The Barr’s Emerger is high on many anglers list of favorite flies. A simple concoction of feathers and dubbing, this simple pattern is an all around great fly. The idea behind this pattern, according to John Barr, was to imitate the adult insect creeping out of the nymphal shuck. The wet BWO version is the most popular variation, and the one Mel will be teaching at this month’s Fly Tying Class.
