Dawson's Olive Lure Size 10 is a highly effective, classic British stillwater pattern associated with damselflies and other olive aquatic food. Its mobile profile makes it effective around weed beds, margins and drop-offs.
Fish it on a floating or intermediate line, allowing it to sink before using a slow figure-of-eight or short pulls with pauses. Keep the retrieve restrained when trout are feeding naturally. Wait for the pause - that sudden pull is what makes fishing this style of fly so addictive.
