The Adult Buzzer Olive Barbless represents a midge at the final stage of emergence, sitting in or immediately beneath the surface film. The olive tone is useful when the naturals have a green or olive cast and trout are cruising just under the surface, taking individual insects.
Present it on a floating line with a fine leader and allow it to drift naturally. It can be fished singly to rising fish or as the top dropper in a light buzzer team. One positive take is often enough to make this a trusted box favourite.
