Odonata is an order in the class Insecta, encompassing those insects commonly known as dragonflies. These insects characteristically have large rounded heads covered mostly by well-developed, faceted eyes, legs that facilitate catching prey (other insects) in flight, two pairs of long, transparent wings that move independently, and elongated abdomens. Dragonflies are strong fliers with fairly robust bodies and at rest hold their wings either out to the side or out and downward. Damselflies tend to be less robust, even rather weak appearing in flight, and when at rest most species hold their wings folded back over the abdomen. Dragonfly eyes occupy much of the animal's head, touching each other across the face. In damselflies, there is typically a gap between the eyes.
