Two Victorian species, P. chlorophragma from the north west, and P pusilla state wide. This moth, the Casuarina Moth was sought without success among the Allocasuarina verticillata in Holey Plains State Park, and other locations, but a larva was found. Click larva to enlarge.
However, the home garden has an Allocasuarina littoralis, and in January 2018 a male came in to the light. This tree occurs naturally less than five kilometres away on a back road, possibly the source of the home population.
