I try to make every effort to identify unknown insects (using your site and others) before I ask for your help, but honestly I don’t even know where to begin with this one. I was emptying the water out of our dog’s pool, and at the bottom was this insect. It was a good swimmer, staying at the bottom of the pool and blending in really well with the grass and other debris that had blown into the water. There was also an immature one of these, which I was unable to photograph. This is in Memphis, TN. Any ideas? Thanks,
This is an immature Dragonfly, known as a Naiad.
