Although you might find them annoying in the summertime, mosquitoes are an important part of the ecosystem. Mosquito larvae live in the water and provide food for fish and other wildlife, including larvae of other species such as dragonflies. Mosquito larvae eat and recycle microscopic organic matter. Adult mosquitoes are part of the diet of insect-eating animals such as bats, spiders, and dragonflies. They also help pollinate flowers as they drink the nectar. Opinions differ as to what would happen if mosquitoes were eradicated from the face of the Earth.1Some estimate the number of migratory birds nesting between Canada and Russia would drop by more than 50 percent. In the absence of larvae, hundreds of species of fish would need to change their diet to survive. Most mosquito-eating birds would need to switch to other insects. Overall, mosquito loss would be experienced by many species.
