I seem to be getting the hang of photographing dragonflies. The main secret is luck. I have now attempted enough pictures of these guys, that, by the laws of chance if nothing else, I have gotten lucky a few times.
Other than luck, standing in the hot sun by a pond or a creek for a long time helps too.
This is a swift setwing, Dythemis velox
A female widow skimmer, Libellula luctuosa
This is a male powdered dancer, Argia moesta, resting on the limestone by Onion Creek
This is probably a female powdered dancer, but it could be a female blue-fronted dancer. They are hard to tell apart.
This is most likely a female dusky dancer, Argia translata. Female dancers are hard to identify with certainty.
And here is a western pondhawk, Erythemis simplicicollis.
