The Diawl Bach Black & Peacock Nymph is a refined take on the traditional Welsh pattern, combining a dark silhouette with the natural iridescence of peacock herl. This colour blend produces a subtle shimmer beneath the surface, closely resembling midge pupae and other small aquatic organisms that trout feed on regularly in stillwaters.
The black elements create a defined profile in clear or lightly coloured water, while the peacock body adds life like depth and movement. Designed primarily for reservoirs, lakes and dams, this variation offers consistent performance throughout the season when trout are feeding on suspended or emerging subsurface insects. Its understated appearance makes it particularly effective in pressured fisheries where fish can be wary of brighter patterns.
Please note all of our fishing flies are barbless unless otherwise stated.

Why Choose The Diawl Bach Black & Peacock Nymph
Natural Contrast: The dark body and peacock herl create a realistic subsurface shimmer that closely matches natural food sources.
Proven Stillwater Pattern: Based on the classic Welsh Diawl Bach, this version maintains the heritage and fish catching reliability of the original design.
Effective in Clear Water: The balanced colour scheme makes it ideal when trout are feeding confidently but are cautious of overly bright flies.
Diawl Bach Black & Peacock Nymph Fishing Techniques
To get the best performance from the Diawl Bach Black & Peacock, try the following approaches:
Steady Sink & Subtle Retrieve: Allow the fly to reach the desired depth before retrieving slowly with a controlled figure of eight motion. Briefly hold the fly at the end of the retrieve, as takes often occur on the hang.
Team of Flies Setup: Fish it as part of a multi-fly cast. It works well on the middle or top dropper to imitate emerging insects, or on the point to maintain depth and stability.
Match the Feeding Mood: When trout are feeding gently, use a minimal and consistent retrieve. If fish are active, introduce slightly sharper pulls to imitate a rising or escaping pupa.
