why do mosquitoes exist

Mosquitoes exist primarily due to their ecological roles and evolutionary success. They serve as pollinators by feeding on flower nectar, which helps in plant fertilization. They are also a vital part of the food chain, serving as prey for many species of birds, bats, fish, amphibians, and insects. Additionally, mosquito larvae contribute to nutrient recycling by consuming organic matter in aquatic environments. Female mosquitoes require blood meals mainly to obtain protein for egg development, while males feed exclusively on nectar. Although they are often seen as pests, mosquitoes have evolved to fill specific ecological niches that support biodiversity and ecosystem stability. Their existence is not for a specific "purpose" but rather a result of evolutionary adaptation and the roles they play in their ecosystems.
