May 1, Labour Day, I was working the streams of Huu Lien looking for Asiagomphus (amongst other things), when my attention was drawn by a large whitish insect with red on the abdomen. It turned out to be a fantastic spreadwing damselfly. I had seen it on photos, but did not immediately know what it was. Checking at home made quickly clear that it was Philosina buchi, a species widespread in Southern China, also in Guangxi and Guangdong, and as in so many other cases, it is not withheld by political borders. Its occurrence in Northern Vietnam is thus not unexpected. Here a photo of this fantastic damsel.
