Culex pipiens is a species of mosquito commonly referred to as the common house mosquito or northern house mosquito.Native to Africa, Asia and Europe, it is now widely distributed in temperate regions on every continent except Antarctica [1] and is one of the most common mosquitoes found in human habitats in temperate parts of the northern hemisphere.

Eggs hatch only in the presence of water, and the larvae are obligately aquatic, linear in form, and maintain their position and mostly vertical attitude in water by movements of their bristly mouthparts. To swim, they lash their bodies back and forth through the water. [4] [5] During the larval stage, the insect lives submerged in water and ...
Culex quinquefasciatus (originally named Culex fatigans), commonly known as the southern house mosquito, is a medium-sized mosquito found in tropical and subtropical regions of the world. It is a vector of Wuchereria bancrofti , avian malaria , and arboviruses including St. Louis encephalitis virus , Western equine encephalitis virus , Zika ...
Aedes females drop their eggs singly, on damp mud or other surfaces near water; their eggs hatch only when they are flooded. [19] Females in genera such as Culex, Culiseta, and Uranotaenia lay their eggs in floating rafts. [20] [21] Mansonia females in contrast lay their eggs in arrays, attached usually to the under-surfaces of waterlily pads. [22]
The best way to tell if an egg has spoiled is by getting up close and personal with it, Blatner explains. ... To test how old your egg is, lower it (uncracked) into a bowl of water. If it floats ...

Londoners sheltering from the Blitz in underground stations suffered from mosquito bites. This mosquito is found in underground systems around the world. Some authors proposed that it is a new species that evolved since the 19th century in adaptation to human-made underground systems, but it is more likely that it has been in existence for at least hundreds of years and colonized the warm ...
During dry conditions, the virus can remain viable for a number of years in the egg. Mosquitos lay their eggs in water, where they eventually hatch. As water is essential for mosquito eggs to hatch, rainfall and flooding cause an increase in the mosquito population and an increased potential for the virus.
