Habitat
Larvae are aquatic, developing mainly in standing water (temporary pools, water in discarded containers, saltmarshes, treeholes, etc.); some species of Anopheles lay eggs in very slow moving streams/brooks.
Season
Mostly spring and summer in temperate climates
Food
Male and female adults feed on nectar and plant juices and only females feed on blood because a blood meal is usually required for development of eggs. Hosts may include amphibians, birds, reptiles, and mammals.

Larvae feed on algae, protozoans, and organic debris filtered from the water. However, a few species are predaceous on other mosquito larvae
Life Cycle
The eggs are laid either on the surface of standing water or above the waterline in areas subject to flooding; eggs hatch in spring and larvae complete 4 stages of development before pupating; larva stage may last from less than a week to more than a month, depending mostly on temperature and species; pupa stage typically lasts less than a week; adults emerge directly from pupae at the water surface; from one to several generations per year, depending on species and latitude.

Remarks
Female mosquitoes are vectors of major diseases, including malaria [caused by a protozoan], yellow fever [virus], filariasis [nematode], dengue [virus], and certain types of encephalitis [virus].
Carbon dioxide exhaled by animals attracts female mosquitoes looking for a blood meal.
