This simple yet effective mayfly nymph pattern really kicked butt this past year in several Bc lakes that we fished. It uses Ed Smith's new Micro sized Liquid Lace.
I used 3 frongs from a wood duck feather for the tail Tan Thread, A size 14 mustad#80050BR curved nymph hook and a tan Pantone marker. The Thorax is tan Seal dubbing with stretch-flex over it for a wing case. 12# mono eyes; color in black pupils.
And then hold on to the Rod!
