Dragon flies are not my area of expertise: Can anyone identify this beauty?

Kate wrote in to say it’s probably Libella saturata. From other photos I’ve found, that seems a good, accurate identification. Citizens of Arizona have been urged to help identify dragon flies, odonates, in their state, and this site explains how to do it with a camera and a notepad — with a fine picture of a Libella saturata for illustration. And, as a reward to Kate and yourself, you may want to hop over to her blog, The Radula, and see what she’s got to look at.
