This book is the third volume in the Handbook of Zoology series which treats the systematics and biology of Coleoptera. With approximately 350,000 described species, Coleoptera are by far the most species-rich order of insects and the largest group of animals of comparable geological age. This third Coleoptera volume completes the Morphology and Systematics volumes with 43 chapters and covers one of the largest radiations of beetles, the mainly plant-feeding Phytophaga, with information on world distribution, biology, morphology of all life stages (including anatomy), phylogeny and comments on taxonomy.
