Hi Nadia - any reason that makes you think it's an Oruza??
The posture and wing shape are very different - wings wrapping around the body, not held out flat.
For my money, this is still Noctuidae, but probably in the subfamily Stictopterinae, genus Lophoptera. I need to check which species as they're mostly similar and several have different colour forms just to confuse the issue more. Another possible genus is Stictoptera, and I would not be surprised to find more species than that which are already known from HK as they're a pretty elusive bunch. Another option is Paectes subapicalis in Euteliinae.
I need to go look this one up!
