Tortricidae, Olethreutinae - genus & sp. indet.
One of around 50 species of this subfamily that await a formal i.d. in Hong Kong.
For moth species that are steeply tectiform (tentlike) in their resting posture, it is better to try and take several different views - from above (like this shot), from the side and from about 45° (dorso-lateral) so as to show all the wing pattern clearly. If you get only one shot, the dorso-lateral view is the best.
