If Blue-Winged Olives are hatching and trout are eating them off the surface, we'd highly recommend this classic from West Yellowstone. Sparse, but visible, the Sparkle Dun is a stellar dry fly that is sure to induce an eat. The tail on this fly does an excellent job imitating the empty nymphal husk that can often be found still attached to an emerging dun and this can trigger eats from even the most selective of trout. It's a pretty simple tie and one that allows you to fill your fly box quickly for your next trip to the river.
