The Yellow May Klinkhammer Barbless is a brilliant, parachute emerger for Yellow May activity on suitable UK rivers. Its pale yellow body hangs through the surface film while the hackle and post hold the fly at the emergence point.
Use it when yellow duns or emerging naturals are visible, commonly in late spring and early summer where the species occurs. Fish upstream on a leader with a drag-free drift and treat only the supporting hackle. An excellent fish catcher - few moments beat watching a trout lift and take it cleanly.
