Sometimes you need to go big, thus a giant nymph fits the bill. My own pattern I've came up with. Dorsal Ventral Ingredients: Any 3x long hook should work: #4 hook 6/0 Brown MFC thread. Mercer's Buggy Nymph Dubbing Dark Stone mixed with a lighter shade of brown. .25 lead-free wire wrapped from right behind hook eye to point of hook. Legs: Any black nymph legs. Tied an overhand knot for each leg then carefully tied in. Tails & Antennae: Trico Brown Turkey Biots. Carapace and Wing Case: Brown Swiss Straw colored with dark brown waterproof marker. Ribbing: Copper Brown Wire, smaller size. Eyes: Monofilament melted with lighter and colored black. Not for the beginner fly tier.
