Despite its pervasive nature opinions differ as to what predation really is. So far it has been defined only in negative terms; it is thought not to be par asitism, the other great process by which one organism harms another, nor filter-feeding, carrion-eating, or browsing. Accordingly, one could define predation as a process by which an animal spends some effort to locate a live prey and, in addition, spends another effort to mutilate or kill it. Ac cording to this usage of the word a nudibranch, for example, that feeds on hydroids would be a predator inasmuch as it needs some time to locate col onies of its prey which, after being located, scarcely demand more than eating, which differs little from browsing. From the definition just proposed consumption of the prey following its capture has been intentionally omit ted. Indeed, an animal may be disposed of without being eaten. Hence the biological significance of predation may be more than to maintain nutrition al homeostasis. In fact, predation may have something in common with the more direct forms of competition, a facet that will be only cursorily touched upon in this book.

Despite this, however, there is at present only a limited understanding of the constraints on foraging patterns of caterpillars. A major problem is the difficulty of designing and analyzing experiments which account for multiple constraints. Caterpillars: Ecological and Evolutionary Constraints on Foraging reviews the present state of research into caterpillar biology while arguing for a multiple factor approach in studying insect herbivores. Written by leading authorities in entomology and ecology, it provides an explicit framework for carrying out such investigations. The book details the constraints of the foraging patterns of caterpillars, including phylogenetic constraints, the physical environment, nutritional supply and demand, predators, and plant chemical defenses. It also analyzes caterpillar adaptations, such as sociality, mutualism, aposematism, and cryptic morphology, and covers population dynamics and the influence of environmental factors upon tropical, temperate, and arctic caterpillars. The book concludes with a discussion of the implications of this material for pest management, forest systems, and agroecosystems.
