Female Dythemis velox harassed by male Pachydiplax longipennis

This particular male P. longipennis would not tolerate any other anisopteran within an area about one meter cubed. Anything that perched or flew within the area was investigated.

At one point he succeeded in perching on the end of the female's abdomen while she was obelisking. Her abdomen was promptly weighed down and the curvature plus the intruder's take-off flight made it look comically like a springboard. Unfortunately I did not get that moment.

I sat there for close to 45 minutes observing. Eventually a female descended and landed on this aggressive male's seemingly preferred perch (which was a different branch of this dead limb). Many conspecific males flew by but I was unable to tell if he was the one who mated with her or if it was a different male.
