The species of Culiseta are large mosquitoes, inhabiting temperate 
latitudes in both Europe and America. The genus contains but a 
small number of species. The larvae inhabit permanent water, the 
eggs of Culiseta proper being deposited in rafts by overwintering 
females. Some of the species take kindly to artificial containers, but 
the adults rarely attack man, preferring larger mammals such as 
horses and cattle. 
Two subgenera may be recognized on the characters of the male 
genitalia, as follows:
