Yellow Fever Mosquito

Aedes aegypti, the yellow fever mosquito, is a small to medium-sized mosquito (3-5 mm), easily identified by the distinctive lyre-shaped pattern of white scales on its thorax and white bands on its legs. A member of the family Culicidae, its lifecycle is typically completed in 7-10 days under warm, humid conditions (optimal 25-29°C), though it can extend up to 3 weeks in cooler temperatures. Females lay desiccation-resistant eggs individually on the inner walls of water-holding containers, just above the waterline. Larvae and pupae exclusively develop in these man-made containers, feeding on microorganisms and organic particulates.

Aedes aegypti is primarily a diurnal and crepuscular biter, with peak activity in the early morning and late afternoon/early evening. Females are highly anthropophilic, exhibiting a strong preference for human blood meals, which they often take multiple times within an egg-laying cycle. This species is an endophagic and endophilic mosquito, frequently resting and biting indoors. Its flight range is very short, typically less than 100 meters, meaning infestations are usually close to breeding sites. They are highly efficient vectors due to their adaptation to human environments and frequent biting habits.
