Recognizing that this was an opportunity, I designed nymphs to imitate the four macroinvertebrates I found were common in all the streams I surveyed: flat-headed mayfly (Heptageniidae), brushlegged mayfly (Isonychiidae), common netspinner caddisfly (Hydropsychidae) and finger-net caddisfly (Philopotamidae).
