Thanks RobertD. Was this moth seen on or anywhere near a citrus/ lemon tree, or perhaps on Phebalium (genus), see 'Moths in the ACT', page 56? A new species for NatureMapr's Canberra and Southern Tablelands region when confirmed. Excellent photos.
There is a lemon tree about 12m away and another one about 25m away. I don't believe we have Phebalium on our property (nor any of the immediate neighbours'). Thanks for applying your knowledge to this sighting.
