Oliver Edwards Ephemerella Nymph from his Masterclass Flytier

This tie instruction can in no way be compared to or replace the one
the author gives in his book especially his very descriptive hand
drawings. But anyway ... 
Hook:   Partridge GRS12K or K14ST size 18-20 (2x long curved shank hook).
Tail:   2x2 speckled barbs from a partridge tail quill.
Abdomen and thorax: Sparkle yarn, reddish medium brown/dark brown.
Weight: Very fine copper wire.
Legs:   speckled barbs from partridge tail quill.
Wing buds: black quill section.
Head:   2 tail barbs from a common (ringneck) pheasant.
Form the abdomen and thorax sections with the copper wire and flood it with head cement, then cover it with tying thread. For the tails tie in on the end of the shank a small 'button' with a tiny amount of dubbing material which will help spread the tail fibers. Tie in the barb fibers, two on each side and wrap the thread down to the button to spread the tails in a angle of 60 deg. Take two plys of yarn and use your nail to taper it down. Now tie the thread to the back of the thorax section and tie in the yarn lightly. Tie the thread back to the tails and pull the yarn backwards at the same time to catch most of the yarn.

I now tie in the black feather sections (4-5 fibers wide) at the back of the thorax (O.E. does this after the abdomen has been wrapped with yarn) and start wrapping the yarn in the direction which will tighten the yarn. Cover the abdomen first, go around the two upward pointing feather sections, then cover the thorax without any twist to the yarn. Now pull the two feather sections forward and tie them down on the front of the thorax.

The legs are created by cutting off the tip of the partridge feather and stroking back all the barbs except for the five pairs near the cut-off. These barbs will form a V. Tie in the feather on the underside of the hook (easiest with the hook turned upside down) and pull the feather forward to adjust the length of the legs. Use a nail to keep the legs spread out nicely while pulling.

For the head take one or two pheasant tail barbs, cover them lightly with flexible head cement and tie them in at the front of the thorax. Twist the barbs and wrap them around the hook, so they stack. Finally tie them off behind the head where they were tied in.
