CDC Midge Cluster

Griffith-style midge cluster
TroutSurface

CDC midge cluster suggesting a knot of hatched adults on the film; a tiny calm-water surface fly.

Fish this when

Dead-calm water during a heavy midge hatch, when naturals bunch into mating clusters rather than sitting singly.

Why it works

The clustered CDC-and-hackle profile reads as several midges knotted together, matching what fish are actually keyed on rather than a lone adult.
