The adult moths of this species are chocolate brown with a series of pale lines along the forewings which give the impression that the wings are pleated. The males have a dark spot near the middle of each forewing, and a wingspan of about 4 cms. The females have no dark spot, and have a wingspan of about 6 cms.

This species appears to occur in

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

    The DNA evidence indicates that specimens currently called Pararguda crenulata fall into at least four distinct clusters. So it is likely that four or more different species have been clumped in various collections.

  • One has the forewing black spot and is recorded from northern Queensland.
  • Another has males with the dark spot and ranges from south of Rockhampton to north of Sydney.
  • The third has no dark spot, and has been found from Dubbo to Tasmania.
  • The Western Australian specimens are probably yet another species.
