Male (left) and female (center and right) Ae. aegypti E.A. Goeldi, 1905. Aedes aegypti is a 4-to-7-millimetre-long (5 ⁄ 32 to 35 ⁄ 128 in), dark mosquito which 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. Females are larger than males.
All mosquitoes drink nectar from flowers; females of some species have in addition adapted to drink blood. The group diversified during the Cretaceous period. Evolutionary biologists view mosquitoes as micropredators , small animals that parasitise larger ones by drinking their blood without immediately killing them.
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. Most species occur in forests. It includes the largest known species of mosquito, at up to 18 mm (0.71 in) in length and 24 mm (0.94 in) in wingspan. [1]
There are more than 3,500 species of mosquitoes worldwide, found everywhere except Antarctica. Some become disease vectors transmitting malaria, yellow fever, Zika fever, dengue and other diseases.

The males are roughly 20% smaller than the females, but they are morphologically very similar. However, as in all mosquito species, the antennae of the males in comparison to the females are noticeably bushier and contain auditory receptors to detect the characteristic whine, almost inaudible to humans, of the female. The maxillary palps of the ...
Before the male mosquitoes are released, an X-ray machine sterilizes them. If the zapped males mate with a female, her eggs won't hatch. Allen J. Schaben / Los Angeles Times
This small population makes it difficult to produce enough larvae to prey on the much larger populations of vector mosquitoes. Tx. rutilus thus cannot single-handedly control mosquito populations, but must be used in combination to other mosquito control methods such as insecticides. Care must be taken in the timing of applying pesticides as ...
