It usually takes around 7 to 14 days for an egg to develop into an adult, provided the weather conditions are suitable for mosquito development.
All mosquito species have four distinct stages during mosquito life cycle:
- Egg: hatches when comes in contact with water.
- Larva: (plural: larvae) “wriggler” lives in water; molts several times; most species surface to breathe air.
- Pupa: (plural: pupae) “tumbler” does not feed; stage just before emerging as adult.
- Adult: flies short time after emerging and after its body parts have hardened.
The first three stages develop in water, but the adult mosquito is an active flying vector.
Only the female mosquito bites and feeds on the blood of animals or human.
- The female mosquito lays the eggs on or near water, soil, and at the base of some plants in places that may fill with water once she obtains a blood meal. The eggs have the competence to survive dry conditions for a few months. There are some mosquitoes who lay their eggs separately, whereas, some have the tendency to lay eggs in rafts of 200 or more. These eggs mostly hatch within 48 hours.
- The eggs hatch in water from which a mosquito larva or “wriggler” emerges. The time required for these eggs to hatch is mostly dependent on factors like water temperature, food and type of mosquito. The Larvae, developed, have siphon tubes that aids with breathing and hanging from the surface. Larvae go through four growing stages, called instars, and the fourth instar stage develops into a pupae
- The larva lives and feeds in the water & then later develops into the third stage of the life cycle, known as a pupa or “tumbler.” The pupa also lives in the water but no longer feeds. The pupal stage is a resting and non-feeding phase which makes the juvenile develop into an adult. Pupae look like little balls in the water. It takes about two days before the adult is formed and development is complete. The pupal skin splits from which an adult mosquito emerges.
- Finally, the mosquito emerges from the pupa case after two days to a week in the pupa stage. This newly emanated adult rests on the surface of the water for a short time that hardens its body parts. The wings must spread out and dry before the mosquito can fly.
