This Twelve-Spotted Skimmer is the only dragonfly I have seen sitting still this year! Of course, I was out of commission for a while so couldn't visit my favorite haunts where I usually see them. I was pleased that it posed for me long enough to get a picture, even if it was a bit farther away than I wanted, so it's a cropped image.
Something that makes the dragonfly even more appealing: "Many people ask, "What do dragonflies eat?" As adults, dragonflies eat other insects and can consume hundreds of mosquitoes in one day! typically eat mosquitoes and other small insects. They are valued as predators, since they help control populations of harmful insects. Dragonflies are usually found around lakes, ponds, streams and wetlands because their larvae, known as "nymphs", are aquatic. Adult dragonflies do not bite or sting humans, though nymphs are capable of delivering a painful but harmless bite." http://dragonflywebsite.com/index.cfm
Anything that consumes hundreds of mosquitoes in one day you just have to like!
