All of our current flying technology; airplanes, helicopters, airships; is inspired by bird flight. It uses principles of flight as used by birds.
Principles of insect-flight are completely different from current understanding of flight principles. For example, according to present understanding, an insect should not be able to fly because it can not generate enough “lift”, which is a must for flight.
Now there are many universities studying the insect flights. They have already made prototypes of small air vehicles only a few inches long. These are called MICRO AIR VEHICLES. Example:

Their size is going to reduce further with more research. In future there will be MAVs not bigger than a small bug.
See following animation. It is not much of a science fiction anymore:
By the way, Israel is very much interested in this technology. And we know that whatever Americans develop, Israelis get it the other day.
