According to the CDC, a mosquito has four stages of life. Those are the egg, larvae, pupa, and adult. Some mosquitoes can hatch in as few as two days, while other types of mosquito only hatch after weeks of being laid in standing water. The eggs hatch when they are submerged underwater. They then become larvae which are capable of surviving in the water. The larvae will morph into pupae after five days, and then become adults two to three days later. Only adult mosquitoes have wings. The entire cycle can be completed in as little as eight days.
