The League’s Save Our Streams program uses aquatic macroinvertebrates – insects and crustaceans that live on the bottoms of rivers and streams – to help measure water quality. However, those tiny legs and tails can be challenging to ID for beginning water quality monitors. We’re here to help!
Now you can become a “macro pro” from the comfort of your desk chair. Our new macroinvertebrate ID videos include photos and illustrations, key identifying features, and interesting tidbits about each critter. Visit the League’s YouTube channel. Look for “Macroinvertebrate ID: Save Our Streams” to get started, but feel free to check out all our other stream monitoring videos. Happy critter hunting!
