Although mosquitoes are small in size, they have a huge impact on humans. They often make us restless and unable to sleep. Like flies, mosquitoes carry diseases and are extremely annoying insects.
Only female mosquitoes suck blood. Mosquitoes are divided into male and female, and generally they like to suck nectar or plant juices. During the breeding period, female mosquitoes must suck blood to promote the maturation of eggs and then produce the next generation. Therefore, it is the female mosquito that bites, not the male mosquito. Because mosquitoes have antennae and bristles on their heads and legs and are very sensitive to humidity, temperature, and sweat, they often bite people who sweat easily and don't like to bathe. While sucking blood, female mosquitoes can transmit some diseases to humans.
A mosquito sucks about a few thousandths of a milliliter of blood with each bite. After each meal, they move within a few kilometers of their birthplace. After a person is bitten, the skin often develops symptoms of swelling and itching. This is because mosquito saliva contains a special substance that has the effects of dilating blood vessels and anti-coagulation . This effect makes the blood It is more likely to flow to the bite site, causing the skin to become red and swollen.
The life of a mosquito goes through four stages: egg, larvae, pupa, and adult. The eggs are laid by adults on the water surface and hatch into aquatic larvae - larvae after a day or two; the larvae will undergo four molts and then grow into pupae; the pupae will float on the water surface and drift with the current. After wandering for two or three days, the pupae will Cracks will appear in the epidermis, and larvae will be born. The life of a mosquito is very short. The survival period of female mosquitoes is 3 to 100 days, while the survival period of male mosquitoes is only 10 to 20 days.
