The Saturniidae are among the largest and showiest moths in North America. This comprehensive work covers the life history and taxonomy of a hundred species and subspecies of these Lepidoptera. The beautiful adults and larvae of all species are illustrated in thirty color plates, which are supported by line drawings of cocoons, distribution maps, and photographs of behavior. More than a natural history guide, this book includes chapters in population biology, life history strategies, disease and parasitoids, and the importance of silk moths of human culture. The systematic account emphasizes genetic differences among populations and the process of speciation and presents new information on experimental hybridization and life histories. For the student, researcher, and naturalist, here is practical information on collecting, rearing, and conducting original research. The entire text is referenced to an extensive bibliography.

Moths . . . has long been recognized as the most authoritative introduction to the moths of eastern North America. Intended for nonspecialists, but greatly appreciated by intermediate and advanced users, this book identifies and describes more than 1300 species in 59 families. The 1300 species, which include at least one in each of the 59 families present in the region, are those most likely to be encountered in eastern North America. Introductory chapters describe the anatomy and life cycle of moths and processes of collecting and preparing specimens. For each species, the book includes a description during the adult stage, the range as it was known in 1984, the flight season for adults, their relative abundance, and selected other information. Individual moths are portrayed from above, with wings extended, in 63 plates, many in color, while selected anatomical features, primarily wing shape and venation patterns, are illustrated in 76 black-and-white line drawings and photographs.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ... (6) Columns for Discount on Purchases and Discount on Notes on the same side of the Cash Book; (c) Columns for Discount on Sales and Cash Sales on the debit side of the Cash Book; (d) Departmental columns in the Sales Book and in the Purchase Book. Controlling Accounts.--The addition of special columns in books of original entry makes possible the keeping of Controlling Accounts. The most common examples of such accounts are Accounts Receivable account and Accounts Payable account. These summary accounts, respectively, displace individual customers' and creditors' accounts in the Ledger. The customers' accounts are then segregated in another book called the Sales Ledger or Customers' Ledger, while the creditors' accounts are kept in the Purchase or Creditors' Ledger. The original Ledger, now much reduced in size, is called the General Ledger. The Trial Balance now refers to the accounts in the General Ledger. It is evident that the task of taking a Trial Balance is greatly simplified because so many fewer accounts are involved. A Schedule of Accounts Receivable is then prepared, consisting of the balances found in the Sales Ledger, and its total must agree with the balance of the Accounts Receivable account shown in the Trial Balance. A similar Schedule of Accounts Payable, made up of all the balances in the Purchase Ledger, is prepared, and it must agree with the balance of the Accounts Payable account of the General Ledger." The Balance Sheet.--In the more elementary part of the text, the student learned how to prepare a Statement of Assets and Liabilities for the purpose of disclosing the net capital of an enterprise. In the present chapter he was shown how to prepare a similar statement, the Balance Sheet. For all practical...

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.
