SBS CDC Sulphur Emerger/Dun/Stillborn- C&F Bobbin, Daiichi 1110, Sparkle Yarn, Turkey Biot Quill, Marc Petitjean Magic Tool & Select CDC

This is a simple but effective pattern where sulphurs (Ephemerella invaria) are prevalent and the trout are looking up. The colors and sizes can also be altered to represent other genus of mayflies, such as Ephemerella excrucians (pale morning duns) or Baetis tricaudatus (blue winged olive). This is a very productive pattern on the South Holston and Watauga tailraces in Tennessee.
