Dear friends, I think this is not the after mating ritual. The after mating ritual with the female that eats the male is typical of the Mantis religiosa and not of dragonflies and damselflies. It is rather a rare form of cannibalism inside the same specie, it is an unusual event between dragonflies, but that ends in this way after the clash between males. I was present during one of these clashes and I saw the epilogue documented by my photo. I went into a pond with the intention of photographing frogs, but I was intrigued by these dragonflies (Anax Parthenope), which often clashed in the air. During one of these fights I saw something fall to the ground and one of the contenders dragonflies fly away with something between their paws. I followed until it rested on an herb of the pond and I realized that he had the headless body of another Anax Parthenope, body that then he started to eat as documented by the photo. I then realized that what I saw before was the victim's head chopped off during the fight. I returned again several times to this pond, I witnessed these fights in the air again, but without going to this tragic end.
