For bonefish on the flats, shrimp and crab-style patterns are the core picks. Big Y Fly Co Bonefish Bitters - RIO is a strong shallow-flat shrimp imitation with a slow sink and bottom-focused presentation, which matches tailing or cruising fish in skinny water. The Fly Crate Mantis Shrimp and The Fly Crate Banded Shrimp are lightweight options for skittish bonefish and shallow flats where a soft landing matters. Postfly Squimp - 2 Pack is another subtle shrimp choice for clear water and picky fish. If conditions are tougher, Postfly Bonefish Junk- 2 Pack is a good all-around flats fly when fish are selective or the wind and tide make presentations harder.
Cast ahead of the fish and let the fly settle close to bottom. Use short, subtle twitches or very short strips rather than aggressive retrieves. On ultra-shallow flats, prioritize a quiet landing and keep the fly moving just enough to suggest shrimp or crab forage. For the bottom-oriented patterns, fish them where bonefish are tailing, cruising, or feeding over sand, turtle grass edges, and mixed bottom.
Switch to a heavier or faster-sinking flats fly when fish are deeper, current is stronger, or you need the fly down quickly. If bonefish are very wary in clear, skinny water, favor the lightest shrimp patterns and the softest presentation. If you want a broader bonefish box rather than a single fly, an assortment like Flymen Fishing Company NEW Bonefish Fly Assortment (15-fly) can cover shrimp and crab looks.
