A Tandem

That's what this coupling is called, it appears.  It's a pair of Large Red Damselflies, according to my quick research.  I was impressed at the agility and strength of the female, and the coordination of both in their flight as well as their egg-laying.

The female is mostly underwater in this shot, with her head and wings just above the surface.  Her abdomen is bowed, I assume in the process of laying eggs on leaves underwater.

This is my first serious use of my new Fuji 50-230 zoom and I'm pretty impressed.
