This pattern is a variation of the classic Pheasant Tail Nymph. It’s body, tail and rib are the same as the original, but the thorax of this pattern includes a few strands of pearl Lurex laid over the peacock herl.

Pearl Lurex gives a wonderful flash and sparkle to any fly, and it the case of the Flashback Pheasant Tail Nymph only a small amount of the material is used to keep the effect as subtle as possible. The aim is to suggest the sparkle caused by gases trapped under the skin of a mature nymph as it rises to the surface to transform into the winged dun.

This pattern is highly effective on both rivers and lakes, especially during a hatch of small- to medium-sized dark mayflies.
