Dry fly hackle Grizzly hackle (1 feather, sized to hook)
How to tie it
Lay a base of black thread down the shank to the start of the bend.
Tail: mix a few grizzly and a few brown hackle fibers, tie them in a little longer than one hook gap, check the position and bind the butts forward as you return the thread to the rear.
Wax the thread and dub a thin noodle of Adams gray dubbing. Wrap a slightly tapered body forward to the 2/3 point of the shank; it may take two noodles.
Wing: clean the underfur out of a stacked clump of deer hair and measure it about one body length. Hold it on top of the shank with a pinch wrap and add two tight wraps. It will want to spin, so keep tension up and toward you.
Take one thread wrap underneath the wing to prop it up, then take one wrap around the hair bundle only (not around the hook) to cinch the wing and stop it rolling. Add two more securing wraps.
Unlike an Elk Hair Caddis, trim the butt ends off close to the shank, then run a few wraps through the stubs; lift any strays with a fingernail or bodkin and trim again.
Tie in a brown and a grizzly dry fly hackle together at the front of the body, starting them almost perpendicular, pull them back, add wraps behind, and trim the stems.
Wrap two turns of the grizzly, then follow with three turns of the brown for a mostly brown collar with a little salt and pepper in it. Tie both off and trim.
Sweep any forward-pointing fibers back with your fingers, take the thread to the eye and build a small tapered head - 10 or 12 wraps will not hurt the fly.
Whip finish without trapping hackle fibers and add a drop of head cement.
