In their larval stage, which can last up to five years in large species, dragonflies are aquatic and eat just about anything--tadpoles, mosquitoes, fish, other insect larvae and even each other.

The smallest living dragonfly is the northern pygmyfly (Nannophya pygmaea) from east Asia, with a body length of 15 mm and a wing span of 20 mm.

Predators that eat dragonflies include fish, ducks, birds, and water beetles.

dragonflies are characterized by large, multifaceted eyes, two pairs of strong, transparent wings, sometimes with colored patches, and an elongated body.

Despite having six legs like any other insect, dragonflies actually cannot walk.
