The sheer number of species and, especially their astonishingly diverse characteristics and way of life, pose endless questions and opportunities for research. Herbivorous insects are the very epitome of such diversity, and among them, the Chrysomelidae, embracing 40 000 described and even more undescribed species, are among the most bounteous adaptive radiations in the animal kingdom. The many and varied topics dealt with in this book cover almost all aspects of phylogeny, classification, paleontology, parasitology, biogeography, defenses, population biology, genetics and biological control, as well as many other subjects. The most renowned specialists in all these fields have been chosen to put together a diverse, state-of-art publication, which summarizes all that is actually known about these beetles.
