The Sooty Olive Fly from The Art of Angling by William Blacker. The one above is tied in hand on a vintage blind-eye hook, while the three below all are tied for fishing on Ahrex FW580 #10.
I found a deep green hackle deep in my hackle box that really matched the mohair in the body. A patch that I didn’t remember, but showed up just in time for this pattern that I believe in: the color, the movement and shape should give plenty of trout this summer! A variant should be a spider-version without the wing
