The Stone
This fly was originated to imitate the needle flies (Leuctridae species of stoneflies) that are on the Yorkshire waters from February through to the end of November.
It is a very simple fly to tie and is better rough than tied ‘nice’. This fly fishes right in the surface and when the needle flies are on the water, this is a killing fly. I often give them to other fly fishermen and tell them to tie it on behind a tree. The fish seem to devour this fly and the take is usually vicious and the fly is often well down the trout of the fish. One of my standard ‘go to flies’ for late summer fishing.
