There are totally different species of mosquitoes (Anopheles, Aedes, Culex) and these have utterly totally different preferred habitats, occasions when they are active and varieties of bite. The lavae that produce the adults develop in areas of stagnant water (receptacles, reservoirs, ponds, lakes, and many others.).
