According to scientists, mosquitoes are so light that raindrops don’t strike them. Instead, they wrap themselves up and fall with them. At the same time, the mosquitoes are covered with waterproof fine hairs, so they can easily escape from raindrops.
Generally speaking, the weight of an adult mosquito is about 0.002 grams, and the weight of an ordinary drop of rain is 0.1 grams, rain after falling to a state of 10 meters/second uniform speed, at this speed was 50 times their weight of rain continuous hit can still be safe, how do mosquitoes have this “super ability”?
About mosquitoes to avoid rain, scientists have specially carried out research, put a mosquito in a fixed transparent container, in the container to simulate the process of raindrops falling, through the high-speed camera frame by frame recorded the whole process, the original mosquito can not quickly avoid rain.
When rain hits a mosquito’s wing, the mosquito sinks in the direction it was hit and spins around, shaking off the rain that hit it and flying on like a fighter jet. Because of their strong exoskeleton and lightweight body, when rain hits the mosquito’s body, the water wraps around it and the mosquito continues to fall under the force of gravity. At this point, the mosquito immediately adjusts its balance and quickly accelerates out of the rain with a horizontal acceleration.
In both cases, when mosquitoes fly, they survive because of their light body and flexible movements. Although the weight of rain is many times that of mosquitoes, when the rain hits them, the mosquitoes also descend, reducing the impact.
But if the mosquito lies on the ground and it suddenly rains heavily, it will be in trouble. Rain from 10 meters per second speed impact on the ground of the mosquito, the speed of rain instant will become 0, this time is very short, mosquitoes will bear the equivalent of their weight 10,000 times the impact force, mosquito weight is 0.002 grams, then the impact force will have 20 grams, for mosquitoes is already lethal. A mosquito flying in the air and being hit by rain on its belly are, for example, as different as a person jumping five metres onto a bed of springs and onto concrete.
In addition, the mosquito can get rid of the rain, the most important thing is that the mosquito’s wings and body are hydrophobic. If the mosquito’s wings are hydrophilic, it will be difficult for the mosquito to escape from the rain, and the rain will stick to its body and fall to the ground. The wings of most birds are hydrophobic, which prevents rain from adding weight and causing flight problems. Ducks’ wings are also hydrophobic, so they don’t get caught in the water when they float on the surface of the lake. Nature has given animals plenty of genes to adapt to the environment, not least mosquitoes. If you look hard enough, you’ll find that many animals’ bodies are more sophisticated in structure and function than any human-made device.
