I saw these three dragonflies in the same area on June 10 and was struck by the different perches and poses they use.

A dragonfly perched with the abdomen pointing up is known as being in the obelisk pose or obelisking.

So what is pointing down? Anti-obelisking or just going with gravity?

Commonly they perch parallel to the ground.
