The moths of this species have reddish-brown forewings, often with wiggly white lines on them. The hindwings are white with brown veins and margins.

In the evening, the male moths are inclined to rest high in bushes, and make high pitched noises by rubbing parts of their abdomen against each other, probably to attract females. The male moths also have a bunch of hairs on the tip of the abdomen which emit pheromones. While resting, the male moths fan their wings so dispersing this scent, presumably also to attract females.

The species is found in across the west Pacific, including:

  • Hong Kong,
  • New Caledonia,
    as well as most of Australia, including:
  • Queensland, and
  • Western Australia.
