Volume II
After the mayfly family, detailed in Nymphs: The Mayflies, the fly fisher must know the caddisfly, stonefly, and midge populations just as well to catch trout that are keyed in on such insects. Nymphs: Caddisflies, Stoneflies, and Other Important Species gives the reader all the essential information about identifying individual species of these insects throughout their North American range, and then delves into detailed instructions for scores of artificial patterns to imitate them. Few books in fishing literature have focused so closely on so many individual species of the particular genera of aquatic insects in this volume.

And just as in Nymphs: The Mayflies, this book contains numerous stories and anecdotes from Schwiebert's travels that illuminate the selection and use of nymph patterns, and recount great days spent on the water as interpreted through one of the great minds of modern fly fishing.
