Here is a picture of a Mosquito as we are looking at its Life cycle.
The mosquito goes through four separate and distinct stages of its life cycle: Egg, Larva, Pupa, and Adult-- Egg to Larva 24 to 48 hours, Larva to Pupal 7 to 10 days, Pupal to Adult 2 to 7 days. The length of the mosquito life cycle varies between species and is dependent upon environmental conditions such as temperature and moisture, and it can range from 4 days to as long as a month. People drinking beer have been shown to be more attractive to mosquitoes, because it increases the ethanol in your sweat, and raise your body temperature. They can be trapped easily by placing cups filled with cheap beer or use active yeast with the sugar.
