The Pale Morning Dun (PMD) is one of the most dependable mayfly hatches on Western trout rivers. This extended-body version presents a slimmer, more realistic silhouette that sits low and clean on the surface.
At #18 it matches the smaller end of PMD hatches. Fish it on a dead drift to rising trout during midday emergences.
Present it upstream on a drag-free drift through the feeding lanes, and keep an eye on the inside seams and tailouts where duns and spinners collect.
