We idolized Shane Stalcup when learning how to tie. His book, Mayflies, is a classic. The Gilled Nymph was, according to Mt Stalcup, his favorite. The original technique is to wrap the ostrich forward and then rib with wire. Then, a bodkin is heated and the top and bottom ostrich fibers are singed to create a flat body while leaving "gills" on either side of the body. It is not a difficult technique. That said, Mr Stalcup was also a fan of V-Rib (also known as D-Rib).
Regardless, the star of the show is the ostrich. The ostrich creates gills, which come to life in the water. Here's our take on the gilled nymph:
Here's our take on Bubba's, which is a callibaetis pattern with a devoted following of lake anglers throughout the mountain west. We think it probably works everywhere.
The Mottled Turkey tail fibers make a great body. The barbs create gills and the coloring is....well, natural. That said, this type of body can be fragile. To help durability we add a drop of glue on the hook shank before wrapping the turkey forward. We also counter rib with gold wire. An alternative is to use a tight, slim dubbing noodle of Hare's Ear.
But, the real star in our opinion is the Ostrich. Ostrich is a great material with really good movement in the water. Here's how we piece together Bubba's:
