Wow, lovely shot. Only wish the horizontal stalk at the bottom were absent. Otherwise a lovely shot.
A bit of info : In dragonflies, the male uses the claspers at the tip of his abdomen to grab the female by the back of the head (often against the will of the female). They then fly "in tandem" for a few minutes, and finally settle and form a position called the "cartwheel" (as in this image). They then mate, and the female lays eggs and dies soon after.
