About the Pale Morning Dun Trout Flies Fly

The Pale Morning Duns are prevalent on most western US rivers from July into September. I normally fish the Henry's Fork in early August, and at that time one can count on a PMD spinner fall beginning mid-morning on most days, followed by or concurrent with an emergence of duns lasting well into the afternoon. The emerger and the spinner have proven to be the two most consistently effective designs of fly in this area. I've found the dun design effective only during dense hatches of the PMDs.

Expert Tip:

I've been Fly Fishing for about 45 years and tying flies for approximately 30 years. My early fly fishing education was on the insect-rich rivers of the Catskill Mountains in New York State, the Beaverkill, Willowemoc, Esopus and the branches of the Delaware. Since then, I've fished for trout in most of the "trout" states in the US, as well as in Canada and northern Europe. My favourite water is the placid meandering stretch of the Henry's Fork of the Snake River near Last Chance, Idaho, where it passes through the Harriman Ranch and where the rainbows are wild, well-fed and very selective.
