Book Description
Although the concept of “matching the hatch” has been central to flyfishing for 150 years, it has been used almost exclusively for dry flyfishing. With Common Nymphs of Eastern North America: A Primer for Flyfishers and Flytiers, Caleb Tzilkowski and Jay Stauffer Jr. take trout enthusiasts in another hatch-matching direction—to the year-round underwater nymph “hatch,” which, in most cases, constitutes 90 percent of trout diets. Successful flyfishers have at least rudimentary knowledge of the organisms that artificial flies imitate. The relatively few and very best anglers are expert at identifying and imitating nymph appearances and habits. A major hurdle to becoming expert at nymph matching is overcoming two major limitations that make these animals difficult to locate, capture, and identify: first, nymphs live underwater, sometimes burrowed into the stream bottom, and second, many nymphs are nearly microscopic in size. Common Nymphs addresses those challenges by including habitat and life history information regarding the nymphs, tips for their identification, and representative high-resolution photographs of more than thirty types of aquatic organisms and their imitations. In the seemingly saturated flyfishing literature, this book offers something truly groundbreaking. With state-of-the-art microscopy and their years of scientific and practical experience, Tzilkowski and Stauffer provide readers an innovative close-up look at identifying and imitating nymphs that have been historically underrepresented in the flyfishing and flytying literature.

Book Description
This lavishly illustrated guide will enable you to identify the caterpillars of nearly 700 butterflies and moths found east of the Mississippi. The more than 1,200 color photographs and two dozen line drawings include numerous exceptionally striking images. The giant silk moths, tiger moths, and many other species covered include forest pests, common garden guests, economically important species, and of course, the Mescal Worm and Mexican Jumping Bean caterpillars. Full-page species accounts cover almost 400 species, with up to six images per species including an image of the adult plus succinct text with information on distribution, seasonal activity, foodplants, and life history. These accounts are generously complemented with additional images of earlier instars, closely related species, noteworthy behaviors, and other intriguing aspects of caterpillar biology. Many caterpillars are illustrated here for the first time. Dozens of new foodplant records are presented and erroneous records are corrected. The book provides considerable information on the distribution, biology, and taxonomy of caterpillars beyond that available in other popular works on Eastern butterflies and moths. The introductory chapter covers caterpillar structure, life cycles, rearing, natural enemies, photography, and conservation. The section titled "Caterpillar Projects" will be of special interest to educators. Given the dearth of accessible guides on the identification and natural history of caterpillars, Caterpillars of Eastern North America is a must for entomologists and museum curators, forest managers, conservation biologists and others who seek a compact, easy-to-use guide to the caterpillars of this vast region. A compact guide to nearly 700 caterpillars east of the Mississippi, from forest pests to garden guests and economically important species 1,200 color photos and 24 line drawings enable easy identification Full-page species accounts with image of adult insect for almost 400 species, plus succinct text on distribution and other vital information Many caterpillars illustrated here for the first time Current information on distribution, biology, and taxonomy not found in other popular works A section geared toward educators, "Caterpillar Projects" An indispensable resource for all who seek an easy-to-use guide to the caterpillars of this vast region

Book Description
This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

Book Description
Includes a 72-minute DVD demonstrating basic nymph fishing techniques Color photo sequences to teach 11 different nymph fishing methods, including Czech, hinged leader, Leisenring lift, and wet-fly swing Detailed information on imitating mayflies, stoneflies, caddisflies, true flies, scuds, and sow bugs In nature nothing happens without a reason. The difficulty for the angler is merely that the reason is hidden some way beneath the surface.--G. E. M. Skues During the considerable periods of time trout spend feeding exclusively on underwater food forms, nymph fishing can be the most productive, if not the only way to catch fish. But understanding what occurs below the water's surface can be a challenge for even the most experienced angler. In Nymph-Fishing Rivers and Streams, aquatic entomologist and long-time fly fisherman Rick Hafele shares the information necessary to successfully decipher the mysteries of trout life. He starts by explaining their feeding patterns--where trout feed, when they feed, and what's available for them to eat. Sections on tackle and pattern selection help anglers sort through equipment and imitations to find the best outfit for their needs. The DVD complements the photos in the book that show various methods for nymph fishing. Also included is an angler's field guide to nymphs with details on their habitat, importance to trout, and the most effective patterns and fishing tactics to imitate them.
