It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity.

Separating 47 papers presented in the symposium as chapters, this book focuses on Chironomidae cytology and physiology; systematics and geographic distribution; and ecology, including aspects of lotic, lentic, and pollution biology.

This book is especially important for its potential use in water quality management.

This books contains information about their life cycle, feeding behaviour and their response to environmental factors. Chironomidae Larvae, Vol. 3: Orthocladiinae presents a wealth of information for scientific and practical purpose.

This book is an invaluable tool for aquatic ecologists and water quality management covering the most important tribes Chironomini and Pseudochironomini.
