They are impressive creatures, I love their ability to fly and change direction so quickly in flight. It is amazing how many of different art of dragonflies exist. I read in one article that is dragonflies can't fly then they starve because they they only eat prey they catch while flying. Seems like they like of "fresh food". It is a pity that the second one flown away, it would really funny to see them opposite each other like having a chat.
