Giant Robber Fly

Giant Robber Fly (Promachus, 蛮食虫虻属).

Perched on one of the lower reaches of Yuelu Mountain. Comparing with descriptions in my trusty copy of Iconography of Forest Insects in Hunan China (1992), I think it is Promachus albopilosus. It is a real beast of a predatory fly: I have seen several over 3cm in length.
