Dragonflies eat a lot, and they constantly hunt for food.
The dragonfly catches a gnat. It grabs a mosquito. Very few insects can out-fly the dragonfly. No matter how fast they go, no matter which way they turn, the dragonfly is usually able to follow. Two engineers at the University of Tennessee Space Institute have been studying the way that dragonflies fly.
