Depending on the species mosquitoes can grow to 4 to 6 mm long. Only the females bite and suck blood, which they need for reproduction. The males do not bite. Usually the mosquito larvae grow in stagnant (dirty) and shallow water.
Moisture and heat speed up the developing cycle of the larvae. Mosquitoes are mostly active in the time between dusk and dawn - on warm humid days in the afternoon as well. In the daytime they usually hide in moist shady places such as hedges and woodland, or in houses. They are responsible for transmitting the commonest infectious diseases throughout the world. Mosquito species such as Aedes, Anopheles and Culex are carriers of dangerous diseases such as yellow or dengue fever (Aedes), malaria, virus encephalitis, filariasis (Anopheles), meningitis and filaria (threadworm) diseases (Culex).
