Dragonflies & Damselflies

Ode to Odonata

Dragonflies and damselflies are members of the insect order Odonata. Both have large multifaceted eyes, two pairs of transparent wings and elongated bodies, and both eat mosquitoes and other small insects, such as flies, bees and ants. They're usually found around lakes, ponds, streams and wetlands because their larvae, called “nymphs,” live and develop in the water. Because of this fact, they're considered "aquatic insects."
