This fly is my bread and butter on the Snake River in eastern Washington. I also tie it in purple and fish both often for summer run fish.
Hook: Tiemco 7999 or similar in size 4 or 6
Thread: Black 6/0 Danville
Tag: Butt of flame red floss
Body: Black sparkle chenille
Hackle: Black dry fly hackle palmered over the chenille
Collar: Two turns of natural guinea
(For the purple version, replace the thread, chenille and hackle with purple.)
