I call this one The Spartan. It is based on a Hornberg but instead of using two mallard flank feathers on each side of the fly, I use one on the top.
You fish as you would any streamer and the larger trout at the private lake I fish prefer the pattern during the morning and the Fall when the mosquito fish are available.
Hook: Tiemco TMC 5262 or similar 3X long, heavy wire streamer hook, size 2-4
Thread: Black 8/0 - 14/0
Head: Small-medium size black cone head
Body: Flat silver tinsel
Underwing: Red and yellow dyed buck tail fibers, sparse
Overwing: 1 mallard flank feather
Slide on the cone head and attach the hook in the vise. Tie in a length of silver tinsel.
Tightly wrap the tinsel to the rear of the shank, stop above the hook point, reverse direction and wind the tinsel back to the starting point. Trim away excess.
Tie in a sparse number of red buck tail fibers. They should extend a little past the hook bend. Clip away butt ends.
Tie in the same amount of yellow buck tail fibers so they extend the same as the red fibers. Clip away excess.
This one is difficult to explain. You want pick a mallard feather that is in proportion to the pattern.
Choose a feather with the stem running directly down the center so the fibers are equal on both sides.
Tie in the feather over the buck tail so the fibers follow the hook shank. Clip away excess.
Prepare a grizzly hen feather that is fairly long and webby. Tie in for the collar.
Wrap the collar and whip finish.
With any luck, you'll end up with something like this:
The red and yellow buck tail fibers will give a hint of color under the mallard flank feather when the pattern is wet.
I hope the pattern works as well for you as it does me.
