The adult moth has brown forewings with a complex pattern. The hind wings are pale, darkening toward the margin, with dark brown veins. The moth has a wingspan of about 5 cms.

The moth is preyed on by the Bolas Spider ( Ordgarius magnificus, ARANEIDAE ). which emits a pheromone similar to that of the female moth to attract male moths within range of a sticky ball of glue which the spider swings on a length of silk.

The species has been found in

  • New South Wales,
  • Tasmania, and
  • South Australia.
