Featured Fly Pattern: Señor Crab

Whether you are targeting Permit in South Florida and the Caribbean or Sheepshead in North Florida, Señor Crab is here to help!

Inspired from the traditional flex crab pattern- this fly can be color customized when tied to tailor the waters you're fishing.



There is much versatility in this fly. It can be tied small or large, tan or dark brown, red or blue claws. Not only is it imperative to have in the box for Permit and Sheepshead, but candy for Bonefish and Redfish as well.

The weight of the fly is concentrated in the inside of the flex material, it is the first material you tie on to the hook. If targeting permit in deeper water off the edge of the flat, tying on a lead eyes works best. If targeting bonefish on a skinny flat, it is best to tie a small lead or bead chain eyes as the base weight. What makes this fly pattern tricky to tie is wresting the flexo material and use of a cautery tool. It is not recommended to cut flexo material with your traditional bench scissors, once threaded it is best to burn excess material with the tip of a cautery tool to burn it off.


Once flexo material is established, the use of the threader and good glue is needed to string legs, claws, and eyes through the flexo material. It is imperative that legs and claws that are too thick are not used because it will rip a hole through the delicate flexo material. Traditional shrimp eyes can be glued through the material, use all appendage material scaled to the size of crab you're tying. Once finished with threading the material, a sharpie of your desired color can be used to tie spots on the body or color the claws.


This fly can be used all year around for permit, sheepshead, and redfish n any destination. However for bonefish, I recommend having this in the box in the summer time. Big shrimp runs pass through the winter time, and that is when bonefish gorge on shrimp the most. Especially in Biscayne Bay, big bonefish will patrol the flats in search for small crabs.


This fly is best worked on the bottom with long sliding strips just as a crab would crawl on the bottom. However, permit often eat their prey as a crab is sinking to the bottom. Hone your flexo crab lands in front of a permit, small slides to catch its attention, and once spotted let the fly sink and Mr. Permit will eat on the way down or once crab touches the bottom 😁


Señor Crab is single handedly the most realistic crab fly you can have in the arsenal. In addition, one of the most intricate flies to tie at the bench.

Suggested hook sizes:

Juvenile Tarpon, Redfish, and Snook: Size 2

Bonefish and Permit: Size 4

Bigger Tarpon: Size 1/0, 2/0
