PMD Emerger
Tying instructions:
Tie in woodduck fibers, then add sparse Zelon tail directly on top of the woodduck. Tie in biot for body with "notch" up so ribbing is prominent when wrapped. Wrap body forward to about a third of the shank length back from the eye. Add sparse underwing of medium dun Zelon, then tie in sparse overwing of medium dun CDC. Finish with 4-5 wraps of dubbing to form thorax.
Notes:
The PMD emergers are a staple of my Henry's Fork box. I carry about a half dozen variations, but the pattern shown is my "full dress version. The underwing of Zelon seems to help the CDC stand a bit more upright. The woodduck fibers seems to add a look of segmentation to the shuck/tail
