YFG Flies Doc’s PMD Mayfly Nymph
With fluffy gills and a bead head for weight, Doc’s PMD Nymph from Yellowstone Fly Goods is the perfect small mayfly to try when little Pale Morning Duns are popping off but the fish are feeding sub surface. The small bead head adds just the right amount of weight to position this fly within the top of the water column where emerging mayflies struggle to reach the surface. Fish this as an emerger under a foam dry to great effect.

This fly mimics the PMD mayfly perfectly. The gills are soft and realistic, and the bead head keeps it down where it should be. I’ve used it during early morning when fish are active and it’s been very effective.

Great detail on the gills and the weight helps it stay in the right spot. Works well as an emerger under a dry fly. A solid choice for mayfly season.

Fished it in a coldwater stream and saw several trout take it. The small size and realistic movement made it stand out. Would recommend to any fly fisher targeting emerging mayflies.
