Pupae were collected from twigs in the understorey and kept at around 23 Deg C. Adults emerged about 3 weeks later. The moths are 10 -12 mm long.

They have been identified as Pisara hyalospila in the family Nolidae, subfamily Nolinae (same family as Uraba lugens, the gum-leaf skeletonizer).

Dr. Dave Britton for the Australian Museum in Sydney describes them: 

Adults of this subfamily typically have forewings which are quite triangular in outline, with tufts and/ridges of scales. The head has labial palps that face forwards, giving the moth a “beak”. Males have pectinate antennae. Grey, brown and black are the predominant colours, although some species do have metallic scaling as well.  All of these characters match the adults in the photos. The larvae have the spiny setae, and form a leathery silken cocoon, all of which your species seems to have.

Once we knew what the moths looked like there were times in Late May - early June when they were easy to find resting on the trunks of trees. We noted some on the windows at night.
