What is unique about Diptera wings?
These insects are distinctive because their hind wings are reduced to small, club-shaped structures called halteres – only the membranous front wings serve as aerodynamic surfaces. The halteres vibrate during flight and work much like a gyroscope to help the insect maintain balance. All Dipteran larvae are legless.
Are four wings better than two?
It would tend to mean relatively more dedication of mass to wings, so a two-winged bird of the same mass would have more body and probably lower metabolism and less need for food. A major survival advantage of having four wings could be if the bird can fly with one or even two (of the same couple) injured wings.
Why do flying termites lose their wings?
