Explanation of Names
Culicidae Meigen 1818
mosquito 'small fly'
174 spp. in 14 genera in our area(3), >3700 spp. in 46 genera and 145 subgenera worldwide, arranged in 2 subfamilies(2)(4) [many subgenera, esp. in the Aedini, are often treated as separate genera -- cf.(1)]
3-15 mm
Wings with scales on veins and along margins; legs and proboscis long; antennae with 6 or more segments, plumose on males and short-haired on females

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.
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 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.
Eggs (1), egg rafts (2), larvae (3-4), pupa (5), adults: female (6-7), male (8-9)

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.
