Learn from the classic text in entomology! Introduction to the Study of Insects has been the standard text for introductory entomology since it was first published in the 1950s by the late Donald Joyce Borror and Dwight Moore DeLong. In this new Seventh Edition, Triplehorn and Johnson combine the taxonomic approach of this text's definitive study of insects with thoroughly updated coverage of insect biology and evolution as well as insect phylogeny. Through the text's focus on issues of insect systematics and evolution, you'll learn to appreciate the magnitude of the diversity of insect life as well as the immediate and long-term threats to insect diversity. The thorough insect identification keys and extensive accompanying illustrations make the book an invaluable reference for identification of all of the families of insects found in the continental United States and Canada. Triplehorn and Johnson also provide you with information on up-to-date insect collection methods, such as the use of the Global Positioning System. - Back cover.
