PHWFF: Nov 9, 2016 – Harry’s BWO Dry Fly

“Harrys BWO” tied by Nicole March

Our November 9th PHWFF New City, New York meeting was lead by Harry who took over our Fly Tying for the evening and taught our participants his BWO Dry Fly. This step-by-step I have put together to help aide in those who are tying at home after meetings, It may be little different from what you were taught that night.

I have done my best to tie this in Harry’s style and all instructions will be word for word from his pattern, (with a few of my comments) to help match up with what you took in that evening, in way of his techniques.

Just keep in mind that even though I am tying this fly based on his instructions in the way he taught you that night; all individual tyers have different techniques.

Me and Harry teach our dry fly techniques different and have different styles, which is why every few months when we switch who teaches the pattern for the evening, you are actually expanding your knowledge. Its great to learn from different tyers!

So here we go!

Gather your materials!

Harrys BWO

Blue Wing Olive Materials List
Hook: Dry Fly Hook Size 18
Thread: Olive Uni-Thread Size 8/0
Hackle: Blue Dun Dry-Fly Hackle (Size 18)
Tail: Blue Dun Dry-Fly Hackle Fibers
Body: Olive Super Fine Dubbing
Wings: Blue Dun Dry-Fly Hackle Tips


Attach the thread to the hook shank at the 3/4 mark on the shank.

Now run your thread down toward the hook bend and stop it across from the barb (or barbless in this case)

Select and align the tips of 12-15 blue dun dry-fly hackle fibers. Tie these fibers onto the hook shank at the point above the barb. They should be about one-and-a-half times the length of the hook gap.

Once tied in with a loose wrap, dont be afraid to grab those waste ends and use them to re-position the tail fibers. As you can see above, after tying it in I had some that slipped and are shorter than others, but by manipulating those waste ends I fixed that problem for the next step.

Trim and cover the waste ends
Select and align two blue dun dry-fly hackle tips so that they flare away from one another when held back to back. The wings, when finished, should be approximately the length of the hook shank.
Strip all the hackle barbs off of the feathers leaving just the tips. Tie these tips down to the hook extending over the hook eye at the 3/4 mark on the shank.
Stand the wings upright and place several thread wraps in front of the base to keep them in place.
Advance the thread back to the rear end of the shank.
Pinch dub your thread (dubbing noodle) very lightly with the super fine dubbing
Build a small tapered body up the hook shank.
Stopping just behind the wings.
Strip the bottom section from a blue dun dry-fly hackle, leaving the stalk exposed, and tie this just behind the wings.
Bring your thread to the front of the wings, covering and cutting the waste ends then stopping a little behind the eye and get ready to wrap the hackle!
Advance the blue dun dry-fly hackle up the body of the fly, taking four to five turns of hackle behind the wings and three turns in front of the wings.


Build a small neat head for the fly, whip finish the thread and cement.

Thats it! Nice Work! Now remember, this pattern may be a little different than what you were taught that night since our styles differ so please ask any questions you need! I will be glad to clear up any differences! Happy Tying and I will see everyone in class at the next meeting.
