McCoy's All Day Isonychia Spinner Fly 12

The All Day Isonychia Spinner is a great searching pattern and is one of Ed's go to favorites to target rising trout during an Isonychia Spinner fall.

March Brown S12 Fishing Fly, Dry Flies

The Isonychia hatch is one of the best and most lengthy hatches in northern Michigan. This fly is designed, much like the name, to be fished all day! It has a very realistic profile and is a great fly to fish over rising fish. This is also a great searching pattern throughout the day with or without actual bugs on the water.
