Moths of Victoria: Part 7,)
The adult moths of this species are various shades of brown with varied markings often including a submarginal zigzag line, and a nearly straight line across the middle, and a curved line around the base, of each wing.
The undersides have similar markings, with a dark spot near the middle of each hindwing,, and an exagerated indentation in the zigzag line by the spot. The forewings have hooked tips. The wingspan is about 4 cms.
The species occurs over the southern half of Australia, including:
This species may be the same as Idiodes pellophanes (Turner 1947) or Idiodes tenuicorpus L.B. Prout 1916. In the latter case the name Idiodes prionosema Turner 1919, would become the junior synonym, and would be seldom used. More research on the holotype specimens needs to be done to determine if this is the case or not.
