The Virginia Save Our Streams biological monitoring method involves collecting and identifying aquatic macroinvertebrates, or stream insects and crustaceans. Different macroinvertebrates have different tolerances to pollution, so identifying the types of insects and crustaceans living under the water can determine water quality.
Most macroinvertebrate identification guides will ask you to look for distinguishing characteristics of the insect or crustacean. For example, how many legs does it have? Does it have antennae? Does it have gills on the abdomen?
Virginia Save Our Streams trains volunteers in macroinvertebrate identification through in-person workshops. In addition, the following resources may be helpful to volunteers.
VA SOS Identification Keys
Virginia Save Our Streams has several downloadable keys that are specific to the macroinvertebrates used in the VA SOS stream monitoring methods. Keys and further descriptions of the bugs are available on the Data Sheet Downloads page.

Field Guides
Field Guide to Aquatic Macroinvertebrates
This handy reference tool is designed to help volunteer monitors identify aquatic macroinvertebrates when conducting water quality surveys. The laminated brochure is convenient and durable for outdoor use. The diagrams of the macroinvertebrate larvae and adults are grouped by biological type and display common features that characterize each animal.
Symbols indicate the relative sensitivity categories (sensitive, less sensitive, and tolerant) based on the general Save Our Streams classification system. Most macroinvertebrates are identified to the order level for easy and accurate identification in the field.
