The Caterpillar of this species is expected to feed on dead leaves, as do others in this genus Eulechria, although different species in this genus seem each to prefer different host plants. The caterpillar probably lives in a tubular silk lined gallery, incorporating debris and frass, in amongst the dead leaves.

The caterpillar probably pupates in a larger and looser chamber at one end of the gallery.

The adult moth has yellow forewings, each with a broad brown marginal band. The hindwings are plain brown. The head is yellow, with a dark brown collar. The meta-thorax is yellow. The wingspan is about 1.5 cms.

The species has been found in south-eastern Australia, including:

  • Queensland,
  • New South Wales,
  • Australian Capital Territory,
  • Victoria, and
  • South Australia.

    The adult moths are superficially similar to those of Chrysonoma paracycla, but differ in the shape of the boundary of the forewing brown marginal band.
