Try this to get those elusive dragon flies. I use my 150-600 zoom lens on 600mm and I don't have to get close which also makes them wary. I can stand back and track them instead of up close and trying to get them into the viewfinder to take the shot.
Nice shot. Never seen one like that one

Get some tips from Vas, he is the master BIF and dragonflies in flight. They tend to land on the same perch a few times in a row so if you observe them you can normally tell where they will land. Here's a couple I managed to get. Oh and I think your Dragonfly is a Graphic Flutterer
Great stuff Devster.
