The picture illustrates the life cycle of an female insect called mosquito.
In general, the process includes a series of stages like a lifespan of female mosquito, but involves seven main steps which starts with hatching eggs and ends with a fully grown mosquito lays eggs.
To begin with, eggs are produced in the first week. About seven days later, the first larval stage begins, the eggs are now in a long thin shape. For the next two weeks, the larva moves to stage two and three with a bigger size. Week five is the last stage of the mosquito in a larval shape and it is much larger than it used to be in the first stage.
Following, molting is occurred before the larva moves to pupal stage. In week six, there are significant changes as a mosquito is forming in this stage. After one to two weeks, the pupa develops to an adult mosquito and it can live up to fourteen days until its last stage. Finally, the female lays eggs in the water and the life cycle will start all over again.
