Arculeo's Claws-Up Crab in Tan is a crab imitation from Rainy's, available in size 1 and 1/0. The raised-claw posture suggests a defensive crab, a trigger for aggressive feeders.
Present it to permit and bonefish on the flats. The defensive posture stands out in the water column and can provoke reaction strikes.
Permit are famously selective, so a natural drift with minimal false casting gives this fly its best chance.
