I found a great step-by-step tutorial and some tips for building a better stonefly nymph on FlyTyer.com that I wanted to share. The tips are more in the form of information, but having a clear insight into the natural insects is key to imitating the most important elements fish target. Click here for the article.
Nadica’s Stonefly Nymph – Igor and Nadica Stancev
Hook: Tiemco TMC200R, sizes 10 to 4.
Head: Gold or brass bead.
Thread: Cream 6/0 (140 denier).
Weight: Lead wire.
Butt: A fine, flashy dubbing such as Wapsi Fly’s Super Bright Dubbing, but you may substitute your favorite brand of fine-fibered dubbing. Common Antron dubbing is an excellent choice.
Tails: Stripped hen or cock body quills.
Abdomen: 4-millimeter-wide latex strip such as Hareline Dubbin’s Nymph Stretch Skin.
Wing cases: Brown partridge, hen, or grouse feathers.
Thorax: Rabbit dubbing guard hairs. Brush out the underfur before placing the remaining material in the dubbing loop.
