Aquatic insects: voracious predators, architects, and environmental indicators. Join Cornell University Naturalist Outreach students for an introduction to the diverse aquatic insects, and their importance in food webs. This is one of many 'naturalistoutreach' science videos on YouTube that explore nature and biodiversity. See http://blogs.cornell.edu/naturalistou... and NYS 4H Stem pages for guides and worksheets on aquatic insects, stream ecology, and other topics. This video is a coproduction of Dr. Linda Rayor, the Ithaca College Park Media Lab, and NYS 4H.
