Extended Body Hex Mayfly
submitted by Elaine Cook

Starting in late June and extending well into July, the largest species of Mayfly emerges in a number of waters in Northeast California including Lake Almanor, Manzanita Lake, and Fall River. The insect leaves the mud late in the day, swims to the surface after the sun has set, and spins aggressively for a minute or two to free itself from its nymphal shuck. The big boys come out for a feast! Be sure to have a few of these with you when you venture out.

Hook:TMC 100, size 10
Thread:Yellow, 6/0
Wing:Yellow dyed deer hair, fibers thin and not porous
Tail:Moose body or tail
Body:Yellow dyed deer hair, porous fibers about 2" long
HackleYellow dyed grizzly, barbs two times hook gap

1. Crimp barb and attach thread 1/4 back on shank.
2. Wing details: Select a bunch of hair about the size of a wooden match. Clean out the under fur. Stack tips. Tie onto hook shank, tips extended beyond eye so that wing equals length.
3. Tail details: Select about a dozen fibers. Clean out under fur and short fibers, stack tips. Return thread to rear of shank. Tie in moose with tips to the rear and extending two hooks lengths beyond shank. Cut butts at an angle and bind onto top of hook shank.
4. Body details: Move thread to behind eye. Select clump hair about the size of two wooden matchsticks (after cleaning). Clean out under fur. Stack tips. Tie in with tips extending beyond eye equal to 2 times the hook length. Pull snugly allowing the hair to flare. Make several more wraps and cut butts. Move thread in front of wing. Facing the front of fly, use a bodkin to divide body on top of shank and stroke backwards on sides and bottom of fly, holding wing upright. Using half-hitch tool, push body backward. Make one wrap in front of wing and one behind wing. While continuing to hold body material along shank out from tail, make wide turns like a barber pole along shank, then continue wrapping the body only until near the end of the body material. Make three wraps in the same spot, then wrap forward in wide wraps like a barber pole in front of wing. (Note: the wraps will appear to crisscross.) Cut tips of body material beyond last wrap of thread. (See diagram.) Cut all but 4 or 5 hairs.
5. Hackle detail: Cut fuzzy ends off hackle. Cut 3-4 fibers short at end of stem. (crew-cut). Wrap in at base of wing shiny side toward you. Reposition thread by wrapping clockwise around base of wing leaving the thread hanging in front of shank. Attach hackle pliers to hackle top and let hang in front of shank. Make 4-5 wraps of hackle around base of wing. Half hitch thread at base of wing to tie off. Cut thread and hackle. Lift hackle in front and apply drop of head cement. Reshape wing and hackle into place.
