The adult emerges from the pupal case after about two days.
The adult ingest air to expand their abdomen. This splits the pupal
case allowing the adult to emerge head first.
The adults move from the surface of the water to cool, moist areas
where they mate and begin the life cycle again.
Males and females mate shortly after emerging from their pupal
cases. Male mosquitoes live only a few days after mating, feeding on
plant nectar until they die.
The fertilized female must have one to three blood meals to allow
her eggs to mature for laying.
Each blood meal takes two to seven days to digest.
The female can produce up to 200 eggs per clutch after three blood
The number of eggs produced depends on the amount of blood
Each female is capable of producing up to five clutches in her
Pupa to Adult transition takes approximately 2 days to complete.
Aedes aegypti females usually lay their eggs singly, though they
can be laid in a raft.
Eggs are laid near water where flooding and raised water levels
Initially white eggs turn a shiny black color a few minutes after
Eggs can survive several months if desiccated. When wet, the
eggs hatch into larvae in two to seven days based upon the
climate and temperature.
Egg to Larvae transition is approximately 2-7 days.
Mosquito larvae are commonly called "wrigglers" because of
their behavior of wiggling when disturbed.
Larvae hang head down from the surface of the water with their
posterior breathing tube (siphon) extended above the surface for
The larvae feed on algae and microorganisms filtered from the
water by their mouthparts.
The larva quickly moves through the first three stages (instars)
as they grow rapidly and require molting.
The larva stays in the fourth instar stage longer than the
previous stages, usually three days under ideal conditions.
Ae. aegypti larva can survive up to a month under cold
Egg to Larvae transition is approximately 2 days.
After reaching maturity, the fourth instar enters the pupal
The pupa is located on the surface of the water where it
breathes through a pair of air tubes or trumpets.
This stage of the mosquito is commonly referred to as a
"tumbler." The pupae of mosquitoes are mobile and respond to
The pupae do not feed.
They take about two days to mature.
Inside the pupal case metamorphosis occurs changing the
larval form into an adult with legs, wings, compound eyes, and
Larva to Pupa transition is approximately 2 days.
