Klinkhamers are different from many other parachute dry flies in that the thorax of the fly is designed to hang down 'through' the surface of the water to imitate an emerging insect.
The abdomen serves as a trigger point which penetrates the surface film, which gets noticed by trout from great distances, even before any resulting surface footprint features.
The abdomen of the fly float is underneath the surface of the water to attract the fish and improve hookups, while the parachute hackle and CDC is on or above the surface of the water for visibility and floatation.
