The CDC Hopper Olive Barbless Size 12 is a highly effective, buoyant terrestrial dry fly for trout taking small crane flies, hawthorn flies, heather flies and other land-bred insects. Its olive body is less conspicuous than brighter hopper patterns, while CDC provides a light footprint and subtle movement.
Fish it near bankside cover or along stillwater wind lanes where terrestrials collect. Start with a natural drift and add only an occasional twitch. The strong Ahrex barbless hook suits confident takes, while the size 12 profile remains substantial enough to see in broken water. Placed accurately, it gives you every chance of seeing a trout commit at the surface.
