Recipe for a Lightning Bug
Not only are these bugs irresistible to the trout in western Montana - they look like some bad ass cybernetic Shinya Tsukamoto creation!
Thread: 6/0 to 8/0 - Any color will do
Hook: #14 to #18 curved nymph hook
Tail: 6 pheasant tail fibers 1 hook shank long
Rib: Fine Copper wire (Red looks even better)
Abdomen & Wing Case: Holographic Tinsel
Thorax: 3 to 4 strands of Peacock Herl (or if you want a buggier bug use a shaggy dubbing like Scintilla)
This fly is an "attractor" pattern and doesn't imitate any kind of bug known to man - at least I hope it doesn't.
Fish it as a dropper off a #14 to #12 Pheasant Tail or Prince Nymph in the fall and winter months. In the summer fish it with a smaller #20 nymph such as a Brassie as your dropper.
