Sulphur Dun Dry Fly
One of the most prolific hatches, the sulphurs are a late May early June season pleasure. Make sure to take a handful of the dry flies to the river for the late afternoon hatch. Sulphur male duns have larger eyes and are darker in color, while the females are generally lighter and more of a pale yellow. The spinner falls occur at dusk with the females dropping their eggs into the water from above in the air.
