Aedes aegypti is holometabolous, this type of development stages includes the egg, lava, pupa, and the adult stage. The distinct traits to key out this mosquito are, small palps with white scales. The female mosquito can lay as many as a hundred eggs at one batch, after the eggs are laid down, the eggs develop within two days, and once wet the larvae emerge from the egg shortly after (Christopher, 1960). The larvae then mature over the course of the week or longer, depending on temperature, again while in standing water. The larvae will then go through four larval molts progressively getting bigger. While this is occurring, the larvae will filter feed on any particles or bacteria that may be in the water. The larvae will then enter the pupal stage, the pupae will be on the surface of the water, and breathe with two small tubes. After a few days, or shorter depending on temperature, the pupae metamorphose into an adult. Once the adult emerges, the exoskeleton hardens, and will look for a safe place to dry off.

Aedes aegypti contains six legs and are split into segments, the coxa, trochanter, femur, tibia, and the tarsus. The tarsus can be further divided into multiple tarsomeres (Farnesi, 2012). This specific specie of mosquitos has a lyre-shaped dorsal pattern and white branded legs. The Asian tiger mosquito is similar in terms of appearance, but is a secondary dengue vector, and is adapted further away from humans. Also on the thorax are the wings, while other insects have two pairs of wings, mosquitos have one pair. To help balance the mosquito, halters are developed and act like a gyroscope during flight. The dorsal part of the mosquito is called the scutum. The scutum has distinct scale patterns to identify each species, Aedes aegypti, has a white and black scale pattern. Respiration occurs using spiracles and are found on the lateral sides of the mosquitos’
