Here is the fly pattern sheet for the Jimmy Legs nymph. It’s also known at Pat’s Rubberlegs. I read where is difference is Jimmy Legs uses knotted legs. I believe it would catch more fly fishers than fish, so I don’t knot the legs.
I don’t know why the Jimmy Legs works as an imitation for a Golden Stone nymph, but it does. Here is an image of the real nymph.
Daiichi 1720, #10
6/0 or 8/0 brown or olive
.020 lead wire
Medium variegated chenille – brown/olive or olive/brown
Crazy Legs – olive or brown
Here is a link to a Youtube video by Skyler Hardman who does a terrific job tying the fly.
Thanks John looks good
