Distribution Australia - eastern, southern, and southwestern regions.
Systematics Includes some of the smallest of the Hepialidae. Fraus is monophyletic with respect to (1) elongate elliptical scales with a short, finely serrated apical margin and (2) patch of hair-scales at the base of the female hindwing (Nielsen & Kristensen, 1989).
Biology Adults fly mostly in the autumn and a few species occur in large numbers. Larvae of Fraus simulans construct vertical silk-lined tunnels in the soil and feed on surface grasses from within silk lined webbing (Grehan, 1989) Reference Nielsen, , E.S. and Kristensen, N.P. 1989.
