How Insects Fly
Wing Structures and Manoeuverability
Lepidoptera
The large wings of the Lepidoptera are covered with countless tiny
scales of the same material as the wings themselves. These scales are
coloured or just refract the light to produce the beautiful patterns that we see every summer and
obscure the wings which are as transparent as a housefly's.
Diptera
The Diptera, one of the most recently evolved insect orders, are the Red
Barons of the insect world. The common housefly (photo) has converted its hind wings
into stumps which act as a gyroscopes to stabilize it. This is the reason
why flies are able to dart about as they do, changing direction suddenly, turning right angles, even
flying backwards.
