My Granny used to tell me that dragonflies are the fairies using their magic to disguise themselves from humans. A story I had heard as a child: Dragonflies turn into Fairies at night, and that during the day you could talk to them and they would remember you and seek you out at night as a Fairy... Not only are they good flyers, dragonflies are intelligent too. Now they won't be winning any maths contests and they're not interested in solving puzzles, but they really do make the best possible use of their tiny brains and huge eyes. For example, their intelligence seeps into their flight. They have areas in their brain to individually control each wing.
It was magical. They have fantastic 3D spatial awareness and can accurately estimate speeds and trajectories of all things around them. They don't just chase after prey, they intercept them in flight!
