Tying Barr's Tung Teaser

Barr's Tung Teaser is an excellent all purpose nymph from John Barr. This pattern has become a staple in my box and the bins at the shop. We often fish it as the lead fly in a two fly nymph rig. This pattern combines the effective features of many popular nymphs- biot tails, epoxy back, hackle legs. Tie and fish in sizes 12-18.
