(n. pl.) An extensive order of insects having only two functional wings and two balancers, as the house fly, mosquito, etc. They have a suctorial proboscis, often including two pairs of sharp organs (mandibles and maxillae) with which they pierce the skin of animals. They undergo a complete metamorphosis, their larvae (called maggots) being usually without feet.
