Field Guide to Aquatic Macroinvertebrates
- Item #: 631
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.
