The moths emerge in Spring in late afternoon, and take flight after dusk. The males fly up and down a straight linear path, and when they observe a female take off after her. Mating takes place on the ground. The eggs are laid while flying over a vegetated area around where the female herself lived.

The species is found in south-eastern Australia, including:

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