Body Fritz / blob chenille (orange, sunburst, pink or white) (1 length)
Tag (optional) Fluorescent straggle or ice dub (few turns)
How to tie it
Start the thread and tie in a piece of bright buoyant foam at the front of the hook to form the visible 'bung' head/back, which both floats the fly and acts as a strike indicator.
Run the thread to the bend and tie in the Fritz/blob chenille.
Wind the blob chenille forward in touching turns to build a fat, buggy body up to the foam, brushing out the fibres.
Fold or secure the foam back over and lock it down behind the eye with a few firm wraps.
Whip finish and varnish the thread; trim the foam to a neat rounded head.
