How Do Mosquitoes Survive in the Cold?
WouterDuring the cold months, many insects enter a state of hibernation. These insects have evolved strategies to deal with cold weather. In fact, there are several species of mosquito that can survive winter. These insects are a nuisance to humans, but they aren’t always harmful.
In the winter, female mosquitoes go into diapause, a state of suspended development. During this period, the mosquitoes lower their metabolisms, and they store nutrients for later use. They also delay their development until warmer weather comes.
When the weather becomes warmer, the mosquitoes emerge from diapause. They will look for a place to hide. They may lay in a crevice or a hole in the ground. They may also lay in a hollow log or animal burrow.
Some mosquito species have been known to hibernate in icy water or in sheltered areas. Some may hibernate before the first frost of the season. Some may hibernate until the warm weather comes in the spring. Some mosquito species may hibernate for as long as six months.
When the temperature drops below 50 degrees Fahrenheit, the mosquitoes enter a state of diapause. This period is necessary for the mosquitoes’ survival in the colder months.
When the temperature reaches 80 degrees Fahrenheit, the mosquitoes will resume normal activity. They will reproduce and lay eggs. Some species of mosquitoes can lay up to 300 eggs at once. The eggs can survive up to eight months without food.
In the summer, mosquitoes prefer warm weather. During the winter, they prefer homes for shelter. This is because homes provide warm temperatures and a blood meal.
