This Caterpillar is green, with a yellow-edged red line along each side along the spiracles. The caterpillar has a pointed conical head. When resting, the cone is folded down to appear as a continuation of the body, and the face cannot be seen.

    The adult moth is grey-brown with wavy lines. Tasmanian specimens are generally paler than mainland specimens. The wingspan is about 5 cms.

    The eggs are smooth and somewhat conical ovals. They are laid in irregular clusters.

    Evidence from DNA has shown that most specimens from mainland Australia that were thought previously to be Hypobapta percomptaria are actually in a species complex currently named Hypobapta tachyhalotaria, and that Hypobapta percomptaria probably only exists in Tasmania. Thus the renamed specimens can be found in

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