Mosquitoes copulate while flying during the night. 0 Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features.

Pupa: The pupal stage is a resting, non-feeding stage. Adult: An adult emerges from a pupa when the skin splits after a few days. The female mosquitoes remain alive for one to several months. In some species of mosquito, the females feed on humans, and are therefore vectors for a number of infectious diseases affecting millions of people every year. When development is complete, the pupal skin splits and the mosquito emerges as an adult. Mosquitoes are a vector agent that carries disease-causing viruses and parasites from person to person without catching the disease themselves. That is why, its life is very short (2 to 7 days). %%EOF On each lateral side, it bears a large compound eye and a small simple eye or ocellus. It does not store any personal data. Only the female mosquitobites and feeds on the blood of humans or other animals. Other mosquitoes lay their eggs on damp soil that will be flooded by water. In the beginning, the eggs are white, but gradually these acquire a grey colour.
