The Foam Back Killer Shrimp Barbless Size 10 is a highly effective, substantial stillwater shrimp pattern intended to suggest large freshwater crustaceans, including the highly invasive killer shrimp where it occurs. Trout can exploit these protein-rich food items around weed, stones and margins.
The foam back alters the fly's profile and can help it fish with a slightly lifted or controlled attitude rather than simply lying flat on the bed. Present it slowly near structure, beneath an indicator or with short draws and long pauses. One positive take is often enough to make this a trusted box favourite.
