Mature Rhinocypha chaoi and a female Macromia septima

July 12 I went to Mau Son in Lang Son Province, another long drive. And at Mau Son followed the grueling walk down to the stream in the valley, followed by the climb back up. It was warm and it was not pleasant. I also received several bee stings (thank you, bees).

But I found what I came for, Rhinocypha chaoi. One of the prettiest damsels I have seen (and I have seen many). In May I had an immature male, but really wanted to see the adult. In the end I saw 5 males and a female.

While searching for them I noticed a smallish Macromia that flew a few round over the stream and then went up into a tree, where it hung from a leaf. I could just catch it and I was thrilled to see it was M. urania. But then I noticed the face was reddish, and thus it was M. septima! Only the second time I see this species and the second female. The males must be out there!

Male Rhinocypha chaoi. This species is so beautiful, it is unreal.

In dorsal view the abdomen is particularly striking. When it flies about you see azure specks dance over the water surface.
The female up in a tree having a snack.
Female Macromia septima. Note the amber wing-patches and the antehumeral surrounded by red (see also below) 
Note the reddish lower half of the dorsal side of the thorax and the reddish face
