The buzzing sound of mosquitoes when foraging tells people: I am here to suck blood. The thing is, it's so difficult to photograph them, which is really annoying. The reason why you hear this sound is related to the characteristics of mosquitoes looking for food. In addition, the high-speed vibration of the wings during flight must make a sound.

Life experience tells us that mosquitoes like to fly around our ears. But in fact, they don’t come for the ears, but for the nose. It’s just that the nose is close to the ears and is easily heard. Mosquitoes need carbon dioxide, odorous organic matter, etc. to feed. Humans breathe through the lungs, and the gas inlet and outlet is the nose. Mosquitoes will fly towards people against this obvious flow of carbon dioxide. Therefore, even if there is a risk of being discovered by humans, they will still come for the mouth, eyes and nose. If you don't enter the tiger's den, you won't get the tiger's cubs. However, they are small in size and fly and turn very quickly, so it is not easy to photograph them.

The wings vibrate. The buzzing sound of a mosquito is caused by the vibration of its wings. Generally, mosquito wings vibrate about 594 times per second when flying; this vibration causes us to hear a "buzzing" sound when the mosquito flies.

When the human body is active, it will sweat, and the sweat will contain some odorous organic substances. Mosquitoes can also rely on these to detect the human body, so sometimes you cannot hear mosquitoes while sleeping, and your arms, However, there were a lot of stings on my legs because the sweat glands were developed in these places. Biting people means eating, and even if there is danger, mosquitoes have to take risks to suck blood. Even if a few are killed, relying on the huge population of mosquitoes, it will not have any impact if hundreds of thousands of people die.

The mosquitoes that bite are all female individuals, and the male individuals can live by sucking the sap of plants and trees. Humans should be lucky that mosquitoes are like this. Otherwise, the bite will be more frightening. It is not as simple as buzzing. Conditions If not, it might really “move” people away.
