Black-tailed skimmer

Someone told me it's Dragonfly Week, so here is a celebration! This beautiful boy is a black-tailed skimmer, seen by my local lake. He didn't seem to mind me watching him and it was fascinating watching his head twitch around as he sighted potential meals. 

Someone else told me that dragonflies are the most successful hunters, based on likelihood to catch their prey. I wish them all success. The most beautiful of insects.
