Arctopsyche grandis (Great Gray Spotted Sedge) Caddisfly LarvaArctopsyche grandis (Great Gray Spotted Sedge) Caddisfly Larva View 14 PicturesAt first I had trouble believing this giant Hydropsychidae larva was actually a member of its family, because of the size. I had never seen such a thing. It turned out to be a member of this exceptionally large species with a fitting name, grandis.
