Following the successful The Orvis Guide to Small Stream Fly Fishing, and written by the best-selling author of The Orvis Fly-Fishing Guide, this is the definitive and complete guide to strategies for fishing insect hatches on trout streams throughout the world. Unlike other books on the subject, it does not focus on the complicated discipline of entomology, but rather on successful fishing techniques that lessen the need for insect identification. This beautifully illustrated and definitive resource explains how to determine what trout are feeding on and how to catch them, with a combination of a reasonable fly pattern, careful observation of the natural environment, and cagey strategies that will fool trout without frightening them. Like The Orvis Guide to Small Stream Fly Fishing, techniques in this guide are for an intermediate-level angler.
