Hellgramite and Stonefly Video

This video takes a look at some Hellgramite Larva and Stonefly Nymphs (the real thing!). These are two of the largest nymph and larva insects that occur in Ontario rivers that are important to fly fishing. Stonefly nymphs cling to the undersides of rocks. Once they have matured as a nymph, stoneflies will crawl up onto the tops of rocks, above the surface of the water and transform into Large flying stoneflies. Hellgramites are quite a bit larger, and have a much different way of transforming from an aquatic insect into an flying insect.
