The Anato-May series of nymphs is a cool collection of patterns from Ken Morrish. We can only assume the name comes from the fact that the patterns are so anatomically correct with three tails, six legs, etc. They also feature a small bead head that doesn't stray away from the mayfly silhouette and is a neutral black color. The Hare's Ear is a good all-purpose color for many mayfly species. Size 14 pictured.
