Aedes aegypti, the yellow fever mosquito, is a mosquito that can spread dengue fever, chikungunya, Zika fever, and yellow fever viruses, and other diseases. The mosquito can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax. This mosquito originated in Africa,[2] but is now found in tropical and subtropical regions throughout the world.[3] The average wing length of female Ae. aegypti mosquitoes varies greatly (1.67–3.83 mm in a Peruvian habitat).[4]
