Do Mosquitoes Need Water to Survive?
WouterDespite the fact that mosquitoes are not known to feed on humans, they can be found throughout the world. In fact, there are over two hundred species of mosquitos identified in North America. Each species has its own unique way of laying eggs. Some mosquitos lay eggs on the surface of stagnant water, while others prefer marshes and tall grasses.
Mosquitoes have a four-stage life cycle. During this stage, the larvae develop. They live in water for about ten days, during which time they feed on algae and other microorganisms. The larvae need air to survive, so they move up and down the water column to breathe. The larvae then pupate. Depending on the species, the pupae can become mosquitoes. They can remain in the water for a few days, but will die if they are exposed to dry conditions.
Mosquitoes have specialized structures called breathing siphons. These are like straws that go up to the water’s surface. Some mosquito larvae pierce the roots of water plants in order to gain air. Other larvae use saw-like structures to obtain air pockets.
Mosquitoes need a variety of water-based foods to thrive. They may feed on blood, juice from fruit, and honey-dew. They will also eat microscopic plants and animals in the water. Their mouthparts carry hollowed-out bristles that allow them to taste and smell specific molecules.
Mosquitoes lay eggs on the surface of water or on the sides of containers. Some species of mosquitoes are also known to lay eggs on the water bottle caps. Depending on the species, they can lay hundreds of eggs during their lifetime.
