Field Guide to Benthic Macroinvertebrates

This photographic guide is an attempt to assist students and researchers in the field to identify some common freshwater benthic invertebrates. It is a guide to the juveniles (larvae or nymphs) and includes only a few adults. It is not a comprehensive guide to all the animals you might collect. Because of the difficulty of identifying freshwater invertebrates in the freshwater I expect that this will become an essential field tool for students and researchers. Detailed taxonomic identifications of fauna will require more comprehensive sample collection protocols and identification keys which are beyond this publication.
