This is a neat little nymph tied by Doug Korn. It is also know as a Glossossoma Larva. The material list is from Doug below. Doug mixes his own dubbing, so you can substitute his pink dubbing with something close to what you see here. If you want to mix your own dubbing then check out this link where Doug explains how he does it. Give it a go!
