Aquatic Macroinvertebrates in Motion Videos

Explore our video library of aquatic macroinvertebrates wriggling, swimming, and crawling through stream water! Collected during a stream study with materials from the Leaf Pack Network®, many of these critters may be found in streams and ponds near you.

Use these videos to help confirm your identifications or simply to appreciate the cool way the macroinvertebrates move! If you prefer, you can watch the playlist on YouTube.

There is also a quiz version of the video library if you would like to test your or your students’ macroinvertebrate identification skills.
