A MOSQUITO LIFE CYCLE
Mosquitoes are small, slender long-legged with two winged-like flies that constitute the family Culicidae. Females of most species are ectoparasites, whose tube-like mouthparts (known as proboscis) pierce the hosts' skin to consume blood. Many of us have had the unpleasant experience of being bitten by a mosquito. Mosquito bites can cause skin irritation through an allergic reaction to the mosquito's saliva - this is what causes the red bump and itching. The bite of the bloodsucking female can transmit a number of extremely serious harmful infection diseases such as malaria and encephalitis.
The word “Mosquito" was formed by mosco and the shortened word -ito) is a Spanish word for "little fly". Thousands of species feed on the blood of various kinds of hosts, mainly vertebrates, including mammals, birds, reptiles, amphibians, and even some kinds of fish. Some mosquitoes also attack invertebrates, mainly arthropods.
The length of the mosquito life cycle varies between species and is dependent upon environmental conditions such as temperature and moisture. However, the life cycle of all mosquitoes is comprised of the egg, larval, pupal and adult stages.
Both male and female mosquitoes feed on plant nectar, the male does not feed on blood, while females extract the blood of its hosts in order to develop and nourish eggs. Most mosquitoes lay their eggs directly into water. Others lay their eggs near bodies of water but not within them.
Eggs will hatch into larvae within 24 to 48 hours. Larvae soon grow to become approximately 5 mm in length. Most larvae breathe through air tubes. Larger larvae can be seen floating just above the surface of infested waters. Without water the Larvae and pupae usually cannot survive. If the water source evaporates before the larvae and pupae within it transform into adult mosquitoes, those young often will die.

Within seven to 10 days, larvae enter the pupal stage. Pupae are also visible upon the surface of the breeding site. After a mosquito is fully developed, it will emerge as an adult from its pupal case. At this time, the new adult stands upon the water and dries its wings to prepare for flight. Adult female mosquitoes will then seek blood from human and other animals on to feed. Females are capable of flying for miles if necessary and can lay over 100 eggs at a time.
Larvae and pupae usually cannot survive without water so all the immature mosquitoes need still, stagnant water in which to develop (complete their larval/pupal stages in). Water quality can range from clean to very polluted and from large bodies of water to rainwater collected in tree holes, old tires, buckets, toys, potted plant trays and saucers, plastic covers or tarpaulins and even places as small as bottle caps.
