Like butterflies and moths, dragonflies and damselflies are kind of similar but also kind of not. Damselflies are usually smaller and not as fast as dragonflies. Dragonflies are among the fastest insects on earth and when they’re not flying their wings are held out and perpendicular to their body, whereas damselflies keep their wings held along and parallel to their body.
And the eyes of most dragonflies touch whereas the damselfly’s are apart. Neither can walk well. They both like to eat flies, mosquitoes, and other small insects and can eat many times their weight in mosquitoes on a good day.
