@WendyEM : As it may be unique, I have put a copy of the photo in a webpage of its own: http://lepidoptera.butterflyhouse.com.au/psyc/lepidoscia-D.html I hope you approve? On what plant is it feeding? Are you rearing it? Cheers, Don
looking back through older photos I think this is a spent case (in same spot for months/year..... see also moss/lichen/algae on case) I did spot another recently, will check it for movement. They are on dead twigs of Melaleuca armillaris which seems to be a favoured larval plant of many Lep sp here. Or Maybe they are easy to find on it.
