In Learning from the Water, René shares his wisdom on the importance of insect stages, the flies for a successful fly box, and how to plan and prepare for a trip to unfamiliar water. Chapters on midges, caddis, Flavs, Callibaetis, Tricos, PMDs, hoppers, beetles, aquatic wasps, and Baetis give solid inside information on each of these important insects as well as the patterns René uses to imitate them, patterns that inspire fly tiers the world over.
