Black Gnat & Peacock Spider Dry. A highly popular fly replication that will create stunning results in both the shallows or in the deeper waters. The unusual formation of the hackle produces a rippling effect that is sure to catch the eye of all the ambitious fish in the area. The colors used on this fly make it a highly popular choice for all the Canadian and U.S. early season fishermen. I have personally used the Black Gnat and Peacock Spider Dry to great success on the Grand River in Ontario releasing three brown's over 19".
