Why do female mosquitoes bite people, but male mosquitoes don t?

The mosquito that bites is a female mosquito. Male mosquitoes do not bite. Female mosquitoes must be nourished in order to reproduce the next generation, and human blood is the best supplement.

It cuts through a person's ** with a fine needle on its mouthparts, and sucks blood while injecting saliva into the person's veins. And its saliva carries many bacteria, which can cause people to contract a variety of diseases.

Medical studies have shown that the mosquitoes that will ring in the ears are male mosquitoes, and they generally do not bite people. They don't suck human blood.

The mosquitoes that don't scream are female mosquitoes, and they bite people! So those mosquitoes that bite people are very cunning. They will bite you before you know it.

Male mosquitoes do not suck blood and survive on grass juice and the like.

In fact, female mosquitoes also survive by eating grass, and the reason why they suck blood is necessary to give birth to offspring. They can only reproduce by sucking blood, so the female mosquitoes that suck blood are the female mosquitoes, and the male mosquitoes live in the grass.

There is also a big difference between male and female mosquitoes in terms of physical characteristics, and you will find it if you look closely.

Female mosquitoes need blood to ovulate, and they can suck blood every night, each time they can suck more blood than they weigh. Male mosquitoes do not suck blood, they only suck the sap of plants, so they generally do not enter the house. Only after autumn when the weather is cold will they run indoors to escape the cold.

The lifespan of mosquitoes is generally about one to two months.

Males have many dense long hairs on their antennae, like a small feather duster, and their jaws are short and thin. Such a thin jaw cannot pierce a person's **, so it cannot suck human blood. So in general, male mosquitoes do not bite people and cannot suck human blood.

Mosquitoes belong to the family of insects of the order Diptera, and there are about 3,000 species in the world. It is a small flying insect with stinging and sucking mouthparts. Usually females feed on blood, while males suck the sap of plants.

Blood-sucking female mosquitoes are intermediate hosts for other pathogens such as dengue, malaria, yellow fever, filariasis, Japanese encephalitis, etc.

In daily life, every summer, there are many mosquitoes, especially in rural areas, mosquitoes are particularly powerful, they love to stare at people, people also hate mosquitoes, every time they are stared at by mosquitoes, there will be extra-large bags, so the question is, is the biting mosquito male or female?

Generally, the mosquitoes that bite people are female mosquitoes, male mosquitoes usually only drink dew, and the purpose of female mosquitoes biting people is because mosquitoes cannot produce certain proteins for reproduction on their own, and these proteins can be obtained from the blood pressure of mammals, so mosquitoes will come to bite people, and of course they will bite other mammals. After the mosquito has sucked the blood, it will find a place to break down the blood and use the migratory proteins to produce egg cells, a process that takes about 3-4 days, and then the mosquito may go to lay eggs, or continue to suck blood until its needs are satisfied.

The biting mosquito is a female mosquito, usually the female mosquito needs to reproduce, only usually biting, can obtain the protein of the offspring from the blood absorbed, so as to lay eggs.

Male mosquitoes do not bite.

Because the male mosquito is degraded or almost disappeared from the upper and lower jaws, it cannot pierce the host's **, so it feeds on the sap of plants in nature.

Catch the biting mosquito carefully and look at it carefully with a magnifying glass. At this time, it will be seen that its head has two antennae similar to goldfish algae, and the hairs of the antennae are sparse. If you look closely at its mouthparts, they look like a needle.

If you look closely, this needle is made up of 6 thin mouth needles, two of which are for the upper jaw, two for the lower jaw, and one for the tongue and one for the lips. When sucking blood, the jaw is pierced first, and other mouth needles are extended into the wound until the blood vessels suck human blood. If you catch a few more blood-sucking mosquitoes, you will find that the structure of their mouthparts and antennae is the same, and it turns out that they are all female mosquitoes - female mosquitoes.

It seems that male mosquitoes cannot be caught among the mosquitoes that feed on human blood. In this case, you can use a basin with soapy water or use an insect trap net to catch some mosquitoes in the grass. Then use a magnifying glass to observe their antennae and mouthparts.

In addition to the same structure as the above-mentioned mosquitoes, there is another type of mosquito with many dense long hairs on its antennae, like a small feather duster. If you look at its mouth again, you will see that its jaw is short and thin. Such a weak jaw cannot pierce a person's **, so it cannot suck human blood, which is a male mosquito.

So in general, male mosquitoes do not bite people and cannot suck human blood.

If the female mosquito does not suck blood, the eggs will not be able to mature. After mating, every time the female mosquito sucks blood, it flies to the surface of the water to lay an egg. After several egg lays, the female mosquito dies. There are also female mosquitoes that can overwinter indoors.

The nutrients of male mosquitoes generally come from nectar, plant juice and dew, etc., and their lifespan is very short, generally only 6 7 days. Most male mosquitoes die soon after mating with females.
