The mango hawkmoth - - Amplypterus panopus
(Thanks to Ryan for the lighting on this one below)
hmmm, I do not know too much about this glorious moth.
This one I found walking around Kadoorie Farm. They are very sluggish during the day, which makes close up macro photography easier. But they are strong flyers at night, so I have been told.
Here it is on the fern, and with a hand for size.
many thanks - as always - to Roger Kendrick for this ID and his inexhaustible supply of information and knowledge about moths.
And this is another fruity hawkmoth, the Yam hawkmoth that I found in Thailand...
