Colours to suit natural. Take three inches of poly yarn, tying it in as a short tail to start with, then binding it along the shank up to the eye. Leave excess pointing out over the eye of the hook. Now dub the 'waste' end of the silk lightly and wind this up the shank to form a neat, slim body and tie off just behind the eye. Tie in the hackle.
Wind hackle down to the point where silk is hanging and tie off.
Bring yarn over hackle to produce a thorax and tie down with a couple of turns and whip finish. Clip off any hackles pointing up or down. Cut wing to length to reach just behind the tail. Rod Av. 2.8. All lakes fishing well with good takes reported.
