Asian Pintail Acisoma panorpoides panorpoides—adult female.
This was photographed in my local patch a few days ago. It is often found quite low down among the vegetation. So it is not the easiest dragon to photograph.
By the way, one of my dragon shots emerged the winner as the Best Dragonfly Moments Macro Capture of 2008—in a contest in Flickr. Click here to see all the entries and the voting process and here to see the winning shot of mine announced.
