Smallmouth Bass, Spotted Bass, and Shadow Bass are my three favorite species to catch when fly fishing. I haven't decided if it is because of their voracious fighting ability or the niche in nature they choose to occupy. Which ever it is, even a bad day fishing for them is a wonderful day. One of my favorite flies I use to catch these miniature monsters are my Mudbugs. Mudbugs are the most effective large crawfish patterns I have ever used.

Crawfish are undoubtedly one of the preferred dietary delights of Bass, Walleye, Musky, Trout and other marauding species. They are high in protein and are often abundant in most streams, rivers and lakes. Crawfish are somewhat tolerant of pollution. They can be found in fast moving to stagnant waters, from highlands to lowlands, in bedrock to mud, and occur worldwide---even in grassy pastures during the wet seasons of the year. Crawfish are omnivorous, eating everything that doesn’t move--bacon, dead fish, live fish, dead animals, weeds, grass, etc. Nothing organic is deleted from their diet. All species are physically similar having a head with several antennae and bulging or stalked eyes, a thorax with ten legs ( the forward pair enlarged), a segmented tail section with broad tail fan , and a hard shell over the entire body. They are related to spiders and they molt periodically regenerating lost limbs and a fresh, larger exoskeleton.

Depending upon the time of the year, crayfish range in size from a fraction of an inch to several inches in length. The Longpincered Crayfish, Orconectes longidigitus, is the largest species that I know of. This species inhabits the upland rivers and streams of the White River System in Arkansas and Missouri. The males of this species often grow to lengths of more than ten inches and weight nearly two pounds. As their name suggests, they have extremely long, sharp-pointed pinchers. Rare is the bass or trout that will try to make a meal of one of these large males.

Many crawdads mate in the fall of the year, but the female does not generate the fertilized eggs until the following spring. The eggs are super glued to the under surface of her abdomen and carried there even after hatching. In most species, the young crawfish remain attached to their mother until two molts are accomplished. Then they swim free. Some species grow to adulthood and reproduce in their first year, but the majority reproduces in their second year.

The colors of crawfish differ from drab-- brown, tan, olive, or gray--to brilliant or uniquely vibrant patterns of orange, blue-green, black, yellow, golden, and red. Some are striped, some spotted, some saddled, and still others are freckled. Cave species are nearly white or unpigmented. A few have small pinchers, more have fat pinchers, and all have long, sharp pinchers. Biologists state that predator fish favor the smaller pincered crayfish.

My Mudbugs are tied Clouser style so the hook point rides up. I use large Spirit River I-Balz eyes and six to ten wraps of large lead wire to keep them on the bottom. My favorite tactic is casting the Mudbug near the edge of the bank. I drop my line in the water, and let the current slowly pull the Mudbug along the bottom. Patience is the key to catching the Shadow Bass. They are crevice creatures that will not move far from the bottom during the daylight hours. Shadows, Smallies, and Spots all love crawfish for supper.

What makes this pattern so effective is the clamor created by the large eyes as they bump into the rocks, gravel, and bedrock of the bottom. The clicking sounds get the predator's attention well before the pattern is within striking range. One day in the clear Ozark stream near my home, I watched a Smallie charge a Mudbug from twenty to thirty feet as it came clicking across the rubble rock bottom.

Mudbugs are marvelous in muddy water also. Again the commotion created by the eyes guides the predator to the pattern even though the visibility is reduced. I fish these patterns with a nine foot six inch, seven weight, fast action rod, a Rio Clouser Line, and ten pound Climax Bass Leader---in case I become entangled in debris or snag the bottom. I have created several color combinations and the variations are infinite. For the purpose of the tying instruction we will use my Chocolate Brown Mudbug recipe.

Tying Instructions for Fox’s Mudbugs

I often make one set of pinchers before I start putting together the Mudbug. This gives them time to dry before they are needed for the pattern. I make the pinchers for the next Mudbug while the super glue on the eyes is drying. The pinchers are cut from feathers of a Pheasant Skin. It really doesn’t matter which pheasant feathers are used as long as they both come from the same general area of the skin. Use two neck feathers,

Step 4. Wrap six wraps of the appropriate size lead wire on to the hook shank. This is the body portion of the pattern. Slide the lead down to the hook eye out of the way for the moment.



Step 5. Tie in the appropriate size I-Balz at the base of the pinchers. Be sure to use the suggested size eye or one size larger for the hook that is being used. This will insure the upright stability of the fly. Use a “Xing pattern when securing the eyes. Before super gluing the eyes, move the lead wire up against the eyes and secure in position with several wraps of thread. Remove the pattern from the vise, lay it on a flat surface with the hook point up and adjust the hook so that it is perpendicular to the eyes. Return the pattern to the vise. This little adjustment will insure that the pattern runs hook point up.



Step 6. Super-glue the eyes and lead wire into position. While the super-glue is drying make another set of pinchers for the next Mudbug. I often use two vises and begin another pattern while the first one is drying.



Step 7. Tie in the Sparkle Yarn just behind the lead wire, then wrap the thread to the hook eye.

Step 8. Tie in the tail on the back of the hook at the hook eye. I use the dangling end of the swiss straw that is tied in at the hook bend or a separate piece.



Step 9. Wrap the Sparkle Yarn over the lead wire, around the eyes, the base of the pinchers, then reverse directions and wrap the yarn to the hook eye. Tie off and trim.



Step 10. Wrap the thread forward until just in front of the eyes of the pattern. Rotate the vise so that the hook point is on top. Tie in the four medium strands of Centipede Leg material centered over the eyes. Use a “Xing” pattern to secure the legs making four legs of equal lengths on each side of the hook. The thread should end up just behind the eyes of the pattern.



Step 11. Open the Swiss Straw so that it will cover the back of the pattern completely making the outside shell of the Mudbug. Bring the straw over the back of the pattern place the first wrap of thread over the straw just behind the eyes of the Mudbug. Advance the thread so the second wrap of the thread over the straw is at the end of the lead wire. Then continue wrapping the thread over the straw segmenting the remainder of the body and tail of the Mudbug. Trim the straw off at the hook eye and whip finish between the tail and the hook eye.



Step 12. Open the tail of the Mudbug forming a wide flapper tail. Coat all of the straw with a good coat of glue, don’t forget the tail.



Mudbug Fishing Tips

The I-Balz eyes plus the lead wire on these patterns make them extremely heavy. I suggest a seven weight or larger rod to cast the 1/4-inch eyed patterns. The Rio Clouser Line is a must for handling these patterns with perfection. The 1/4-inch eyed patterns can easily be cast with a spinning rig and the 3/16-inch eyed patterns can be cast with an Ultra-light spinning rig. Spirit River also makes a much heavier, Silver, 5/16-inch I-Balz which I didn't include a pattern for. A Mudbug tied with this eye could easily be cast with any rig.

Mudbugs excel when fished slowly on rocky to gravel bottoms. They rarely hang up, because they rarely invert. In large rocks---larger than a basketball---Mudbugs will climb over these with ease. Patience is the key to fishing them, let them slowly climb up the rocks and fall down the other side. Most strikes are easily detected because they are so violent.

When drifting downstream in moving water try these tactics. Position the canoe or boat so that you are facing upriver, this seems awkward at first---especially in a canoe. If you are in a boat with a motor, don't turn the motor off. Running into a "dead-head" backwards in fast current can be a disaster---the motor will hang up and the boat will barrel-roll as it turns sideways. Hang about two feet of log-chain on three foot of rope from the bow. This slows the canoe and boat slightly in the fast water and keeps them facing upstream. You will find that one person paddling in the back of the canoe can negotiate the most treacherous current with this method. Now that you are facing the correct direction, cast toward the bank behind boulders, logs, and other objects. Don't work the Mudbug; let the drifting boat pull it slowly from behind the object. Let the Mudbug ride the bottom and follow its contour. Your job is to feel every move the Mudbug makes---trying to detect the strike. I have caught three Smallmouth Bass over six pounds---in the Ozarks that's a monster---all were caught using this tactic.

Next, in fast gravel raceways and runs, cast the Mudbug well upstream of the boat and let it ride the gravel bottom. Feel for the strike. The chain banging on the bottom scares the crawfish from their hiding places. They begin to escape from the approaching hullabaloo. When they begin to swim, the current catches them and washes them downstream. The bass will be waiting in the deeper pockets and the drop-off at the end of the run. At the end of the run, move the boat into the eddy on the side of the fast water. Cast up into the current and let the Mudbug ride the bottom over the drop-off several times. I have often caught as many as ten bass from one raceway using this trick. A few bass will be laying at the drop-off; others will come to investigate the sudden rush of crawfish.
