I posted a female of this species in this pose earlier this summer. Here is a male in a similar pose.

HI Allen, Aside from the fact that the subject is a bit long in the tooth, i.e., is pretty beaten up, this is a very cool image. How did you learn about the cooling behavior?

I love the symmetry and the soft background as well as the pose. There is a bit of depth of field fall off....

Hi Arthur, I observe this behavior (called "obelisking") on very hot days. I prefer shooting a dragonfly head on in this pose due to the symmetry of the wings, the dramatic look, and better chance of getting more of it in focus than from other angles. I first learned of the behavior several years ago from an "online" fellow photography friend that is really into odes. Now it is a common behavior I look for on days that are well above 90 degrees.

Thanks for the lesson Allen. We have lots of 90+ degree days down in here FLA :)

Allen you have a fine shot there, not too many species obelisk in the UK - probably doesn't get hot enough here! I like the pose and the composition, I may consider lowering brightness just a tad, I think this might increase apparent detail.

An interesting behavior. As mentioned the symmetry, pose and bg are very pleasing. I also like the nice simple perch and how the d'fly is holding on.

This is an awesome behavior capture. The upside down pose makes it quite powerful with the full spread. I'd like to see a tad more contrast on the head.
