Here is a fishing lure so revolutionary it allows spinner fishermen to "match the hatch." From its fluttering, veined, lifelike wing to its expertly finished segmented body, the Mepps Thunder Bug looks like a bug, acts like a bug, and, to panfish and trout, is every bit as tasty as a bug.

Computer age finishes to resist chipping and peeling. Your choice of dressed or plain ultra sharp, strong treble or single hook. Mepps unsurpassed quality. Mepps Thunder Bugs... bugs, so natural, we've even given them bug names.

Thunder Bugs, the lures, not the bug, are available in size #00 through #2 making them perfect for both panfish and all sizes of stream trout. The size #2 Thunder Bug is also great for smallmouth bass and walleye.

Whether you choose to use plain or dressed Thunder Bugs is strictly a personal preference. Lure size, however, is important. The rule of thumb is use smaller lures to catch smaller fish and larger lures to catch larger fish.



The image you see behind the lure is a picture of the actual sound waves created by that particular lure.

Thunder Bug #2

Waveforms of the sounds produced by the Thunder Bug #2

When Mepps developed the Thunder Bug it was introduced as the first and only spinner that allowed fishermen to "Match the Hatch." Not only is its blade shaped like a bug's wing, it is veined like the wing of a bug. Its body is segmented like the body of a bug. These lures also come in color patterns imitating insects. In fact, they look so much like insects we've given them bug names, everything from grasshopper to white miller to stone fly. . . nine different patterns, too, will match the hatch. However, what we didn't know until now is a spinning Thunder Bug blade SOUNDS like a bug. That's right, a Thunder Bug pulled through the water produces a sound very similar to small rapidly flapping wings. We also discovered, if we increased the speed of this file about 3 times and raised its pitch, the sound became a buzz. While this is hardly a scientific study with any definite conclusions, listening to this enhanced file can be fun.

The Cricket Thunderbug is one of the very best bluegill lures I've ever used. This is not surprising, since crickets are known as a great bluegill bait. I've caught maybe hundreds of bluegills on the Thunderbug in many lakes in Northeast Kansas. Lake Lenexa is a small flood control lake with very clear water for a Kansas lake. The darker color of the cricket Thunderbug is perfect for clearer water.

Fish Caught: Trout, Brown

I have caught and landed many awesome trout using Mepps lures. A very memorable 6lb brown trout that I caught, landed & released using a white Mepps Thunder Bug. This has thankfully given me memories that will never get away. I use all of the colours of the Thunder Bug range though out the year & here in New Zealand we are lucky that most of our streams, rivers & lakes allow us to use these lures. For me being new to the sport of fishing, the Mepps Thunder Bugs allow me to match the hatch like a pro & still command the respect from even the most staunch fly fisherman because of the way my fish go back into the water after they were caught on a Mepps...... LOVE MY FISHING.....LOVE MY MEPPS.

Dilly Vue – Taku Lake, Alaska

Fish Caught: Trout, Rainbow

This was my first spinner I ever got....
When cast it is very light, but, no matter
you can still get 'em from short distances.

When I use salmon eggs or any live bait
nothing seems to hit, even worms.

I caught 5 smallmouth trout and 5 bigmouth trout
Everyone in facebook thinks I'm snagging, but this Thunder Bug gets me everywhere....I use size 0. :)

Fish Caught: Bass, Largemouth - Bass, Smallmouth - Trout, Rainbow

This lure works perfectly in shallow streams and rivers where the current is fast and the water is clear. The fish can't resist going for this lure, it never fails. When the scent baits aren't working just pull out The Thunder Bug and watch the magic happen. This lure is a must for any species of trout; the #00 works the best in all silver.

Mark Jones – Helton Creek, North Carolina

Fish Caught: Trout, Brown

These lures make up 90% of my spinning collection. These are fantastic lures that consistently provide quality/quantity. Routinely produce takes of fish 17"+ which are consider trophy size trout in this part of the country. Mixing weather conditions and times of year with these lures will produce results that typically out fish everyone else on the creek. The only bug I've not produced with is the firefly. I would love to see a damsel fly version of this with blue wings white body hint hint lol. If you never purchased one of the bugs do yourself a favor and add one to your next order.

At last, woke up to the sound of much needed rain and very humid conditions, some thing that I have been waiting for quite some time. After a nice bacon,eggs, mushrooms and grilled tomato breakfast that the local bakery put on for me this morning for my Birthday, then it was off to the Mersey River at Kimberley for a spin fishing session.
When I arrived it was a matter of waiting for around ten minutes while a thunder storm passed over and the rain eased off to a light drizzle. By the time I had put my waders on and set off the drizzle was gone and then the humidity really increased as the sun decided to poke it head through the clouds. This wasn't what I wanted at all, as it was supposed to stay overcast. After a 100 mtr walk to the river the clouds had covered the sun and it was back to perfect conditions for fishing once again. Started of with a Mepps # 00March Brown Bug spinner that had worked well on the Meander River last week, and I couldn't see why it would not work here either. After covering the first section of river all I could manage was a couple of follows from some small browns. This was the same over the next couple of hundred meters only difference was that I couldn't even get a follow, so it was going to be a tough day from my reckoning. Is it going to be one of those days I thought to myself, I hope not!
There was not a breathe of wind here and the long slow stretches of river were like glass with only a few rippled circles on them from small fish jumping from time to time. Seeing fish jumping is not what I wanted as when they're doing that they normally won't take a spinner. Hell it was hot on the water, and the perspiration from my forehead was causing the polaroids to mist up making it like I was fishing in thick fog. This was not how the plan was supposed to be going at all!! Decided to bypass the slower sections of river and just hit the fast water sections of the Mersey. Trouble was this area I came to didn't have that many fast water sections to it, so I only was limited to a few sections of river. Well that will just have to do as I wasn't walking back to the ''Trout Stalker 2'' and then driving some 10 kms to another area to fish as I was already hot and a little ticked off. So I'll just have to stay here and put up with it and get on with the job in hand and that's ''catch some fish.'' I'd be happy just having a hit and miss for now.
On my way to a small fast run I decided to change my spinner, and it was too be a # 00 Black Stonefly Bug this time and it worked a treat too. This small run wasn't very wide so I could work it from the river bank in which I did. Casting across the river and into a small calm piece of water on the opposite bank that had some cover from tea trees I picked up a nice fat little brown that tipped the scales at 275 gms. A quick photo and then it was released, and boy it was good to finally get a hook up when it was looking like being a day of zero's.
The next fast water was one that I have always picked up a couple of rainbows or at least a brown so I was pretty confident of adding to my tally there. After covering every part of this water all I could manage was two hit and misses, not what I was expecting at all. So it was on to the next section of fast water and this proved to be much better as I did pick up a nice plump rainbow (310 gms released) and hooked and lost three browns. So this run did prove worth while, and not before time too. The next run of fast water was around 600 � 700 mtrs further upstream and I was too hot and bothered to go all the way up there to give it a spin, so decided to make my way back to the ''Trout Stalker 2'' some 1.5 kms away. Halfway back the sun broke through and it was a wise decision in the end as well, probably the smartest one that I had made all day. The Mersey River is still very slippery and this really makes it tough going most times, and it does take it's toll on the body after a few hours in it. Or is it just me ??

River: Mersey.. Browns: 1 (275 gm released) Rainbows: 1 (310 gms released)

** Both fish caught and released were taken on a '' Mepps Thunder Bug Spinner '' **

Adrian Webb – Meander River, Meander. Tasmania Australia

Fish Caught: Trout, Brown


Could not have asked for a better start to a spin session in the Meander River this afternoon in warm and sunny conditions. Clear water and a light Nth Easterly once again didn't stop me having a great start as I hooked and landed a small brown on the first cast into a fast water section. This little fish took the gold beaded black nymph that I had as my drop fly today. There were quite a lot of dragon flies about today so I was equipped with a #00 March Brown spinner set up below the anti-kink once again, as this spinner worked reasonably well here on the last trip. Seeing it was going to remain bright and sunny for some time I decided once again to stick with the fast water stretches of the Meander. This time of year when the weather has warmed up considerably and so too has the rivers, the trout will be found in these stretches of river. It's always a little cooler plus the water has more oxygen in it, where as the long slow flowing sections are the opposite. The long slow sections are better fished at first light when the water has cooled over night, or on dusk when the sun is not on the water. I would prefer the morning out of the two.
The next area of fast water gave up two more small browns from three hook ups, so it was looking like I was in for a very good session, hoping for a catch of at least 20 plus fish by days end. Onwards I went working my way up and into the fast water not missing even the smallest bit of water that I though would and should be holding fish. Three trout taken in a row, a hat trick of trout some thing I haven't done for quite a while now, and that 20 plus was looking good. With the sun now a little lower in the sky there was more shaded areas on the river now which was great, as not only was it better for fishing it was nice to get into it and cool of a little. The shade was covering around a third of the river so I just kept working those areas of it and finished up landing another seven browns from nine hook ups.
Over the last 600 meters of the Meander that I fished all I could manage was two hit and misses and they were the only two fish that I came across. What a fizzer this last stretch of fast water it was! To make it worse was the fact that this last stretch has always been the best to fish as it has always given up a number of fish. So what was a great start to the session early certainly didn't finish that way in the end and the 20 plus went right out the door.. but hey! That's fishing isn't it.
The best fish went 290 gms the rest of them averaged 260 gms. The Meander is really holding a large amount of small fish this season, as last season fish were averaging 360 gms plus. Rainbow trout have been few and far between too as I have only caught one so far. I feel that when the Huntsman's Lake turbine broke down last season in March causing the river level to drop so low, then with the influx of many flocks of cormorants on the river and its tributaries took its toll on the whole system.
cheers Adrian
