Book Description
INSECTS PROVIDE an ideal medium in which to study all the problems of physiology. But if this medium is to be used to the best advantage, the principles and peculiarities of the insect's organization must be first appreciated. It is the purpose of this book to set forth these principles so far as they are understood at the present day. There exist already many excellent text-books of general ento mology; notably those of Imms, Weber, and Snodgrass, to mention only the more recent. But these authors have necessarily been preoccupied chiefly with describing the diversity of form among insects; discussions on function being correspondingly condensed. In the present work the emphasis is reversed. Struc ture is described only to an extent sufficient to make the physiological argument intelligible. Every anatomical peculiarity, every ecological specialization, has indeed its physiological counterpart. In that sense, anatomy, physiology and ecology are not separable. But regarded from the standpoint from which the present work is written, the endless modifications that are met with among insects are but illustrations of the general principles of their physiology, which it is the aim of this book to set forth. Completeness in such a work is not possible, or desirable; but an endeavour has been made to illustrate each physiological characteristic by a few concrete examples, and to include sufficient references to guide the student to the more important sources. The physiology of insects is to some the handmaid of Economic Entomology.

Book Description
Insects live alongside us in great profusion – sometimes even in intimate proximity. Their importance to the ecosystems of our world, and to our own survival, cannot be overstated. But it can be challenging to relate to them as fellow living beings when their bodies' structure and function are so dramatically different from our own. This excellent RSPB guide to insect anatomy aims to demystify the way that insects live, from the fine detail of their internal processes to the way they co-exist with all other forms of life. Insects exhibit dizzying diversity across their millions of species. Among them are mighty hunters, voracious plant defoliators, deep divers, high-fliers, master builders and devoted parents. Within the vast nests of honey-bees, ants and termites, we see them come together to form a huge, complex, multifaceted living machine. All this variation and potential has come about through evolved modification of a simple but perfectly elegant body plan. Each chapter of this book tackles a particular body system or aspect of insect biology, from respiration to digestion, movement to metamorphosis. Using a step-by-step approach, the book breaks down structures and processes and explores the myriad ways these are expressed in different insect groups. Separate pages delve into particular aspects of insect biology and ecology, such as how their colours are formed and the biology behind their remarkable migratory behaviour. Featuring numerous diagrams and more than 200 colour photos, this user-friendly guide is perfect for anyone interested in learning more about these extraordinary animals that – in terms of numbers, if not size – dominate our planet today.
