Tai Po Kau Headland Conservation Area, Tai Po, Hong Kong
This is a female (fat body and small antennae).
There is a little story to tell about this particular moth. . . .
The species Samia wangi was described and named in 2001 by Ric Peigler and Stefan Naumann as part of their revision of the genus Samia. I had arranged for Prof. Peigler (who visited Hong Kong recently as part of a silk research trip in China) to visit Tai Po Kau with some friends of mine over dinner, and have a moth trap in operation. Fortune was with us, as this beautifully fresh moth turned up at the light - the very first live wild Samia wangi that its describer had ever seen!
