YFG Flies Doc’s Mayfly Nymph
With fluffy gills and a bead head for weight, Doc’s Mayfly Nymph from Yellowstone Fly Goods is the perfect small mayfly to try when little BWOs 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.

Great detail on the gills and realistic movement. I used it during a morning hatch and saw several trout take it under a foam dry. It’s a solid choice for small mayfly imitations.
Dan Ferguson –
The weight from the bead head keeps it in the right spot. It worked well in slow-moving water where fish were feeding just below the surface. A bit small for larger trout, but perfect for smaller ones.
Tracey Davidson –
Felt natural in the water. The gills fluttered well and fish reacted immediately. I’ve used it in multiple streams and it’s one of my go-to nymphs for mayfly emergence.
