This poor male had had a close encounter with some kind of predator, which had left it with just one wing and half its body, its abdomen having been entirely removed. It was so helpless that with every puff of wind it was flipped over.
Yet it still had enough life left to crawl and to flap its remaining wing. This seemed to have been enough to tempt another individual to try to mate with it.
I don't know what the predator was or why it didn't finish its meal, given that its prey was in no fit state to escape. There were fair numbers of dragonflies around, but no birds that I saw.
Suffice it to say that this individual was no longer alive when I left.
