RJW Black Mosaic Diawl Back with JC

The Black Mosaic Diawl Back with JC is a highly effective stillwater nymph pattern, designed to offer a slim, natural profile with just enough contrast and attraction to draw confident takes. The black turkey biot body creates a defined segmented appearance, imitating a range of aquatic insects, while the mirage tinsel tag adds a subtle flash point that can be especially effective in low light or coloured water.

A thorax of mosaic black dubbing provides depth and texture, helping the fly stand out without overpowering the overall silhouette. Finished with a Diawl back for durability and a lifelike sheen, the fly is further enhanced with genuine jungle cock cheeks, adding a classic visual trigger that often converts interest into solid takes. This pattern fishes well on floating, intermediate, or sink-tip lines and is ideal for slow retrieves or static presentations on small waters and stocked venues.

This fly is tied by Ryan from RJW Flies using top quality branded hooks and materials.
