Do mosquitoes hibernate in winter?

In the vast majority of cases, mosquitoes do not hibernate in the true sense of the word like bears. In cold environments, mosquitoes enter a state of dormancy, which is often called "overwintering" rather than hibernation. Mosquitoes in the overwintering state will slow down their activities and look for relatively warm places during the cold season, such as underground caves, tree holes or other hidden places, to avoid extreme low temperatures.

In warm areas, adults of some mosquito species seek warm places to escape cold weather, while other species overwinter as their larval stage (mosquito larvae) in water, waiting to hatch into adults when temperatures warm.

Although mosquitoes reduce activity during cold periods, not all mosquitoes survive the winter. Adults of some mosquito species die during the cold season, and their eggs or larvae overwinter on the ground or in water and hatch when temperatures warm.

It is important to note that in some areas (such as the tropics or warm urban areas), the mosquito life cycle may continue almost year-round due to relatively warm temperatures, and active mosquitoes may still be seen even in winter.
