Aedes col?zmu,Gs is widely distributed throughout the North-
ern forests of the United States, Canada, Northern Europe,
Siberia and Alaska. It is said to remain in the shade and bites
whenever opportunity offers, though it attacks most fiercely
just after dark. The species is, single brooded, the adults liv-
ing till late in the season (August). The larval habitat is
normally early spring pools filled with melting snows, though
I have taken them in swamps and marshes. The adults appear
very early, the latter part of April (Central New York).
