Additional Online Resources:

Macroinvertebrate Ecology (.pdf) is a 12-page .pdf document created for the Maryland State Envirothon. It provides a nice introduction to macroinvertebrate anatomy, life cycle, adaptations, and use in biomonitoring. There are other really good resources available from this website, including a nicely illustrated macroinvertebrate key. (Developed for Maryland - may not be adequate for all locations.)
Ecology Field Guide (.pdf - also available in Spanish) - This field guide was developed by Wolftree, Inc. of Portland, OR, to assist students and teachers in conducting outdoor ecological studies. Sections on "Aquatic Inverts", "Water Chemistry," and "Streamflow & Wetlands" are particularly useful to those studying water quality. Be sure to examine the "Ecology Concepts" and "Field Studies Intro," as well. The scope of the field guide extends well beyond the banks of a stream. Really good stuff!!
The Key to Macroinvertebrate Life in the River and Key to Life in the Pond are easy-to-use, single-page dichotomous keys developed by the University of Wisconsin - Extension and useful in identifying aquatic macroinvertebrates. You can download .pdf copies from the Water Action Volunteers Publications (scroll down to "riverkey.pdf")webpage. While you are at it, you may want to download a copy of Wonderful, Wacky, Water Critters. This 27-page booklet includes background information on the macroinvertebrates found in the river and pond keys.
West Virginia Department of Environmental Protection: Benthic Macroinvertebrate Resources webpage has many great resources and links. Under the "Various Guides and Identification Keys" section, check out the Macro-ID guide (pdf). Under the "Additional Information" section, check out the Identification Activity (html).
Cacapon Institute: The Potomac Highland Watershed School e-school. In particular, check the Benthic Macroinvertebrate Portal for activities such as "Introduction to Stream Sampling" and "A Virtual Stream Sampler."
Maryland Department of Natural Resources Maryland Stream Waders web page provides some basic information about the state's monitoring program. Of special interest might be the Family-level Key to Stream Invertebrates of Maryland and Surrounding Areas. The key is a downloadable 1.5 MB .pdf file.
"Aquatic Insect Fact Sheets" - Downloadable .pdf files from Creek Connections. The "fact sheets" are nicely illustrated and informative. Creek Connections was developed at Allegheny College as a partnership with regional K-12 schools in Northwest Pennsylvania, Southwest New York, and the Pittsburgh. They emphasize hands-on, inquiry-based investigation of local waterways. Lots of information - great stuff!!
The Hoosier Riverwatch Training Manual contains a useful section on biological monitoring and macroinvertebrates. In particular, Chapter 5 includes information on macroinvertebrate identification and a taxonomic key. Hoosier Riverwatch is sponsored by the Indiana Department of Natural Resources - Division of Fish and Wildlife.
Macroinvertebrate Field Identification Cards - The Connecticut Department of Energy & Envrionmental Protection has developed a program called: Rapid Bioassessment in Wadeable Streams & Rivers by Volunteer Monitors (RBV). The Field Identification Cards and other resources for water quality monitoring could provide useful information for macro ID and student research on specific macros.
Stroud Water Research Center - Leaf Pack Network; Leaf Pack Experiment Kit (LaMotte Company) includes the sorting sheets I use in class and at workshops; there are a number of other resources on this site, including a Macroinvertebrate Gallery (Schulylkill River Project)

SalmonWeb [unfortunately, the website is no longer active; it's frequently referenced by other sites using the B-IBI protocol] - this community-based monitoring program was developed to promote "... the use of biological monitoring to understand the health of stream systems ...." The site contains information on the Benthic Index of Biological Integrity (B-IBI) for the Puget Sound Lowlands and a number of useful links.

See other programs using B-IBI below:

Puget Sound Stream Benthos - describes the B-IBI and provides examples of its application; GIS map of WA State shows sites tested and B-IBI scores

Streamkeeper (Adopt-a-Stream Foundation) video link - "Fresh Waters Flowing" and "Biological Monitoringl Protocol" are two YouTube videos featuring Dr. James Karr and Charley Dewberry. They discuss the influence of human activity on stream health and a method for determining the level of disturbance using stream organisms.

Also, check out the "Aquatic Bug Monitoring" links for information on water and bug monitoring, how to collect bugs in moving water and ponds, and a pictoral guide to common orders of macros.
Society for Freshwater Science - This site contains information about SFS and its activities. The Education and Outreach section of this site contains an Image Library of aquatic organism that could be of interest.

The Stream Bugs as Biomonitors: Guide to Pacific Northwest Macroinvertebrate Monitoring and Identification includes a CD-ROM (PC-compatible only) and field guide. The website also provides information and a scaled-down version of the guide.
