Various approaches used in teaching aquatic entomology are presented. An introductory paper surveys methods used in North America for teaching taxonomy of aquatic insects. The subsequent papers can be grouped into: (1) primarily classroom/laboratory exercises, including data simulation in statistical evaluation, nitrogen transformations in stream sediments, stonefly drumming behavior, a method for projecting images of live aquatic insects, and demonstrations of aquatic insect behavior; (2) primarily field exercises, including the use of study streams in Michigan and winter field trips in Ontario; and (3) combined classroom/laboratory and field exercises, including analyses of species associations and species-area patterns of insects on stream rocks, development of self-instructional modules which demonstrate principles of aquatic entomology to undergraduate students and graduate-level students and demonstrations of stream watershed community processes.
