Nectar is their principal food source. There are over 2500 different species of mosquitoes throughout the world, of which 150 species occur in the United States and 73 species occur in Florida. Each of the species has a Latin scientific name, such as Culex tarsalis. These names are used in a descriptive manner so that the name tells something about this particular mosquito. Modern writers used the name Culex and it is retained today as the name of a mosquito genus.
Mosquitoes can be an annoying, serious problem in man's domain.
They interfere with work and spoil hours of leisure time. Their attacks on farm animals can cause loss of weight and decreased milk production. Each of these stages can be easily recognized by its special appearance. Eggs are laid one at a time and they float on the surface of the water. In the case of Culex and Culiseta species, the eggs are stuck together in rafts of 200 or more.
