Mosquitos are a small creature on Earth, which is near about 5.5mm long. They are able to fly at a speed 1 to 1.5 miles per hour.They have been known to travel up to 75 to 100 miles.
Male mosquitos flat their long wings more than 600 times per second, as per The Physics Fact book. That is four times faster than other insects of the same size. They do a lot of levitating, which also takes techniques that can help to fly slowly.
The insects essentially recycle the energy from the wake of a preceding wing stroke and then tightly rotate their wings to remain in flight, Science News reported. Most of the birds and insects rely on long wing strokes that can create a tiny low pressure, which is so called leading-edge vortices. But mosquitoes rapidly flap their wings up and down around a roughly 40-degree angle on average.
Now, the insects flap their wings in a tight figure eight formation. Leading edge vertices generate a lift as the wings briefly cut through the air horizontally. When the wings start to rotate into curve eight formations, then they trap the wake of the previous stroke. Finally, along with the back edge of wings, mosquitos create another series of low pressure.
The mosquitos shifts their wings turning axis from the front to the back of the wing. It creates a more horizontal surface that allows the wings to continue to push air down. A Cornell University physicist, Itai Cohen, said that switching the axis mid-rotation is impressive, especially since mosquito nerve cells fire just once for every few wingbeats.
Somehow, a mosquito has evolved a complex wing stroke. It takes advantage of aerodynamic forces and the mechanical infrastructure of the wing to generate complex motions with very few signals from the brain. Apart from this, Mosquito wingbeats make high-pitched tones, and males and females harmonize these tones in their search for a mate. A flight style that needs fast flapping and it may have evolved as a result of sexual pressure to reach higher frequencies.
