Muddler heads fly fishing
The first documentated muddler minnow pattern goes back to 1926 in US. Even though nowadays muddler might sound synonimous of cone-head shaped deer hair fly, apparently the models in the early years did not have a thick bulky head but more sparse trimmed hair. This unweighted version is fished on floating lines as well as on sinking lines, imitating primarily a fish (gobius) but in the smaller hook sizes a big sedge or stonefly. Here below the original dressing:
hook extra long size 1 - 12, tail: mottled turkey, body: flat golden tinsel, underwing: sparse gray squirrel, wings: mottled turkey, head and hackle: natural deer hair
