Why do mosquitoes come and fly on their heads? Why do mosquitoes keep flying over people s heads?

Female mosquitoes are sensitive to carbon dioxide and can tell from the amount of carbon dioxide emitted by an object that it is the target of its blood. The concentration of carbon dioxide near the human head is high, so it attracts mosquitoes.

That's why mosquitoes can fly quickly and accurately from a long distance to people at home. In fact, mosquitoes on top of your head will bite you, but you don't find a good opportunity.

And if the mosquito flies in marriage, that is, in the mating of males and females, it will also fly on the head, but it will never bite.

Mosquitoes hover over a person's head because:

1. People who emit a lot of carbon dioxide.

After engaging in sports or physical labor, the breathing will be accelerated, so that the exhaled carbon dioxide is relatively more, and the carbon dioxide gas will form a moist and warm air flow about 1 meter or so on the head, and the mosquito is more sensitive to this, and the "image" presented by the finch fiber in the mosquito's field of vision is clearer, which is convenient for mosquitoes to conduct directional tracking. People with large lung capacity, fat people, and people who breathe heavily are more likely to attract mosquitoes.

2. People with developed sweat glands.

For those who like to sweat, the acidity in the blood is enhanced, which makes it attractive to mosquitoes. In addition, mosquitoes have a heat receptor in their antennae, which is very sensitive to temperature, and can be immediately detected by the slightest change in temperature. Sweating people's bodies dissipate heat quickly, which will also attract mosquitoes, and the sweat discharged by the human body volatilizes in the air, which can also send a "signal" to mosquitoes.

3. It is a person who likes to wear dark clothes.

The main reason why mosquitoes are nocturnal is because they have a darker habit, and if they wear dark clothing, they will show a dark shadow at night, and the mosquitoes will chase towards darker places. Clothing colors such as black are the first choice for mosquitoes to attack, followed by blue, red, green, etc., mosquitoes do not like to bite white. Similarly, mosquitoes love to bite people with darker skin or reddish skin.

1. A group of mosquitoes will fly overhead Reason: mosquitoes are mating, and the success rate of mating in crowds is relatively high; Mosquitoes can make a carbon dioxide when they get together.

2. The reason why mosquitoes fly in swarms: mosquitoes fly in groups, mainly male mosquitoes, female mosquitoes account for a minority, they are mating in the air, ready to reproduce offspring. The mating of mosquitoes is mainly carried out in the flying.

The mosquitoes on the top of the head are not doing anything else, they are mating. This mosquito is called the midnight.

The task of every midgester after birth is to complete mating, and they do not suck human blood, but only eat sweet things.

3. The formation of flying is related to light, sound, space and time. Most mosquitoes fly around sunset or sunrise, but not in bright light. Generally speaking, it is most suitable at the brightness of 1 10 candles, and it is not suitable for complete darkness or strong light; The length of the light wave does not seem to have anything to do with flying, but the color does, and green is more favorable to flying than red.

Since mosquitoes like dark places, they fly in their ears when they sleep, and when they turn on the lights, they will naturally hide, and their hiding places are usually in small dark corners, especially those corners of furniture and appliances that are not often moved.

In the summer heat, many mosquitoes also like to park on the wooden board, the temperature of the wall is reduced, and if the bed is against the wall, it does not hinder the search inside. If a mosquito net is installed, you will find that the cunning mosquitoes are hiding on the top of the mosquito net, and the top is indeed a number of hidden places.

The moment the lights are turned on, they quickly find a place to land, and because of the hasty landing, the position is not optimal, so they dare not fly unless they are very close. At this time, you just need to look for it, which is near the pillow.

Most mosquitoes are active at night, and they are most active between 5 and 7 p.m., when they enter the room through doors and windows. Once the mosquitoes enter the room, there will always be mosquitoes flying in the ears at night. Of course, there are mosquitoes during the day, and the flower-legged mosquito is a mosquito that likes to be active during the day.

Flapping its little wings, it flies up slowly, with a slight buzzing sound.

Mosquitoes take off by flapping their wings from top to bottom, and the area of the wings is greater than the area from the bottom up, so that the upward lift is obtained.

That's the answer!

Same as any other insect.
