Olive Upright

Fast-water upright olive
Trout · GraylingSurface

A yellow-olive upright dun for fast, stony rivers — the clinger nymph's brief, exposed moment on the way to the bankside stones where it hatches out.

Fish this when

During the Olive Upright hatch on fast, stony-bottomed rivers from April through summer, when duns are riding up through broken riffles rather than the flatter glides.

Why it works

The upright wing throws a clean silhouette against broken, light-scattering water that would blur a flush-riding pattern, matching the natural in exactly the fast rocky habitat this clinger nymph needs to survive.
