describe the life cycle of a mosquito.?

Answer 1

The mosquito goes through four separate and distinct stages of its life cycle and they are as follows: Egg, Larva, pupa, and adult. Each of these stages can be easily recognized by their special appearance. There are four common groups of mosquitoes living in the Bay Area. They are Aedes, Anopheles, Culex, and Culiseta.

Egg : Eggs are laid one at a time and they float on the surface of the water. In the case of Culex and Culiseta species, the eggs are stuck together in rafts of a hundred or more eggs. Anopheles and Aedes species do not make egg rafts but lay their eggs separately. Culex, Culiseta, and Anopheles lay their eggs on water while Aedes lay their eggs on damp soil that will be flooded by water. Most eggs hatch into larvae within 48 hours.

Larva : The larva (larvae - plural) live in the water and come to the surface to breathe. They shed their skin four times growing larger after each molting. Most larvae have siphon tubes for breathing and hang from the water surface. Anopheles larvae do not have a siphon and they lay parallel to the water surface. The larva feed on micro-organisms and organic matter in the water. On the fourth molt the larva changes into a pupa.

Pupa: The pupal stage is a resting, non-feeding stage. This is the time the mosquito turns into an adult. It takes about two days before the adult is fully developed. When development is complete, the pupal skin splits and the mosquito emerges as an adult.

Adult: The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its parts to harden. Also, the wings have to spread out and dry properly before it can fly.

The egg, larvae and pupae stages depend on temperature and species characteristics as to how long it takes for development. For instance, Culex tarsalis might go through its life cycle in 14 days at 70 F and take only 10 days at 80 F. Also, some species have naturally adapted to go through their entire life cycle in as little as four days or as long as one month

Answer 2

Mosquitos are insects known as flies. Flies have larva called maggots, but in the mosquito the maggots are aquatic.

The life cycle begins with a female mosquito attracting a male by the noise her wings make. This is a precise frequency which attracts the male. After mating, her fertilized eggs won't develop any farther until she has ingested blood. She locates prey by the carbon dioxide they exhale as they breathe. This can be a bird, a monkey or a person. Unlike a housefly, her mouthparts are a long tube with a drill on the end. She pierces the skin and then injects saliva. The saliva contains a special anti-clotting enzyme which keeps the blood liquid.

When the eggs are mature, the female lands on the water's surface and lays her eggs. The female can walk on water because she is light enough not to break the surface tension. The eggs are laid vertically in a raft of twenty eggs or so. They hatch into aquatic larvae. These feed on algae and decomposing material. Some species have special larva which develop into cannibals. These eat the other larva if there are too many. Other species have larva which only eat other mosquito larva. These mosquito preditors are used in mosquito control.

Mosquitos undergo a complete metamorphosis. Like butterflies, they have an egg, larva, pupa and adult stage. The pupa is a resting stage in which the larva rearranges its body into an adult form. When the adult forms, it breaks out of the larval shell, and with the help of the water's surface tension, rests for a moment, spreads its wings and flies away. The cycle then begins again.

Answer 3

where were the eggs deposited

Answer 4

One of the first part of the cycle is to get blood. I don't know if they have sex before or after the blood. Then the female needs still water to lay her eggs in. In your house it is probably the commode ,and then u just flush them down the sewer where they are exposed to every thing,and if they live they could carry anything.

Answer 5

It hatches in water, grows up into a flying pest, eats, lays eggs in water, then it dies.

Answer 6

they live for 21 days or 3weeks
