The Pocketguide to Western Hatches has all the trout-relevant bugs that hatch on stillwaters and streams out here west of the Rockies. For each bug, there are little tidbits on life cycle and how to identify, and a few pattern suggestions for matching the hatch. From skwalas to golden stones, and caddis to scuds, they're all in here and described in detail. Dave has also kindly written a few tips in the beginning of the book on how to fish different types of hatches. Even if you're a champion caster, knowing which bugs to fish and where is paramount. Whether you're a novice angler looking to bone up on some amateur entomology, or a veteran angler looking to dial in all the fantastic hatches we get out here in central Oregon, there's something for you to learn in this book.
