The AIDGAP Freshwater Invertebrates Identification Guide is designed to help non-specialists identify the invertebrates found in pools, lakes, streams and rivers.
An identification key is included to enable users to identify macroscopic British freshwater animals to their major group and, where possible, to family, genus or species.
Designed for use with living specimens in the field, behavioural characters are given particular emphasis, but full morphological descriptions are also included. Characters which require considerable expertise or expensive equipment have been avoided.
