Larvae aquatic, mainly in standing water (temporary pools, water in discarded containers, saltmarshes, treeholes, etc.); some Anopheles spp. lay eggs in very slow moving streams/brooks.
Mostly spring and summer in temperate climates
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 are tetrapods. • Larvae feed on algae, protozoans, and organic debris filtered from water; a few species prey on other mosquito larvae
Life Cycle
The eggs laid on water surface or above the waterline in areas subject to flooding; eggs hatch in spring; 4 larval instars; larva stage may last from less than a week to over a month, depending on temperature and species; pupal stage typically lasts under a week; adults emerge from pupae at water surface; one to several generations per year.
