The female mosquito drinks the blood and uses it to produce as many as two hundred fifty eggs. The
insect leaves the eggs in any standing water.
The eggs produce worm-like creatures called larvae in two days to a few months. However, some
eggs can stay in water for years until conditions are right for development. The larvae feed on
organisms in the water. After four to ten days, they change again, into creatures called pupas. The
pupas rise to the surface of the water. Adult mosquitoes pull themselves out of the pupas and fly
away.
