The fourth edition of this excellent identification guide to aquatic insects in New Zealand has been updated with the latest information, making it an essential resource as the demand for river surveys and water quality studies continues to grow. Since the third edition was published five years ago, there have been great advances in our knowledge of New Zealand's aquatic insects. This edition includes information from several new publications about the systematics of New Zealand aquatic insects. More than 80 new titles have been added to the reference list and cited in the text; this serves both to document taxonomic changes and to guide the reader to the expanding literature on the aquatic insects of NZ. The book provides keys to enable insects to be identified to the family or genus level. Notes on distribution, habitat, and problems likely to be encountered with identification are included, along with full references, glossary of terms, and an index of taxa, common names, and general subjects. This is a joint publication venture of the Entomological Society of New Zealand (Inc.) and the New Zealand Freshwater Sciences Society.

This book recounts the habits of many interesting and unusual exceptions to the rule that insects are typically terrestrial forms of life. It examines the different ways that groups of species have developed modes of existence in or on the surface of water, and gives reasons why the gross morphology of insects is not favorable for life in or near bodies of water, such as wings that fail to function after coming into contact with water, rendering them useless.

Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations.
