This bug is actually really easy to tie. You just cut a 4mm or 6 mm piece of closed cell foam.(Rainy's is open cell foam, but will sink eventually) Cut the tail piece of the foam at an angle. Then cut a slit down the middle of the foam. Attach the Foam to your hook at the neck of the fly, Then Superglue the hook shank and push the foam down onto it. Tie in your Crystal Flash, Your Wing The Legs then the dubbing and your done. The secret to the under wing is using transparent scotch tape on the back of your Hen Feather. Then just use a marker for the eyes and the body.
