One of the best cripple or emerging dun patterns out there and one of our Top 12 Blue Winged Olive flies.

This fly comes in a number of variations, from pale morning dun to larger drake imitations. The tail is sparse but sophisticated, with a combination of natural fibers and synthetics, imitating both a mayfly’s caudal filaments and the remainder of a trailing shuck. A goose biot body makes for a slender profile, and the combination of hackle and a CDC wing combines to replicate a dun whose wings have failed to entirely emerge. The result? An easy meal trout rarely turn down.
