I think it's a Glassy Tiger!

Arriving in Hong Kong, staying with friends who have a lovely garden up in the hills, I found this lovely creature fluttering by among the flowers. I googled to find out what it is and I think it might be the Ceylon Blue Glassy Tiger...
I'm putting this Blip on at 4 am in the morning, our time sense is all over the place travelling through the time zones....going back to sleep now, I suddenly feel tired!
