This past winter I was fortunate to attend a fly-tying session led by James ‘Jim’ Krul. Jim is the former Director of the Catskill Fly Fishing museum. He’s also contributed to a number of Fly Fishing & Tying magazines and publications. He provided a wealth of information on how to tie and fish this fly. I was very interested because I use Stimulators for my ‘Dry/Dropper’ rigs. This Foam version is extremely easy to see in the water and has better floatability than the traditional floss bodied Stimulators. It is also different in that it uses Badger for the tail and wing. If you don’t have badger, just substitute Elk/Deer Hair for the tail and wing.
To tie this fly, start your thread behind the eye. Make securing wraps and cut off the butt end. Cover the hook shank with thread, ending your thread even with the hook point. You are now going to tie in your tail. Take a small bunch of Badger, stack it if you so desire, and tie it in. It should extend approximately a hook gap length beyond the bend of the hook.
At the tie in point of your tail, tie in your body Hackle. It should be a hook size or two smaller than the hook you’re tying on. Next, tie in a prepared strip of Orange 2mm foam. You can cut a narrow strip of foam with your scissors, or if your tying multiple flies, use a paper cutter to cut foam strips 2 mm in width. Bring your thread just beyond the halfway point of your hook shank. Wrap your Foam strip forward (You want just enough tension when wrapping to form a smooth body) and tie it off with your thread. Cut off the butt end. With segmented wraps, palmer your Hackle forward and tie it off with your thread. Cut off the butt end. This completes the first segment/body of your fly.
Next, tie in your Badger (or Elk/Deer hair) wing. It should be a little thicker than your tail and extend halfway down the Tail of the fly. Once secured, trim off the butt ends and with your thread, lay down a smooth base for the rest of the fly. Bring your thread back to the wing tie in point. Tie in an additional Grizzley Hackle. You can size it to the hook, or when I’m tying this fly, and my hackle feather is long enough, I use the excess body hackle for my Thorax. After tying in your Hackle, tie in a prepared strip of Yellow Foam. Again, it should be approximately 2 mm in width. Wrap it forward and tie it off behind the eye. Cut off the butt end. Now wrap your Hackle forward and tie it off behind the eye. Whip finish your fly and apply a drop of Head Cement if you so desire.
