The Diawl Bach Copper Nymph is a modern variation of the classic Welsh pattern, incorporating a copper rib to enhance subtle flash and definition beneath the surface. Retaining the slim, natural profile that makes the Diawl Bach so effective, this version adds a fine metallic accent that reflects light and improves visibility without overpowering the fly’s realistic appearance.
The copper ribbing creates segmentation along the body, closely imitating midge pupae and other small aquatic insects commonly found in stillwaters. This balanced combination of natural materials and understated flash makes it a dependable choice when trout are feeding on suspended subsurface insects. It performs consistently throughout the season and is particularly useful when fish require a slight visual trigger lightly coloured water.
Please note all of our fishing flies are barbless unless otherwise stated.

Diawl Bach Copper Nymph Fishing Techniques
To achieve the best results with the Diawl Bach Copper Nymph, consider the following methods:
Measured Sink & Slow Retrieve: Allow the fly to sink to the required depth before retrieving steadily with a smooth figure of eight motion. Pause briefly at the end of each retrieve, as trout frequently take the fly as it hangs.
Multi-Fly Presentation: Fish it as part of a team on a multi-dropper leader. It works effectively on the middle dropper to imitate emerging insects or on the point to maintain depth control.
Adapt Retrieve Speed: In calm or pressured situations, keep the retrieve slow and consistent. If trout are actively feeding, introduce slightly sharper pulls to suggest movement from a rising or escaping pupa.
