Great Fall Western water fly, over looked hatch of Mahogany Duns. Nice addition to any fly box for all our local waters.
The mahogany dun imitates the adult Isonychia bicolor mayfly. This mayfly hatches twice during the year with intermittent hatches in between. Trout absolutely lose their inhibitions at the sight of this mayfly. Good luck!!!Tied on hook size 14 to 18
