This is a fantastic nymph pattern that has given me great sport on the rivers over here right through the season . simple enough to tie, well worth a try . as you can use the same pattern for most nymphs just vary the size and colour.
Wind on some lead wire
This

Next secure the lead and take the thread back to the hook bend.

Tie in a strand of silver wire.

Now dub on a lenght of olive rabbit fur.

Wind on the dubbing half way up the hook giving it a nice tapeed look.

wind up the silver wie about four turns andtie down.

now tie in a nice bunch of cock pheasant tail fibres.

Cut of the excess and dub on more rabbit fur for the thorax.

Pull the pheasant tail fbres forward and tie down.

Divide the phesant tail fibres evenly to each side of the thorax.

now pull back down the fibres with your finger and thumb puling them under the thorax and tie down.

then whip finish and varnish the head.
