Welcome to the third edition of Daly and Doyen’s Introduction to Insect Biology and Diversity, by James B. Whitfield and Alexander H. Purcell, III. The textbook has been revised and updated to reflect the latest research in entomology, while retaining its balanced presentation of biological principles, insect identification keys, and the evolutionary perspective it brings to the study of insects. If you want coverage of biological principles as well as thorough and up-to-date insect identification keys in one affordable format—Daly and Doyen’s Introduction to Insect Biology and Diversity, third edition, is the text for you!
In keeping with the changing nature of the entomology course, the text has been revised with both entomology majors as well as other interested undergraduates in mind. This revision introduces key themes, such as evolution, applications to the real world, and new pedagogic tools, making the material even more relevant, interesting, and engaging. This third edition emphasizes biological principles more than previous editions and has been updated to present the latest information on genetics, development, physiology, evolution, phylogeny, and systematics, as well as provides a cutting-edge set of insect identification keys.
