Isonychia Dry Fly Mayfly

The Isonychia (also known as Great Western Leadwing, Slate Drake, Leadwing Coachman, Dun Variant, Mahogany Dun or Iso) are found in many rivers of the U.S. They can first appear in June, and the hatch can extend through October. The body is olive to brown, with grey wings. These are big mayflies so you can match the hatch with #8 - #12. Good Spinner falls occur in the morning or evening.

The mahogany dun imitates the adult Isonychia bicolor mayfly. Brown drakes are a burrowing type of mayfly, but when they hatch, trout key in to this large trout fly. 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!!!
