Yellow Sally Dry Fly – Small Stonefly Pattern for Trout

A seasonal staple for late spring and summer when yellow stoneflies are active. The Yellow Sally presents a slim, bright profile that trout key in on during afternoon and evening activity, especially near banks and overhanging vegetation. When you see small yellow stoneflies fluttering over the water and trout rising along the edges, this is the fly you want on.

Yellow Sally hatches are one of the most underrated dry fly opportunities of the season. They don't get the attention that Green Drakes or Salmon Flies get, but they produce consistent, reliable surface action on rivers across the Mountain West and beyond.

When to Fish It

Late spring through mid-summer, typically afternoon and evening. Focus on the edges — shorelines, riffles near banks, and anywhere with overhanging vegetation. Yellow Sallies are small stoneflies, so they tend to concentrate along the margins rather than in the middle of the river. Fish it drag-free with a natural drift, and don't be afraid to give it a subtle twitch to imitate a struggling adult.
