The Dragonfly. As kids, we used to call them as 'Helicopters'. I've heard about kids tying its tail to the end of a string and enjoy watching it struggle to fly - never seen though. I must admit that I would not have liked it if I were a dragonfly.
There was a time when we used to spot dragonflies around puddles, lakes and other similar water bodies. I spotted this one clutching itself to a wire in an institute.
Perhaps, it was the 'thirst' of knowledge that made it land there. #badjoke :)
