Polycanthagyna erythromelas

I am reaching the end of species that I have not published on the blog yet, but there are a few more to go. One is Polycanthagyna erythromelas, an aeshnid that is not rare, seemingly, but I have not seen it often. In fact I had only a few females flying by through the months, for instance at Tay Thien, Tam Dao National Park and once a male hanging in a tree over a small pond in a rocky stream on a hill side in Ba Be National Park in early August. I could take a few distant shots before it dropped of its perch and darted off to new and unknown adventures. This is it:
