A segmented turkey-biot abdomen with a fine wire rib, squirrel thorax and turkey wingcase.
The source index calls one photograph “Biot Nymph, Black” but does not identify the photographed dressing. This page presents Nicole March’s separately documented golden-brown Turkey Biot Nymph as a specific exemplar. Its color and materials are not claimed to match the black source fly.
Work through the numbered steps in order, using the materials list and written proportions as your guide.
01
Set the tail and rib
Start tan thread and tie three or four partridge fibers at the bend, about a shank length long. Bind fine gold wire along the side of the planned abdomen.
02
Tie in the biot
Attach a golden-brown turkey biot by its tip with its notch and translucent edge facing down. Build a smooth, slight thread taper underneath.
03
Wrap the ridged abdomen
Fold the biot so its ridge faces the bend, then wind it forward in close turns. Tie it off with roughly one eye-width of front space left.
04
Lay the wire between ridges
Spiral the fine gold wire forward in the valleys between the raised biot turns. Secure it at the abdomen front and trim the excess.
05
Prepare wingcase and thorax
Tie a narrow turkey-tail feather section on top at the front of the abdomen, pointing rearward. Make a dubbing loop filled with natural squirrel and wind a fuller thorax.
06
Close the wingcase
Draw the turkey section forward over the thorax, secure and trim it. Form a neat thread head, whip finish and optionally coat only the head with black lacquer or UV resin.
Beyond the bench
On the water.
Drift the nymph below the surface when mayfly nymphs are active, adjusting depth with the rig rather than adding unlisted weight to this documented dressing.
