RECOGNITION
Adult flies, except for wingless species, have two functional wings and two halteres. The halteres are club-like appendages that are essentially the modified hind wings. The only other adult insects that only have two wings in both sexes are the Strepsiptera, which have the front wings reduced rather than the hind wings. Males of some species of Mayflies and scale insects have only front wings. A few tiny parasitic wasps, e.g. Mymarommatidae, have their hind wings reduced, but these can be distinguished from flies as the wasps have only one vein in their front wings and flies always have two or more veins in their wings as long as their wings are membranous.
