Thread To match the body (yellow used here) 70 denier (8/0)
Materials
Chenille (butt/egg sac) Red, green or yellow chenille (Small, 2 wraps)
Floss (body) Gold, yellow, purple, brown or orange floss (8 inches)
Woodchuck tail (wing) Natural deer hair (Medium tuft, stacked (squirrel, groundhog or badger also work))
Dry fly hackle Grizzly or brown, or both (1 feather)
How to tie it
Lay a thread base in a color matching the body down to the bend. There is no tail on this fly.
Butt: strip the core of a piece of small chenille and tie it in at the bend with loose wraps to minimize the bump, then take the thread back to the tie-in point.
Take three open wraps of thread forward to give yourself room, wrap the chenille two full turns for a short pronounced butt, back the thread off and catch the chenille where the thread hangs. Trim. A little shagginess here is fine and can be cleaned up later.
Take the thread forward to a couple of eye-lengths behind the eye and tie in the floss there, then wrap it all the way down to the butt and back up for at least two layers. Matching thread color means you do not have to build it thick. Tie off and trim.
Trim up the chenille butt so it is neat.
Wing: stack a medium tuft of woodchuck tail, spin the thread clockwise to cord it up for a tighter bite, and tie the wing in on top. Not lying too flat. Take one or two wraps underneath the wing to prop it up.
Trim the butt ends off close in front and add a few extra thread wraps to smooth the area for the hackle.
Tie in the grizzly (or brown, or one of each) hackle and take four or five turns forward, stopping before you crowd the eye.
Push everything back, take a few wraps rearward to make room, whip finish and snip or singe any fibers pointing forward. Add head cement.
