Sulphur Dun Yellow

The Sulphur Dun is the Eastern equivalent to the Pale Morning Dun of the West. Sulphurs usually hatch in the evening, although they can hatch mid-day on cloudy days early in the season, with prolific numbers of mayflies hatching at a time. If this pattern doesn’t produce, trail a PMD Emerger  behind a dry fly.Available in size 14 to 20
