Yes, a version of the ubiquitous Woolly Bugger, The Little Fort Leech. Without question, and for whatever reasons, the best dark WB I have ever used. Yes a basic black or dark brown WB will produce, as will almost any colored body combination given the right location and presentation. However, this pattern can be fished wit confidence on stillwaters and rivers. Simple to tie, this variation has a variegated marabou tail rather than the traditional Black marabou with a bright splotch of red hackle or marabou tied atop the black. The abdomen/thorax is lightly palmered with dark brown hackle. It is unweighted save the bead head. I tied this fly on a stout size 8 hook. I came upon this pattern about 20 years ago in Little Fort, British Columbia at a fly shop and have never stopped tying this very basic fly.
