This guide was developed by Kit Hastings and Susan Daniel to support the EPA Long-term Benthic Monitoring Project and Cooperative Science and Monitoring Initiative. It is intended to be used in conjunction with relevant identification keys, to aid in the identification of aquatic invertebrates found in the benthos of the Great Lakes. This project is still in development, but eventually all of the species found in the EPA benthos samples will be represented in this guide. Microscope photos of relevent distinctive features will be on each species page to aid in identification.
