Best match for the hatch.
"I have a river with a big yellow Sally hatch and this fly works the best for me. I have tried other, but this performs the best."
Yellow Sally stonefly nymphs are available much of the year, but more active during warm summer months. RIO's My Gal Sal is the perfect imitation of this natural, with a pale golden yellow belly covered by a dark brown and copper back tied on a barbless Gamakatsu hook with a tungsten bead.
The following are the bead sizes per hook:
Size 14 - 3.3 mm
Size 16 - 2.8 mm
This pattern is available for U.S. shipping only.
