In the transition phase from larva to pupa the respiratory tubes close over. This means that the larva is left unable to breathe. However, a surprising development occurs and two new windpipes appear on the front of the pupa. Once more the mosquito manages to stay alive due to a development programme specifically designed for it. The larva starts breathing by elevating these two new windpipes to the surface of the water.

The pupae stay close to the water surface in order to breathe. Although they move very fast, they have no nutritional needs. The pupal phase comes to an end in 3-4 days.

During the pupal stage, the wings and legs of the mosquito become fully formed inside the cocoon floating in the water. It is extremely important for the structures necessary for flying to be formed perfectly underwater. The perfect formation of structures that enable a creature to fly in a different environment whilst submerged in a cocoon under the water is just one of the examples of supreme creation.

Towards the end of the pupal phase the mosquito becomes much darker in colour and the skin becomes more transparent. Within five days, the pupa's skin splits and the mature mosquito is ready to emerge from the water. This moment is a show of astonishing expertise, for the young mosquito leaves the floating pupa without touching the water. It has to be able to do this, as it cannot fly if its wings get wet.

The wings and legs have already completed their development during the pupal phase and are ready waiting inside the pupa till the time for their use.

The mosquito overcomes difficulties

Just before emerging from the cocoon, the pupa takes a breath and expands. This expansion causes the cocoon to split, starting from the head. This is an important detail, because if the splitting started from the bottom rather than the top, the mosquito would not come to the surface of the water and would drown.

At this stage, the mosquito preparing to emerge faces great danger. If water got into the splitting cocoon, it would mean the end of the mosquito. However, the necessary precautions have already been taken to prevent this danger. The head of the splitting cocoon is covered with a sticky substance that prevents the head of the mosquito from coming into contact with the water. This fluid, in common with the fluid already used by the animal in the "snorkel," is water-repellent. If it were not for this special liquid in the head region, the splitting cocoon would fill with water. The mosquito's wings and body would get wet and it would sink together with the cocoon.

That's not the only danger the mosquito faces when emerging from the cocoon; new difficulties await it. Let's give some thought to the situation of the mosquito as it attempts to extract itself from the tight-fitting cocoon enclosing it: If it loses its balance, the cocoon may turn upside down. The mosquito may come into contact with the water as it emerges and get wet. Both possibilities would mean death by drowning for the mosquito.

The mosquito emerges from its underwater world with everything it needs for the outside world: Its wings are formed underwater. The special blood-sucking mechanism is formed underwater. The special fluid that prevents the blood clotting and numbs the tissue of the victim is formed underwater. The special receptive system that detects the location of prey is formed underwater. The superb perceptive skill that is even able to differentiate the frequency of the female’s wing beat is formed underwater. Vision is also developed underwater. The perfectly created mosquito leaves the water and sets foot in the outside world, as if coming from a state of non-existence into our world. It is God Who knows every form of creation and creates in perfection.
