Have you ever noticed that some Dragonflies point their tails up into the air at times, and wondered why? Well, a number of scientists have given it some thought, and have designed some experiments to answer the question. The research points to dragonflies attempting to cool off. It has been dubbed "The obelisk posture" and has been observed in about 30 species of Dragonflies and Damselflies. A few species lower their tails instead of raising them, but for the same purpose - to keep cool.
