Nicely spotted and identified. The wave pattern on the wing shows it to be a male swiftmoth like your other ones. I'm trying to offer some new data but you know it all. This family HEPIALIDAE also includes ghostmoths like this one http://www.projectnoah.org/spottings/854... http://lepidoptera.butterflyhouse.com.au...

Yes Emma - we have got some very weird and wonderful stuff here and so much is still unknown. It's a bit overwhelming for a total beginner like me.... still, got to start somewhere.

I just found a CSIRO version of martinl's linked species and the tail and orange flecks look better - might go with this id and reference for a while....http://www1.ala.org.au/gallery2/v/Lasiocampidae/Porelavetusta/porela_vetusta_01.jpg.html

Argybee, pinned specimens are designed to display maximum visual information including hind-wings and body that are hidden in photographs. Natural posture, behaviors, foodplants, habitats, dissections and larval stages are also important but need other input, like field observations and photos. For example, if this guy is feeding off the stem, as it seems to be doing, that would be fascinating.

Seems to be sucking on this stem - didn't want to let go even though I handled it fairly roughly to gets angles for shots.

Thanks for that link martin. You're right about there being so many - it's quite overwhelming. Your link looks closer than most I've found so far. It's funny that I found a candidate but soon realised it was better for my previous 'window' spotting. Sometimes I think it's a pity that they 'spread' and pin the specimens making it hard to work out how they would look naturally. The tail is obviously very different. I'll keep that link tagged.
