You bet that fly catches BIG fish. try the slow retrieve. the reason the tail is tied somewhat at a downward angle is because it acts like a beavers tail and actually flaps when you retrieve it. This fly is awesome in Whidbey Island Area lakes as well as BC !
The color is slightly off in this shot but, Damsels can be tyed in a variety of colors including this one.
Start w/a Mustad 80050BR or Tiemco 200R (this one is on a #10). Tye in your Marabou tail. be sure not to leave it too bulky at the tye in point because you're going to want a slender body that has a nice taper towards the thorax.
Next tye in your (oil-filled) Liquid Lace on top of the hook useing 4 overlapping wraps 1/6th " behind the hook eye.
While streching the lace towards the tail, sparsely wrap it with your olive thread. When you arrive at the tye-in point of the tail REALLY strech the lace and give it 4 good overlapping wraps to trap the oil.
Taking a Pantone Olive Green Pen (in this case) color the front portion of the under body (thread/feather/Liquid Lace to create a slightly darker thorax area.
Strech the Lace Tight (til wont strech no more) and make 2 wraps at the tail tie-in point as you start wrapping the Liquid Lace Towards the fron of the hook release all tension and let the lace wrap on the hook createing a perfectly segmented body.You will also notice that the Lace/ Fly body will have a natural taper to it. This is due to the hydraulics of this product and the pressure building inside the tubing.
Approx. 1/4" behind the eye of the hook,finish your Liquid Lace by taking 4 overlapping wraps with your thread.This locks in the oil and gives the fly that translucent look to it.
Tye in a piece of scud back or strech-flex that will be slightly darker than your body where you tyed off your lace.
Next tye in a small set of eyes directly behind the eye of the hook. In this case I used Burnt Monofiliment (20# Green).
Next, I use seal fur dubbing and blend it slightly darker than the scud back material. Make a dubbing loop and make a small thorax (SMALL). Next, take 3 fibers from a pheasant tail feather. Useing Water based minwax I rub them one to hold the fibers together. and place them on one side of the fly angled back and slightly down hold them on with only one wrap. Now, do that again for the other set of legs. You'll be able to pull them up and into place because you only used 1 wrap.
When you have that done snip the butts of the pheasant feathers off.
Pull the strech-flex over the eyes and take one good tight wrap. Pull the stech-flex rearward and take 2 wraps directly behind the eyes. Whip finish color your thread to match in and coat with Min-wax.
Cast this fly into the weedy edges and twich in towards you. If you tye in the tail it will have a beaver tail effect on the swimming of this fly and produce more strikes.My friend Tom and I really did well with this pattern in Late May- July last year.I just noticed that This fly was tied useing Marabou in the thorax. Substitute the seal fur for this if you don't have any fur dubbing material and want to tye one up quick.
