Synopsis

""Directions For Collecting And Preserving Insects"" is a comprehensive guidebook written by Alpheus Spring Packard in 1873. The book provides detailed instructions on how to collect, handle, and preserve insects for scientific study, with a focus on the techniques and tools necessary for successful insect collection. The book includes information on the anatomy and classification of insects, as well as tips on how to identify different species. Additionally, Packard provides detailed instructions on how to construct and use various types of insect traps, including netting, pitfall traps, and light traps, as well as advice on how to properly store and display insect specimens. This book is an invaluable resource for entomologists, naturalists, and anyone interested in the study of insects and their behavior.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

A propos du livre

Présentation de l'éditeur

Insects differ sexually in that the female often appears tp have one abdominal ring less (one ring disappearing during the semi-pupa state, when the ovipositor is formed), and in being larger, fuller, and duller colored than the males, while the latter often differ in sculpture and ornamentation. In collecting, whenever the two sexes are found united they should be pinned upon the same pin, the male being placed highest. When we take one sex alone we may feel sure that the other is somewhere in the vicinity; perhaps while one is flying about so as to be easily captured the other is hidden under some leaf, or resting on the trunk of some tree near by, which must be examined and every bush in the vicinity vigorously beaten by the net. Many species rare in most places have a metropolis where they occur in great abundance. During seasons when his favorites are especially abundant, the collector should lay up a store against years of scarcity. At no time of the year need the entomologist rest from his labors. In the winter, under the bark of trees and in moss, he can find many species, or detect their eggs on trees, etc., which he can mark for observation in the spring when they hatch out. He need not relax his endeavors day or night. Mothing is night employment. Skunks and toads entomologize at night.

Présentation de l'éditeur

Leopold Classic Library is delighted to publish this classic book as part of our extensive collection. As part of our on-going commitment to delivering value to the reader, we have also provided you with a link to a website, where you may download a digital version of this work for free. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. Whilst the books in this collection have not been hand curated, an aim of our publishing program is to facilitate rapid access to this vast reservoir of literature. As a result of this book being first published many decades ago, it may have occasional imperfections. These imperfections may include poor picture quality, blurred or missing text. While some of these imperfections may have appeared in the original work, others may have resulted from the scanning process that has been applied. However, our view is that this is a significant literary work, which deserves to be brought back into print after many decades. While some publishers have applied optical character recognition (OCR), this approach has its own drawbacks, which include formatting errors, misspelt words, or the presence of inappropriate characters. Our philosophy has been guided by a desire to provide the reader with an experience that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic book, and that the occasional imperfection that it might contain will not detract from the experience.
