Aquatic macroinvertebrates are biota large enough to see without a magnifier (for example Mayflies, snails and crayfish.) They are an important part of stream ecosystems for scientists, naturalists and folks who like nature. Here we’ll discover why they are important by seeing them up close, through microscopes alongside the historic Oregon Branch in Cockeysville, MD. We’ll catch them, see their homes up close and learn about how they can tell us a story about their stream’s health.
