West Nile virus (WNV), St. Louis encephalitis (SLE), La Crosse encephalitis (LAC) and eastern equine encephalitis (EEE). What family do mosquitoes belong to? Culicidae The three egg laying patterns

Aedes eggs The eggs of Aedes, Psorophora and Orthopodomyia species are deposited individually out of the water, and they are adapted to withstand desiccation (being dry) until the area is later flooded and the eggs hatch.
