“Blue Damsel Fly” by LYLE GLASS.

On a drive through the park, I didn't see any large animals to photograph,,so near a waterhole by the road I saw dragonflies flying around. I stopped to investigate and there were dragonflies and damsel flies everwhere. I photographed both and often returned to the spot.
