In warm seasons, eggs can hatch in about three days and begin to eat tiny microorganisms and protozoa growing in water. They lean on two air holes at the end of their bodies and suck air near the water surface. After molting, the old man finally stopped eating east and west, reduced his activities and became a pupa. After about two or three days, the pupa surfaced, shed its skin and emerged as an adult.
Extended data:
Mosquitoes generally start to go out in May and reach the peak in the middle and late August. When the climate gets cold in autumn and the temperature drops below 10 degrees Celsius, we stop breeding, go into hibernation without eating, and come out after waking up the next spring.
People's favorite temperature is about 30 degrees Celsius, which is unbearable. Our living and breeding environment must have water, so groundwater, stinking ditches, sewers and mosquitoes all choose their objects by smell.
Scientists' research shows that mosquitoes bite people selectively, and those who can bring mosquitoes rich cholesterol and vitamin B are most favored by mosquitoes. Mosquitoes use their sense of smell to find the object that suits their "appetite" best from the crowd. Cholesterol and vitamin B are essential nutrients for the survival of annoying insects such as mosquitoes, and they cannot produce these substances by themselves.
Mosquitoes have a strong sense of smell. When humans exhale carbon dioxide and other smells, these smells will spread in the air. These smells are like the bell for dinner, telling mosquitoes that a good meal is just around the corner.
When a mosquito tracks a target, it always twists and turns with the smell of people's breath until it touches the target and then falls on the skin, patiently looking for a "breakthrough". Finally, directly insert the "needle tube" into the skin to suck blood for 8- 10 seconds.
