Run the thread down to a place opposite the barb and catch in a bunch of white marabou. This is a small slim fly so the bulk on the hook shank needs to be kept at a minimum. Run the thread back and forth along the hookshank to produce a neat level body.
TIP: When preparing the marabou, place the marabou tips in your left hand between index finger and thumb and with the right hand move your thumb and index finger nails down the marabou stripping the webby marabou bulk off the stems. This will result in a slimmer body when tied in.
Wind the dubbing back to the where the tail is tied in and then dub forwards to about 1/4 of the bodylength from the eye. At this point use a dubbing teaser to tease the fibres out making a 'buggy' body.
Now take a bunch of Marabou for the wing. I use the fine tips found at the top of the Marabou feather, the same principal as that used in the Cormorant lure. Tie in the bunch of Marabou just behind the eye of the hook and trim the waste feather. Whip Finish the thread.
