Tie in tail. Tie in 2-3 pheasant tail fibers at wrap up to 1/3 point. Tie in partridge feather by tip. Dub thorax. Take 11/2 -2 turns of partridge to form soft hackle collar. Form head with thread. Whip and tie off.
Mayfly emerger imitation for Sulphur (Ephemerella dorothea) in Eastern waters, and PMDs or Pale Morning Duns (Ephemerella infrequens) out West.
Great looking soft hackle! Sulfur is a pattern that works here in NEPA almost all season long (same with a cream cahill or cream elk hair caddis). Reminds me that I've got to get some more tied up for next Spring.
