What is the lifespan of a mosquito depends on species, sex, and environmental conditions, with males living shorter and females living longer, and lifespan varying from few days to several months. For most common mosquitoes, males live about 5 to 10 days, as their primary role is to mate and they do not blood-feed, and they die shortly after mating. Females live longer, about 2 weeks to 2 months in summer depending on species and conditions, as they need to blood-feed to develop eggs and can lay multiple batches of eggs during lifetime, with lifespan shorter in hot, dry conditions and longer in cool, humid conditions. Some species like Culex mosquitoes that transmit West Nile virus live a few weeks in summer. Overwintering females of some species like Anopheles and Culex can live 4 to 6 months, hibernating in sheltered places like basements, barns, or under bark during winter to survive and lay eggs in spring. Mosquito lifecycle includes egg, larva, pupa, and adult stages, with aquatic stages lasting 1 to 2 weeks, and adult lifespan is relatively short. So mosquito lifespan is short, males about a week, females a few weeks to a couple months in summer, with overwintering females living several months, and entire lifecycle from egg to adult can be completed in 10 days to 2 weeks under favorable warm conditions, allowing rapid population growth.
