The development of specialised feeding habits during the course of time by human beings is paralleled in the majority of animals, in particular have developed special peculiarities, and insect larvae which in most cases are quite characteristic of the species concerned. This applies especially to phytophagous insect larvae, and anyone with the requisite experience can say with a fair degree of certainty which insect larva is responsible for any damage to be found on a plant. It leaves behind a definite "feeding pattern" which might be compared to a "visiting card" on which the genus and species are marked in runic characters. Whoever has learned to read the runes can readily determine who has been feeding on the affected spot, solely on the basic of the "visiting card" left behind. From the known factors - the name of the plant and the type of feeding patter- and after some study of the various types of plant infestation, both the genus and species of the larva producing the feeding pattern can be worked out without difficulty. The importance of "feeding pattern investigation" has now far outstripped the successes to be obtained by normal collecting. Previously, when wishing to list the species of insects present in any given locality they were caught with the net, by sugaring and other methods. This always resulted in a very defective "list" of the insects in fact existing in the locality concerned.

The first-ever reference to the sign left by insects and other North American invertebrates includes descriptions and almost 1,000 color photos of tracks, egg cases, nests, feeding signs, galls, webs, burrows, and signs of predation. Identification is made to the family level, sometimes to the genus or species. It's an invaluable guide for wildlife professionals, naturalists, students, and insect specialists.

This book brings together a wide range of sampling methods for investigating different arthropod groups. Each chapter is organized to describe and evaluate the main sampling methods (field methods, materials and supplies, sampling protocols, effort needed, and limitations); in addition, some chapters describe the specimen preparation and conservation, species identification, data collection and management (treatment, statistical analysis, interpretation), and ecological/conservation implications of arthropod communities. The book aims to be a reference for zoologists, entomologists, arachnologists, ecologists, students, researchers, and for those interested in arthropod science and biodiversity. We hope the book will contribute to advance knowledge on field assessments and conservation strategies. Arthropods represent the most speciose group of organisms on Earth, with a remarkable number of species and interactions still to be described. These invertebrates are recognized for playing key ecological roles in terrestrial, freshwater and marine ecosystems. Because of the increasing and relentless threats arthropods are facing lately due to a multitude of human induced drivers, this book represents an important contribution to assess their biodiversity and role in ecosystem functioning and generation of ecosystem services worldwide.
