White-Browed Shortwing (Brachypterx montana)

Right at the summit of Doi Inthanon, I was disappointed not to spot any dragonflies walking around the nature trail. However, I did spot a male White-Browed Shortwing with distinctive white markings on the head. This is the only specimen I have ever seen. Unfortunately, I didn't really have the camera gear to get very good photos. Many thanks to my brother, Paul Farrell, for the ID.
