This book brings together knowledge of the diverse relations of insects to their environment through the medium of their food, discusses the devious ways in which they have exploited the living world in their search for food, and shows how these activities have guided their evolution and affected that of many other animals and plants.
The matters presented in this book had not previously been dealt with as a whole in any single work. The generalized treatment of the subject matter has made it possible to include sufficient detail to relate the food habits of insects to those of other animals and to discuss their bearing on many general biological problems. The classified bibliographic references relating to food habits have not been collated elsewhere. They will enable the reader to find much additional material on the matters discussed, and to follow in detail any particular subject on which he may wish for complete information.
