Insects feed on a wide range of organic materials. About 75% of all species are phytophagous, and these form an important link in the transfer of energy from primary producers to second-order consumers. Others are carnivorous, omnivorous, or parasitic on other animals. In accord with the diversity of feeding habits, the means by which insects locate their food, the structure and physiology of their digestive system, and their metabolism are highly varied.

The feeding habits of insects take on special significance for humans, on the one hand, because of the enormous damage that feeding insects do to our food, clothing, and health, and, on the other, because of the massive benefits that insects provide as plant pollinators during their search for food (see also Chapter 24). In addition, because many species are easily and cheaply mass-cultured in the laboratory, they have been used widely in research on digestion and absorption, as well as in the elucidation of basic biochemical pathways, the role of specific nutrients, and other aspects of animal metabolism.
