This genus contains more than half (65) of all North Ameri-
can species of mosquitoes. It is world wide in distribution
and all the species bite, attacking mainly during the evening
though many are nocturnal and some primarily diurnal. When
disturbed or in favored situations, the great majority will
readily attack during the day. In North America, the majority
of our species are northern in distribution and the countless
hordes of arctic mosquitoes belong in this genus. The northern
species are lovers of woodlands, marshes, prairies, and moun-
tainous areas. Other species are coastal forms breeding in salt
marshes and such species become veritable plagues. Still others
breed in water found in tree-holes, rock pools and some have
become domesticated (A&es agypti) breeding only about hu-
man habitations. Only one species (Aedes agypti) is known
as a vector of disease (Yellow fever and dengue).
