The Thunder & Lightning is one of the classic Scottish salmon flies, famous for its bold contrast and effectiveness in both clear and slightly stained water. Here’s an overview of the pattern:

Notes

• The yellow rear body gives the "lightning" flash, while the black front body and hackle provide the "thunder" contrast.

• The mallard wing and golden pheasant topping give it that classic swept salmon fly silhouette.

• This fly has been used for well over a century on rivers like the Dee, Spey, and Tay, and remains effective in Atlantic salmon fishing today.
