Here is a pattern which has its beginnings in the Ammonite nymph but is a simpler fly to tie and is less heavy for those occasions when the fish are up in the water.

Hook:  Grub hooks such as B100 or a tiemco 200 R for a different body shape altogether. The size will be to match the hatch.

Body:  Olive tying silk.

Thorax:  Hares mask (dubbed) or dubbing of choice

Thorax Cover:  Either 0.5 mm black foam or pheasant tail fibres (Shown)

Sally Hansons Mega Shine Nail varnish

Tie on the silk to the hook using a jam knot.

Wind the silk up and down the rear half of the shank creating a nice tapered body. I have used uni nylon silk in this pattern and then dyed it olive with a dye pen.

Take some lead wire and wind it on the thorax for weight. you do not have to do this if you want a drifting emerger nymph.

Cover the lead wire with silk.

Take about 12 fibres from the centre tail feather of a cock pheasant and tie them in by the butts. These will form the thorax cover.

Attach your dubbing and apply it to the thorax. Once the dubbing is on then brush it downwards and back with a soft brush such as a clean mascara brush or toothbrush. This will form the legs of the fly.

Draw forward the pheasant tail fibres and form the thorax cover.

Remove the waste and tie off with a whip finish.

Now take the Sally Hanson Mega shine varnish and apply it to both the thorax cover and the body but not the dubbing.

Several coats of the varnish will be needed to build up a bright glossy fly that will sink rapidly through the water to get to the depth of the fish.

Tight Lines.
