Abstract
Two North American species, Hydropsyche recurvata Banks and H. separata Banks, are known to inhabit the Great Lakes. While H. recurvata is widely distributed in all of the lakes, H. separata seems to be absent in Lakes Superior and Michigan, occurs rarely in Lakes Huron and Ontario but is dominant in Lake Erie. It is suggested that this distribution of the genus Hydropsyche in the Great Lakes is the result of glacial and related geological events. Similarly, the distribution of several H. separata populations in North America may have also been caused by the glaciation. The taxonomy and ecology of Hydropsyche adults and larvae inhabiting lakes is also briefly discussed.
