Synopsis
""How To Collect And Observe Insects"" is a comprehensive guide to the study of insects, written by Alpheus Spring Packard Jr. and originally published in 1863. The book provides detailed instructions on how to collect, preserve, and study insects, as well as information on their anatomy, behavior, and classification. The author covers a wide range of topics, including the use of nets and traps, the preparation of specimens for display, and the tools and equipment needed for insect observation. The book also includes numerous illustrations and descriptions of various insect species, making it a valuable resource for both amateur and professional entomologists. With its detailed instructions and wealth of information, ""How To Collect And Observe Insects"" remains a classic reference work in the field of entomology.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions, that are true to their original work.

Présentation de l'éditeur
In the Insects again, there are three modes of disposing the rings, and their appendages: 1. Where the number of segments is indefinite, and much like each other in form, supporting both thoracic and abdominal legs; as in the order of Myriapoda, 2. Where the head and thorax are closely united; and there are eight pairs of legs attached to the thorax alone, as in the A rachnida, 3. Where there are three distinct regions to the body; the head, thorax and abdomen, as in the I nseota. Moreover the true insects have three pairs of legs attached to the thorax; and are winged. The Myriapods grow by the addition of rings, after hatching from the egg; the Arachnids by frequent moultings of the skin; while the winged insects pass through a distinct metamorphosis. The young insect after being hatched from the egg is called the larva, from theL atin term meaning a mask, since it was the ancient belief that it concealed beneath its skin the form of the perfect insect. When full-fed, the pupa-skin rapidly forms beneath the tegument, and the insect in that form escapes through a slit in the back of the larva. The perfect insect is often called the imago. The larval state of insects which resembles worms, has also an analogous form to theM yriapods ;so spiders are analogous to Crustacea, while reminding us of the pupa state of the winged insects. Moreover, worms and Crustacea are, generally speaking, aquatic, breathing by gills, while insects are terrestrial and breathe by pores in the side of the body which communicates with a complex system of air tubes, including tubular blood vessels. The order of winged-insects is subdivided into seven divisions, occupying an intermediate rank between orders and families, and called by naturalists suborders. Of these theE ymenoptera seem to be highest in the scale, and theN europtera the lowest. Before characterizing these suborders, a

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
