In South Africa, caddis patterns are probably the most effective pattern across the board for yellows on the Vaal and Sterkies, and for trout in rivers and still waters. That?s not to say there aren?t more effective flies for each of those fisheries, because there are, but few are as versatile as the Caddis.
Emerging caddis flies are most vulnerable when they are breaking free of the shuck in the film and trying to dry their wings. Anglers who have been fly fishing this pattern have given it great reviews on its effectiveness as it hangs in the water.
The CDC gives this fly just a bit a buoyancy to keep it in the top of the film.
The orange hot butt adds an extra attractor to this fly.
