CDC Trico

Micro trico dun
Trout · GraylingSurface

Tiny CDC-winged Trico dun for the dense late-summer morning hatch.

Fish this when

The short, dense trico dun emergence on calm summer mornings, before the spinners take over and the real carnage starts.

Why it works

A single sparse CDC wing keeps the fly proportioned like the naturals it's swimming among, avoiding the bulkier silhouette that stands out — and gets refused — in a hatch this thick.
