Fly patterns imitating the molting stage can have different shapes but they need to have the following parts, trailing shuck, old (aft) body part, and new (fore) emerging body part. Newly molted insects also usually have a light coloration. My most successful patterns are Hare’s Ear Molt Nymph , Molt Scud and Bead Head Molt Nymph.
