The famous Hare’s Ear pattern has been around forever.  Lots of people have fished with it and caught fish on it.  As any fly tyer knows, it’s entertaining to try new materials, different colors of dubbing, or anything new that comes into the market.  The Two-toned Surveyor came about after we had heard about the surveyor nymph, which is tied with a light color of rainbow dubbing for the abdomen and thorax.  We fished with it, and had some good luck with it.  After having found a darker shade of rainbow dubbing, we tried it out and tied this varition.  In my opinion, it has been more effective than the surveyor, and has been very effective on the lower Provo River this spring.  It has become a must in any fly box.  Tie some of these up in different sizes and give them a try on your favorite trout steam.
