A pattern I found in Dave Hughes book Wet Flies.
A simple pattern with a history of taking trout.

The pattern calls for silk thread for the body, hares dub for the thorax, and a grouse feather for the hackle.
The top fly is tied with traditional silk thread and the bottom is tied with cotton thread.
