Dragonflies are some of the most mobile insects on the planet. They can control the angle and speed of each of their four wings independently to fly in any direction, hover and perform acrobatic manoeuvres. Unlike most other flying insects, dragonflies beat their wings up and down instead of the more usual back-and-forth motion.

Dragonfly wings are quite a marvel of science, and their wings are being studied for scientific and technological reasons. Their wings have the natural ability to help them to float, glide, and hover effortlessly. The wings have a lot of stability and have a very high load-bearing capacity, the amount of load an insect can handle before it.
