The Diawl bach nymph is one of those patterns that is fast becoming a 'must have' fly in your flybox. It is tied to represent a beetle pattern (the exact interpretation is 'little devil), but it can represent a whole host of acquatic insects that the trout consider as food.
A standard pattern includes a copper wire rib along the peacock herl body. However, the pattern is often tied with other colours of holographic tinsel, that gives an extra flash in the water. I have taken the holographic theme a little further and tied some with other colours of holographic tinsel as a rib.
This set of five flies, all in size 14 comprise one each of; blue holo, green holo, red holo, pearl holo and normal copper wire as rib.
They are contained in a transparent lidded plastic box that could be used as a flybox. The set costs £4.60 including 2nd Class postage.Tied by myself in Challenge Flies.
