How do dragonflies hunt?

Bearded Dragons hunt in lots of different ways depending on the personality of the lizard and the food available. For example my Bearded Dragon will chase after the larger slower crickets but will stay still and wait for the smaller faster ones. Finally a Bearded Dragon's hunting patterns will also change based on the environment they are in e.g. a Bearded dragon that lives in a more open area with little hiding spaces might be more inclined to chase after prey compared to one who lives in a cluttered environment and will be more reserved and stealthy when hunting.
