For your entomological enjoyment, I offer two views of a large and lovely dragonfly we found today. We were unfamiliar with this particular species and were delighted to add it to our odonate list.
Cordulegaster obliqua, Arrowhead Spiketail -- this one was quite fresh and hadn't completely dried after emerging from its nymphal skin. It was about 3 inches long.
Here's a close-up view of its head and thorax.
