The life cycle of Aedes mosquitoes consists of four stages (egg, larva, pupa, and adult), with adults emerging anywhere from seven days to several weeks after egg hatching. The adult life span can range from two weeks to a month depending on environmental conditions. The life cycle of Aedes aegypti can be completed within one-and-a-half to three weeks (see figure 1).

The non-feeding or resting stage of mosquito life cycle is (a) larva (b) Pupa (c) Adult male mosquito (d) Adult female mosquito. Mosquito life cycleThe length of the mosquito life cycle differs between species and the conditions of its environment such as temperature and moisture. When eggs are covered by water, the larvae hatch,hang at the surface of the water, and breathe through a snorkel-like siphon at the tip of the abdomen. Larval emergence occurs after rainfall raises the water level in the containers. The adult mosquito emerges onto the water's surface and flies away, ready to begin its lifecycle.

Invasive Aedes are “container breeders” and lay eggs along the waterline of water-filled containers or on the stems of aquatic plants. A larva becomes a pupa. The life cycles of the yellow fever mosquito and the Asian tiger mosquito are very similar. Adults: Like other flies (order Diptera), Aedes taeniorhynchus possess a pair of wings for flight and a pair of knobby halteres for directional perception and stability. Eggs are laid singly on the sides of water-holding containers such as tires, animal watering dishes, birdbaths, flowerpots and natural holes in vegetation (Hawley 1988). %%EOF aegypti and Ae.Albopictus mosquitoes. 2014 ). Under favorable environmental conditions the life cycle is completed in 7-10 days. Eggs hatch within a few days to months when covered with water. They are black and oval with a length of 0.5 mm. It takes about 7-10 days for an egg to develop into an adult mosquito.

Life cycle (egg, larva, pupa and adult mosquito) of Aedes mosquito is shown on this movie. The entire life cycle, from an egg to an adult, takes approximately 8-10 days. There are four larval stages that feed on organic material that they filter out of the water with their mouthparts. The mosquito goes through four separate and distinct stages of its life cycle which are as follows: egg, larva, pupa, and adult. It is abundant in neotropical regions, where environmental factors (e.g., rainfall, temperature, and relative humidity) favor its life cycle (Eisen et al. Aedes mosquito life cycle begins with the larvae hatching when water inundates the eggs as a product of rains or the addition of water by people. The eggs of Aedes aegypti are smooth, long, ovoid shaped, and roughly one millimeter long. When first laid, eggs appear white but within minutes turn a shiny black. They shed their skin four times growing larger after each molting. This happens when water (from rain or a sprinkler) covers the eggs. The mosquito goes through four separate and distinct stages of its life cycle: Egg, Larva, Pupa, and Adult. Mosquito eggs can even survive a winter in the southern United States. A mosquito egg hatches into a larva. Adults: when the adult emerges from pupa, it rest for a while on the pupal skin then flies away.
