The Dawl Bach is a classic Welsh stillwater fly that imitates a wide range of aquatic insects, including midge pupae, nymphs, and freshwater shrimp. This version features a shimmering peacock herl body, soft brown wing case and tail, creating a natural, buggy profile that is irresistible to trout. It is a versatile pattern, effective year-round when fished on a floating or intermediate line with a slow, steady retrieve.
