Mosquito Life Cycle
Egg Stage
The mosquito life cycle begins with the egg stage. Female mosquitoes lay their eggs in a variety of water sources, depending on the species.
These water sources can range from stagnant ponds, marshes, and temporary rain-filled containers to artificial containers like flower pots, discarded tires, or bird baths.
The number of eggs laid varies by species but can number from a few dozen to several hundred.
Mosquito eggs are typically laid in clusters, forming rafts or clumps that float on the water’s surface.
The eggs of many species are resistant to desiccation and can survive in dry conditions until they are submerged in water.
Larval Stage
When mosquito eggs hatch, they give rise to the larval stage.
Mosquito larvae are aquatic and commonly referred to as “wrigglers” due to their distinctive wriggling motion in the water.
During this stage, larvae feed on microorganisms and organic matter in the water.
They have a head, thorax, and abdomen, with a siphon at the end of their abdomen, which they use to breathe at the water’s surface.
Larvae molt several times as they grow, and the duration of this stage varies depending on factors such as temperature and food availability.
Pupal Stage
Following the larval stage, mosquitoes enter the pupal stage.
Mosquito pupae are often referred to as “tumblers” because of their tumbling, acrobatic movements in the water.
The pupal stage is a transitional phase during which the mosquito undergoes metamorphosis into its adult form.
Unlike larvae, pupae do not feed but rely on air stored in their bodies for respiration.
The pupal stage is relatively short, usually lasting a few days, and it is during this stage that the mosquito transforms into its adult shape.
Adult Stage
The adult stage is the final and most recognizable phase of the mosquito life cycle.
Once the pupa matures, it splits open, and the fully developed mosquito emerges.
Adult mosquitoes have distinctive characteristics, such as their long, slender bodies, long legs, and wings.
In the case of female mosquitoes, they have specialized mouthparts that enable them to feed on blood, a behavior required for egg development.
Males, on the other hand, typically feed on nectar.
The primary purpose of the adult stage is reproduction, with females seeking a blood meal to produce and lay eggs, while males focus on finding mates.
