Klinkhammer Black is the original caddis emerger but also represents a number of other emerging nymphs. We have these in a wide variety of colors to match the hatch. These pattern float in the surface film and can be fished static with an occasional twitch in flat water or dead drifted down the slower riffles. I used these to great success, last season on the Grand River in Ontario, Canada. This is a renowned pattern throughout most European countries but just as effective in North American waters, the Black Klinkhammer emerger is deadly for both Grayling & Trout.
