You’ll often find BWOs on the greyest of days, so ’tis fitting that this ancient-and-tradtional Olive pattern sports the same somber hues. It also makes a fine Early Grey Stone.
Hook: Dry or wet fly, 14-18
Body: Silk dubbed with water rat (muskrat) or mole fur
Hackle: Waterhen under covert feather
Tying Notes: Waterhen is difficult to track down. Starling or blue-grey dun hen are suitable replacements. You should be able to see the thread clearly through the dubbing — I call it “dusting the thread.” This fellow is slightly on the heavy side of dubbing. Keep enough thread waxed (I used cobbler’s wax) to avoid having a bright yellow head. You can find a general North Country spider video tutorial here.
