I found this one while doing a GOOGLE search for Chironomids
Hook: Tiemco TMC 2302 – size 10 to 22
Thread: Uni 8/0, white
Abdomen and rib: Stretch Magic, 0.5 mm, Olive or Clear
Top Wing case: Mirage tinsel, large
Side Wing case: Biots, brown or color to match the natural
Gills: Oral-B ultra floss, white
Protective Coating: Loon Fly Finish Clear
I substituted Pearl Tinsel for the Mirage Tinsel,White Hi-Viz for the White Dental Floss, Red Flexifloss for the Brown Biots and Clear Cure Goo for the Loon Fly Finish. The end product is virtually the same.
When tying really small flies and you cant find a biot small enough, just look to a tail feather and use a single strand to get that fuzzy ribbing effect. Add some crazy glue th the shank prior to wrapping for added durability.
In the photo above, i used a single fiber from a turkey tail feather. Try using goose, swan, pheasant etc. thanks for looking
This is an old tips and tricks but may help the younger tyers.
Electrical cords make an excellent source of fine copper wire. Cut your cords about 4-6 inches long and leave a short amount of the insulation to keep it all together. Pull out a strand when its needed.
