It is immediately evident that the Prince Nymph is only distinguished from the Pauper Nymph by virtue of one identifying characteristic..the biot tail. Everything else is identical. I believe, from personal experience limited to two seasons that the Pauper fishes every bit as well as the Prince Nymph on streams. It makes a great Caddis pattern, the peacock and white biot being the primary exciters. In lakes, the tail may make a difference if you present it during a mayfly emergence. I don’t believe it adequately represents a mayfly. But, there is no discounting its success. I think from a practical tying point of view and because I hate tying in biot tails (not the wings), it is easier to teach someone to tie The Pauper. Tie up some of these and give them a try without and with a bead. Biots, as you probably know, come in a variety of colors. Try different colors for the biot wing.
