I use a pattern I've dubbed the Snowshoe Emerger/Cripple. It's based on Quigley's Cripple. A friend visiting from California had a lot of luck with that pattern and left me one as an example. I changed it up a bit.
Hook: TMC 2488(or similar hook)size 12-20.
Thread: Black, or to match the pattern.
Tail: Rat Tail(you see it in fly shops as Frizz Fiber)
I use white and color it to match the pattern
Body: Pheasant Tail wrapped with thin copper wire.
Thorax: Yellow CDC feather
Wing: Snowshoe Rabbit
Hackle: Grizzly to match the pattern.
Tying Instructions
1. Tie in the tail/trailing shuck.
2. Tie in Pheasant tail, and thin copper wire. At this point you're
going to tie the body of a PT Nymph. I wrap PT forward and
counterwrap the wire. I would say you want the body to stop
about 1/3 the shank length behind the eye
3. Tie in a suitable bunch of Snowshoe for the wing with the
tips pointing forward. Trim the hair facing back short.
4. Tie in a yellow CDC feather by the tip
5. Tie in a grizzly hackle by the stem
6. Bring the thread forward to just behind the eye
7. Wrap the yellow CDC feather for the thorax.
I tie it down in front of the wing, and trim excess.
8. Make 3 or 4 wraps with the hackle over the thorax. Again I
tie it down in front of the wing, and trim excess
9. Build head and whip finish.
For the suplpur. I'd color the shuck/tail, tan or light brown. Body would be natural PT, Wing would be light gray. Hackle would be natural grizzly, lightly barred.
I may have a picture. If I do I'll post it
