We need mosquitoes because they play several important roles in ecosystems despite being pests and disease carriers. Mosquitoes contribute to nutrient cycling by breaking down organic matter in aquatic environments during their larval stage. They also serve as a vital food source for many animals, such as fish, amphibians, birds, bats, dragonflies, spiders, and other insect-eating creatures. Furthermore, mosquitoes act as pollinators by feeding on nectar and inadvertently transferring pollen, helping with the reproduction of various plants. They also influence ecological balance and natural selection by selectively biting hosts, which may affect population dynamics of animals. Therefore, mosquitoes are integral to maintaining ecological balance and supporting biodiversity.
