If you have ever fly fished for permit, you are well aware of their finicky if not infuriating nature. Unpredictable, ultra-picky, and borderline paranoid, permit fishing brings us the highest highs and the lowest lows, driving many anglers mad with love, hate, and everything in between.
This article will look at 13 of the world's most popular, reliable permit flies for use around the world and regional considerations for planning your fly box.
1. Raghead Crab
The Raghead Crab is a time-tested permit fly that has earned its place as a staple in saltwater fly boxes across the Caribbean and beyond. Designed to imitate small crabs found on turtle grass flats and sandy bottoms, its wide, soft body and splayed rubber legs create a realistic, lifelike profile that moves naturally in the water. Equally effective for permit, bonefish, and even triggerfish, the Raghead Crab remains a favorite among guides for its simplicity, durability, and consistent ability to get eats. Strip it slow and hold on.
Traditionally tied with glued sections of synthetic yarn to form the body, the Raghead has seen countless variations over the years. When at rest or slowly stripped, the splayed feathers at the rear mimic a crab’s claws raised in a defensive posture—a key trigger for wary permit. Variants like Doug McKnight’s ER Crab (Easy Raghead) use furry foam for a faster, cleaner tie, while other popular materials include McFly Foam, EP crab bodies, crab coins, and even trimmed scraps of craft fur. However you choose to tie or buy it, the Raghead Crab is a proven producer and one fly you never want to leave behind.
2. Alphlexo
Designed by Signature Umpqua Tyer Alec Gerbec during his time on Alphonse, the Alphlexo has quickly become a permit and triggerfish staple, as well as a killer pattern for big bonefish. The profile of the fly is perhaps the most realistic of any crab currently on the market, and continues to catch permit well beyond its origin point in the Seychelles.
The body is comprised of body tubing tied in at both ends, a product originally intended for use in large baitfish patterns for predatory fish such as pike or musky. The result is a durable, realistic body profile that is also hollow and incredibly light. The alphlexo comes in a ton of different varieties, and you should opt for whatever color closely matches the bottom of the intended fishery.

A saltwater staple for bonefish, permit, and any species that eats shrimp. The use of shrimp versus a crab fly when targeting permit is going to vary, but they do have one big advantage. When fishing a crab, the fly is generally stripped very slow, ticked across the bottom, or in some cases, left alone entirely. This means that if there is any slack in your line, you may never even feel a permit eat your crab fly before it spits the hook.
With a shrimp pattern, you are often stripping the fly allowing you to maintain good tension, therefore making it much easier to know when the fish has committed.
The orange casing at the tail of the fly acts as a trigger point for hungry fish as it resembles the egg sac of a spawning shrimp. The fly comes in a number of colors, from white to olive, and is one of the best "crossover" flies when targeting bonefish, permit, or triggerfish on the same flats.
4. Avalon
The Avalon was created specifically for permit within Cuba, but it has proven to be a great pattern throughout the Caribbean. However, if you are heading to Cuba, it is very likely going to be one of the first flies your guide asks you to tie on for both permit and bonefish.
When stripped, the splayed pieces of rabbit strips on the Avalon undulate in the water, and the strips of pearl diamond braid ensure the fly gets noticed. The fly is generally quite heavy, but is well-balanced through the use of a keel.
The keel is a piece of monofilament tied in from the bend of the hook up to the eye, threaded with stainless steel beads. The result is a fly that does not spin when stripped, perhaps the single greatest giveaway to a curious permit that a fly is not worth committing to.
The Avalon comes in two weights, and we suggest having a couple of each for targeting fish on calm, shallow flats as well as deeper water for cruising fish.
5. EP Crab
Enrico Puglisi's EP Crab is a popular permit fly, and for good reason. The body of the pattern consists of synthetic EP fibers, that are durable and shed water well. The fibers are layered, making for a realistic mottled appearance in the water similar to a crab's camouflaged carapace. The back of the fly, or the "mouth," consists of marabou for good, natural movement and krystal flash for "feelers."
This style of crab was popularized by Del Brown's merkin, where a synthetic material is layered down the shank with x-wraps and then trimmed to shape. This is a big pattern to have for travel to the Yucatan, especially with the use of the chartreuse thread which most Mexican guides prefer for their permit flies.
The Strong Arm Merkin is a Dave Skok pattern designed in the Florida Keys. The pattern was a revolutionary pattern in the region and has since been delivering permit to hand all over the world.
The Strong Arm's defining feature is the chenille claw extending from the back end of the body. The claw, or strong arm, serves multiple purposes. Firstly and most obviously, the claw is a realistic representation of a crab in a defensive posture hoping to deter a predator or latch on to a fish lip that comes too close.
Secondly, and potentially more importantly, the claw acts as a keel for the fly--keeping it more balanced in the water column as it falls. The result is a fly that moves and looks very realistic, routinely fooling many a permit in the Keys and well beyond.
If you're heading to Belize, this fly should be in your box. Originally developed by the lauded Will Bauer for the flats of Southern Belize, this fly is responsible for hundreds of permit to hand.
The Flats Crab is generally tied with Mcfly Foam, a synthetic material used for egg patterns for trout fishing. The decision to use Mcfly Foam was a smart one, as the material is known for quickly absorbing water and ensuring the crab pattern sinks. As much of the fishing in Southern Belize is done for actively feeding, tailing permit, a fly that can land softly but sink fast is paramount to success.
Another notable feature of the Flats Crab is its realistic profile, with its large rubber legs and crab eyes positioned to imitate how crabs actually move: side to side. For fly tyers, the original Bauer legs are hard to come by, but rubber bands or large rubber legs work just fine.

Similar to the Spawning Shrimp, the Mantis is a great crossover pattern between bonefish and permit. The Mantis Shrimp catches bonefish everywhere it goes, and is going to be one of your guide's first choices when selecting a shrimp fly.
For fly tyers, the original Mantis Shrimp is a resourceful pattern with very little waste. When tying, use your fingers or a comb to tease out the shorter fibers at the base of the craft fur. Use the longer fibers for the "head" of the shrimp (tied at the back) and the shorter fibers to use in a dubbing loop for the body. The result is a slender but realistic looking shrimp profile. If preferred, you could always utilize a premade dubbing brush to build the body to get creative or for ease of tying.
Del Brown caught over FIVE hundred permit on fly throughout his lifetime, a feat that truly boggles the mind. His signature crab pattern may appear to be simple when compared to some modern patterns, but it was a revolutionary pattern when he first designed it decades ago and still catches permit today.
There are a couple signature elements of Del's Crab. First, the use of a chartreuse thread, an element that has become common across a number of permit flies. Secondly, the fly's rubber legs are marked with a red marker at the tips, capable of capturing a permit's attention without overdoing it.
10. Danger Muffin
Doug McKnight has tied a number of staple saltwater fly patterns, including the Crimp, Da Tingum, and the Homeslice.
Add the Danger Muffin to the list, as it has taken the permit fishing community by storm. The Danger Muffin's body is super innovative, using a combination of deer hair and rabbit fur. The result is a super lifelike, mottled body that closely resembles the carapace of well-camouflaged crab.
The Danger Muffin uses a combination of chenille and synthetic crab claws to complete an incredibly realistic looking fly--especially when wet. Similar to the Flats Crab, the fly is tied to imitate a crab moving side to side when stripped. If you're heading to The Bahamas, Yucatan, or Belize, this should be a part of your arsenal.
11. Fleeing Crab
Cathy Beck's Fleeing Crab is another tried and true that has been around for quite a while. It is a fairly straightforward pattern to tie, starting with a pinch of brown and tan marabou near the bend of the hook offers plenty of natural movement.
The body of the Fleeing Crab uses synthetic EP Fibers in the merkin-style to create the body, paired with orange-tipped rubber legs. Similar to the original Merkin fly, the small bit of orange at the tips of the legs acts as an attractor. Carrying on tradition, the Fleeing Crab is generally tied with chartreuse thread.
12. Squimp
The Squimp has single-handedly landed hundreds of permit and bonefish in destinations like Ascension Bay. The Squimp is traditionally tied with yellow lead eyes, but works great with beadchain eyes in shallow water situations. A unique attribute, the eyes on the fly are tied closer to the bend of the hook as opposed to next to the kook eye, which serves to keel the fly and keep it level in the water column.
The Squimp is tied with a craft fur tail and wing, with chenille wrapped down the shank. When wet, the Squimp has a slim profile, but the fly's rubber legs offer an abundance of movement and are uncharacteristically tied in on the side. The result is plenty of wiggle when stripped, and feeding fish tend to take notice.
13. Pato's Crab
While Pato’s Crab may resemble a Raghead variant at first glance, seasoned guides in the Yucatán and Belize recognize key differences that set it apart. Originally tied by a local guide in the Ascension Bay area, this pattern quickly earned a spot as a go-to fly among permit guides throughout the region. The most distinguishing feature is the use of brightly colored lead eyes—typically yellow—which not only add weight for a quicker sink rate but also serve as a visual trigger for cruising or tailing fish.
Pato’s Crab is especially popular among Yucatán guides, though its effectiveness extends to permit fisheries around the world. Variations with red, orange, or pink eyes are common, but yellow remains the top choice. Be sure to strip it slowly—too fast and the fly may spin, tipping off wary fish that something isn’t right.
