It is the key step for the mosquito to move from the aquatic environment to the air. In this phase, which lasts a few days and even hours, in certain species of mosquitoes a series of metabolic and physical transformations takes place (metamorphosis).
During this period the pupa does not feed, it has respiratory tubes that isolate it from the aquatic environment and is mobile.
At the time of emergence of the adult, the exoskeleton breaks and the adult remains for a few moments on the surface of the water until it is ready to fly, thus initiating the colonization of the air environment.
Depending on their number and the species in question, the problem generated by their presence appears at this time.
