How Insects Fly

A particular interest attaches to the study of the wings of insects, because, in some respects, they act more after the manner of human inventions for aerial locomotion than do the wings of any other flying creature. Though man has never been successful in equipping himself with wings, and has largely given up the hope of acquiring them, he has succeeded in making machines that will fly; and, whether his craft is lighter than air or heavier than air, its driving mechanism is a set of rotating blades, the nearest counterparts of which in the animal world are the rapidly-whirring wings of certain insects.
