The black stream glider (Trithemis festiva), also known as the indigo dropwing (as it is part of the dropwing family, this seems appropriate).
OK, lets talk photo stuff for a little bit, as i was trying something new here, which camera buffs maybe interested in.
OK, this is shot with a 50mm lens, and about as close as i can get. Nice for habitat and to set the scene.
Then i put a 26mm extension tube (cheap as chips) on between the lens and the camera body, and i can get much closer (and a cooperative dragonfly helps). At this range i also am using a fill flash to be able to keep my shutter speed high enough to handhold and to fill in shadows.
And then, I can crop the images to get a lovely close up, more abstract shot of its wonderful wings. And look at those funky eyes....
