Overview
The Bonefish/Redfish Crab can be tied in different colors to match the local crab species. The Solarez Bone Dry UV resin is used to create a realistic shellback that adds durability and gives the fly a glossy finish.
Materials
Hook: Tiemco 811S, size #2–#6
Thread: Chartreuse UTC 140
Eyes: Small Gold or Silver Brass Eyes
Butt: Olive Cactus Chenille
Tail: Tan Polarfiber
Body: Sand or Tan EP Fibers
Behavior & Presentation
Natural Behavior: Small crabs scuttle sideways in rapid bursts when exposed, attempting to re-bury or hide under structure. Tidal movements expose these crustaceans on flats where they forage, making them vulnerable to hunting gamefish.
Where Trout Eat It: Bonefish and redfish hunt systematically across flats, mangrove margins, and tidal pools during tidal movements.
How to Fish It: Present near bottom with slow, bouncing retrieve to imitate fleeing crab behavior.
Best Water: Target shallow flats, mangrove edges, channel swings, drop-offs, and tidal pool structure.
Strike Type: Gamefish tip down and crush this crab imitation against the bottom, producing a distinctive heavy pull followed by a run—strip-set multiple times when you feel pressure.
Fishing Strategy
Rigging Suggestions: The Bonefish/Redfish Crab can be fished alone, or as part of a multiple-fly setup with a shrimp pattern trailing behind.
Seasonal Timing: Effective during peak feeding periods when water temperatures and conditions support active feeding behavior.
Pro Tips: The Bonefish/Redfish Crab is a sinking pattern. The bead chain eyes help get it down to the bottom quickly, and the tan color helps it blend in with the sand or mud bottom.
Entomology
Small crabs inhabit shallow tidal flats and mangrove edges, burying themselves in sand or mud during resting periods but emerging to forage during tidal movements. When exposed by receding water or detected by hunting fish, crabs scuttle sideways in short, rapid bursts before attempting to re-bury or hide under structure. Bonefish and redfish have specialized feeding strategies for crushing these armored prey, making crabs a staple food source despite their defensive capabilities.
