The photo above is an old one-- I blogged about it HERE. I took it in the garden a long time back. I'll never duplicate that luck, but I continue to be fascinated by dragonflies and spent some time by the goldfish pool trying to get some close ups.
This one, with the semaphore wings is, I think, a young White Tailed Dragonfly. The tail is all white on an adult.
And this metallic beauty is a Blue Dragonfly. I'm not sure about the one below . . .
I welcome more information on these critters.
