What I noticed was a small "dragonfly" (flying more strongly than most damsels, as well as larger) and the vivid red of the head and thorax., with some kind of color on the wings. Then it perched and I saw that half the wing length was red. Since to photograph it I had to balance on a tiny ridge of gravel just underwater, in the stream, and the light was fading and the wind was blowing...the pictures aren't perfect. But this is a "lifer" for me, and a new species for the place, so the less-than-perfect images don't bother me. Much.
The head and thorax were brilliant metallic red, and the red on the wings was a rich crimson. The abdomen is metallic green with those little whitish "rings", as if it were a green twig. The insect was flicking its wings a little open then snapping them shut (note blur at upper edge as the wind blew the plant it was perched on. The light was open shade, late in the day.
I'm hoping for good light tomorrow or the next day, so I can catch this fellow in sunlight (maybe)--I'll be toting my bigger lens and the monopod. And probably the rubber boots so I can stand in the creek without teetering on loose rocks.
