Which of the following is NOT a stage in the mosquito life cycle?

• A. Egg
• B. Larva
• C. Cocoon
• D. Pupa

Answer: (C)

The correct answer to the question is the stage referred to as "Cocoon." In the mosquito life cycle, there are four main stages: egg, larva, pupa, and adult.

Mosquitoes begin their life as eggs, which hatch into larvae (often called "wrigglers"), that then develop into pupae (also known as "tumblers"). After a phase of development, pupae emerge as adult mosquitoes.

While many insects, such as butterflies and moths, do go through a cocoon stage during their transformation, mosquitoes do not form a cocoon. Instead, they transitions directly from the pupal stage to adulthood without a protective covering. This distinction is important in understanding the complete life cycle of a mosquito and highlights the specific developmental stages that all mosquitoes undergo.
