are flat and scale-like. They are laid singly on foodplant leaves.

    The species may be found over most of eastern Australia, including:

  • Queensland, and
  • New South Wales.
