Chernobyl Ant

Big-water foam attractor
TroutSurface

A slab of foam, a few rubber legs, and not much else — the fly that taught a generation that trout will eat a chunk of craft foam if it lands with a plausible plop. A Western big-water staple, fished alone or as the buoyant anchor of a hopper-dropper.

Fish this when

Summer on Western freestone rivers and tailwaters, prospecting banks and seams or as the indicator fly above a nymph dropper. Twitch it occasionally to suggest a struggling terrestrial.

Why it works

Big foam terrestrials sit unsinkable in rough water and present a large, leggy silhouette that opportunistic trout move for. As a hopper-dropper anchor it both catches fish and floats a nymph at depth.
