Immature insects (Plecoptera, Trichoptera, and Ephemeroptera) collected from deep water in western Lake Superior

Five species of aquatic insects - two plecopterans, two trichopterans, and one ephemeropteran - usually found in streams or ponds were collected in water 32-100 m deep in western Lake Superior. All appear to be new records for the lake and all were collected from far greater depths than previously recorded for these forms.
