There are three main forms of mosquitoes in winter, namely, adults, larvae (wigglers) and eggs. For example, culex pipiens pallens and anopheles sinensis live through the winter as adults, while most of the anopheles minimus and culex tritaeniorhynchus live through the winter as larvae (larvae), and most of the eggs live through the winter as aedes albopictus. During the wintering season, large Numbers of mosquitoes die, and only a few survive until the following spring. The mosquitoes that survive the winter are the least mobile and most vulnerable.

But if the mosquito has enough energy and finds a suitable hiding place, it will hardly freeze to death. But at low temperatures, the mosquitoes' mobility declines.

Have someone abroad experiments, in - 50 ℃, the mosquito can live for a long time. In much of the north, low temperatures during the winter can cause mosquitoes to hibernate, but their body fluids don't freeze. "There's something in the body fluids of mosquitoes, like antifreeze in gasoline."

Mosquitoes stop breeding in winter when temperatures drop. Adult mosquitoes gather in warm, dark places to hide, and their metabolism drops to a very low level. Indoors, mosquitoes may hide in the bathroom, in the corner of a flower pot, under a bed or in the crevices of furniture. Outside, even piles of fallen leaves and crevices in the bark can be wintering spots for mosquitoes.

So what kind of mosquito can't survive the winter? And the person is same, "eat" not satisfied, "live" not warm mosquito, spend chill hard. The mosquito that cannot successfully overwinter, it is before entering winter more, fail to store enough energy. Not enough food, not enough food. Another is the inability to find suitable wintering sites. Because birds, frogs, bats and other natural enemies of mosquitoes, in the winter will reduce activity or enter the dormant period. Therefore, as long as "eat enough to live warm", mosquitoes can wait until "spring flowers". In the north, indoor heating, mosquitoes overwintering "conditions", and therefore improve.
