Here is a link to Arizona species identification, but a look at every
one of them did not give an ID:
Arizona Species Database of International Odonata Research Society/
From all the searching, I believe it is a Darner. I just got an ID a
few minutes ago as: White-belted Ringtail (Erpetogomphus compositus)
The closest similar dragonfly I found has an image here:
I'm waiting for reply from a dragonfly expert and hope to post with the ID soon.
Sent this photo to ID Please on flickr with hopes some of the members able to help. This guy is about 3 1/4" from head to tail. Let me tell you I held still for the stillest an ADD person can get for this unexpected shot. I'd been photographing the neat tall grasses found on the streetcorner at 40th Street off Camelback, going towards the Phoenix Mountains. The set, with all 5 images is here.
I've had 3 ID's now as "white-belted ringtail" so that is now the ID and the mystery is solved. Thank you everyone for your help and interest!
