The Caterpillars of this species are orange with a black head and tail. The caterpillars have vestigial prolegs. The caterpillars are leaf miners, eating the green flesh of a leaf between the upper and lower sufaces. Often there are several caterpillars mining the same leaf. The mine often runs along the midrib, with an opening each end, through one of which frass is ejected. The caterpillars have been found feeding on:

  • Forest Red Gum (Eucalyptus tereticornus, MYRTACEAE)

    The caterpillars each pupate loosely in their own mine.

    The adult moths have yellow forewings that each have some black marks near the base, a broken black band across the middle, several silver spots and lines, and dark brown fringes. The hindwings are dark grey. The wingspan is about 1 cm.
