How to tie it
Start the Sumo 50 denier thread and add tungsten at the thorax.
Tie in a bunch of pheasant tail barbs at the bend pointing rearward; these will later be pulled forward as the back, so leave them long.
Wrap the A8 Perdigon flat body thread forward to the 60% mark to form a smooth two-tone abdomen, then pull the pheasant barbs over the top and tie them down. The contrast between the flat thread underneath and the pheasant back is what makes this a bi-colour fly.
Dub a squirrel mask thorax over the tungsten, keeping it compact, and tie in partridge barbs each side as legs.
Pull the remaining pheasant barbs forward over the thorax as a wingcase, tie off and trim.
Whip finish and cement.
Tie it small for best results; at size 18-20 it takes trout, grayling and even whitefish.
