The mallard and claret fly is a very traditional fly and good early on in the season on still waters and rivers. Use when it is not so warm and perhaps some colour in the water. Accredited to William Murdoch of Aberdeen. The Mallard and Claret Wet Fly is probably the finest all round still water pattern you will have in your fly box throughout the year, fished as the top dropper or on a single it certainly kills trout. Works well on both rivers and large still waters when dark bodied sedge's are hatching. It is generally fished as part of a team of flies just under the surface.
