This could be one of two dragonfly species. They are indistinguishable in a photograph or even in hand, which I do not do. I have decided that it is a Cherry-faced Meadowhawk-Sympetrum internum but cannot be positive.
The other possibility is a Ruby Meadowhawk-Sympetrum rubicundulum. The descriptions for both in my guidebook are identical with one exception. Adult S. rubicundulum is generally found hunting far from water and S. internum is found in wet meadows which is where I made this photograph. The odds therefore are in my favor but I could still be wrong. 🙂
