Mosquitoes are an important food source for a lot of other critters. Bats, swallows, dragonflies and spiders are obvious choices, but there are actually a whole lot of waterfowl and other birds that feed on the aquatic larvae. It's one of the reasons some birds fly north in the spring - to feast on the larvae of the mosquitoes that are going to be feasting on them.
They are also pollinators, helping to move pollen around from wildflower to wildflower as they feed on the nectar.
And their role as a disease vector is also important in the ecological picture. It's not a pretty picture, but it definitely has a role in the selective pressures and population dynamics of the organisms in the environment.
