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 Green Drake (Ephemera guttulatais) one of the largest mayflies available to trout. They hatch mid-day, and will cause trout to completely abandon any other type of food. The nymph emerges to the surface of the water quickly, and after drying its wings, flies off. This leaves little time for trout to grab a bite, so they become very opportunistic when they see the Dry Ice Green Drake fly pattern.
