The labium forms the floor of the dragonfly's mouth, the labrum forms the top, while the hypopharynx is inside the mouth and is used in swallowing. Conceptually, then, the mosquito's proboscis is an adaptation of the mouthparts that occur in other insects. The labium still lies beneath the other mouthparts, but also enfolds them, and it has been extended into a proboscis.

As such, they have a single pair of wings. They typically have long, thin legs and a head featuring a prominent proboscis. Mosquito bodies and wings most often are covered in tiny scales.
