We already mimic them to make fly-fishing lures. But now scientists believe copycatting one tiny insect could hold promise for repairing human tissues and setting bones.
Instead of stitches and screws, doctors may soon call on the next generation of medical adhesives - glues and tape - to patch us up internally.
The inspiration? Caddisflies, a type of stream-dwelling, fish-baiting insects that live in creeks all across the United States.
As a larva, the caddisfly constructs a tiny tube-like house for itself, called a case, entirely underwater, using pebbles and its incredible homespun tape as the mortar.
Thanks to the qualities of this amazing silk, the case not only holds up when submerged, it is strong enough to protect the caddisfly’s soft lower body amid forces many times its body weight.
Any tape, including this one, has two basic components: the flat ribbon, or backing, and the layer of sticky stuff, or the glue. From the materials science standpoint, caddisfly tape is extraordinary in both departments.
Caddisfly silk biomimicry is only in its infancy, but one day, a similar compound might be used inside the body, which is another watery environment, to mend soft tissues and even repair hard ones, such as teeth and bone.
In the streambed, or brook, the caddisfly’s case eventually becomes a cocoon. Like its land-based cousins, the butterflies and moths, from whom it diverged 250 millions years ago, the caddisfly larva undergoes a metamorphosis. It seals up its case with a so-called “hat stone” and emerges months later as a winged adult.
--- Where do caddisflies live?
Caddisflies are most common in shallow, cold, turbulent streams, where the water is highly oxygenated.
--- What do caddisflies eat?
Caddisflies are herbivores, they eat decaying plant matter and algae on the rocks in the streams where they live.
--- What is so special about caddisfly silk?
Engineers are interested in two attributes of caddisfly silk. First of all, it can bond to something, such as a pebble, underwater, which no glue people have made can replicate. Second its “viscoelastic” properties allow to it harmlessly absorb physical forces. When stretched, it doesn’t snap back like a rubber band. It returns to its original shape slowly and safely. It's an engineering marvel.

This is probably the video I was most suprised at... *They make their own armor.* Damn nature...
You scary!
J. DR3SN Have you ever known "nature" to make anything? I find it hard to believe how an abstract noun creates something that the most advanced science of today can't even begin to explain or reproduce.
Haha, good point. Let's just say.. evolution works in admirable ways.
Yep, more like in.. miraculous ways:))
I won't annoy you with my opinion, but think about it: there is no law in nature (no law, no force, no process) that leads something to become more orderly. Nature doesn't organise things, nature only disorganizes things. The more time passes by, the more disorganized they become.
Prove this wrong, if you can!
Why believe that mindless processes - that is, evolution -- can do what brilliant scientists cannot do?
Evolution is nothing more than a theory that is presented as a fact.
If you learn about even the most simple one-cell organism, you will find out it's incredibly, incredibly, incredibly complex... natural laws have never been observed to do that... As an intelligent person, draw your own conclusions, don't accept theories as facts!
Peace!
That's some serious food for thought, I like the way you think.
you made it look as big as a crab. but it's good that you showed it at the end
same I didn't expect it to be that small
+Amber Doesburg ikr
+Amber Doesburg same I also thought the rocks they used were huge but really they were just pebbles
guys, it was a fly... How could it be much bigger than that
I've seen flies much larger than that before
Insect: (*Picks up A Diamond*)
Insect: Wrong rock
that white thing is not a diamond its some kind of rock that looks like crystal sometime
niqsy r/woooosh
*JUST IMAGINE THAT INSECT FOUNDED A SHARRERD DIAMOND AND JUST THREW IT AWAY-*
niqsy wooosh
we get it he missed the joke and its woosh with 4 Os
"something that has eluded us humans...tape that stays sticky underwater"
Can I convince you by sawing this boat in half?
Nice zeppeli
NOW THATS ALOT OF DAMAGE
lol
Now we know where Flextape got their idea from. Hehe
IT EVEN WORKS ... UNDERWATER !!!
I'LL TAKE YOUR ENTIRE STOCK !!!
I did not realise they were so tiny😱
Realize (z)
soo same
That's wat I was thinking when they showed the video I was like oh these things are quiet large then bam it was like the size of less then a small ant
@@emomc9557
It's different from British and American spelling
depends on the species of caddis there are a lot of them, and they don't all use pebbles, some use plant matter others just their silk alone.
as far as insects go, these ones are pretty cute and non-horrible
I stand that.
iono....front half reminds me of a spider.
When you are familiar with rats, they can be cute, too.
I remember seeing somewhere that there are people putting these insects in artificial environment with little rocks of gold or gems instead of the little rocks these insects make their "repair". The insects make their things and these people sell the "repair" those insects have created as jewellery especially earrings. I hope that doesnt damages the animal.
(Sorry for my eng)
I've read about people who keep caddisfiy larvae in tanks filled with gems and the cases look amazing
woah

I do haha
Level 1: Silk cocoons
Level 100: *Cobblestone armour*
EchO Lvl 9999: Gold and pearl armor
Ilya Chap lvl ????? *air armor* BUT UNDERWATER
Lvl 999999999999 Diamond armour
Cobblestone armor gives me Minecraft vibes
Being honest, this is one of the best edited channels on TH-cam that i ever seen, excelent work. . .
Thank you, Carlos.
Wow.. I'd never before heard of that little bugger.
Neither have I.
I've heard of it, but didn't learn much about it.
grammar plz
when I was a kid I used to catch a lot of these things in the river, but these insects are very sensitive to water quality
*****
Ah, that's probably why I never saw one. The creek behind my grandmother's house has a sewer pipe that dumps sudsy water into it.. and further downstream a small oil refinery ran a pipe to it. They claimed they were just sucking creek water into the plant, but the water is has that telltale rainbow tinge on the surface. The EPA never did anything about either.
You saying this bug makes NATURAL FLEX SEAL!?!
... and It even works underwater!!!
@@ukaszmuszynski448 r/flexseal
With a tool that has eluded humans, tape that stays sticky underwater...
HI PHIL SWIFT HERE FOR FLEX TAPE, the easiest way to patch, protect, seal and repair! IT EVEN WORKS UNDERWATER!
Lol
CUT, PEEL, STICK AND SEAL
NOW THAT’S ALOT OF DAMAGE
caddisfly larva: *ILL TAKE YOUR ENTIRE STOCK*
Whoever does the audio background noises is very talented. I love the subtle bug crawl noises, the gentle sound of water flowing, etc. Love these series of videos. Great work!
:0
Jesus Christ!
Those sounds will most likely annoy you after watching your seventh video with them. Afterwards, you might prefer muting them, turning on your own music, and reading the subtitles instead.
@@richardbonnette490 Your preferences and likes* don't and shouldn't apply to anyone else.
Caddisfly larvae are so awesome!
I've been researching Caddisflies for a Biomimicry class assignment and learned that in addition to shape and size, they are also selecting for texture. Caddisflies need a smooth interior shell to circulate oxygen for respiration inside the case, so the smoother the stones, the less silk required to adhere the case pieces together. If they have to build with rough surface textures, they do, but it requires coating the entire inside with more layers of silk to make it smooth. So in addition to being very skillful builders, they are also incredibly efficient in their building process.
Thanks for this video - they are kind of cute too :D
That's super interesting! Thanks for commenting!
Nice research on this!
As close to a Rock/Bug type Pokemon in real life as we're gonna get and I LOVE IT!
Its literally Dwebble.
Wow, thats some Tech on the larva. They are great builders
Yeah you wouldn't expect some insect so small to be so clever
kinda cute in a way
Adorable.
Like you.
Pikapetey Animations Wow, I love you weird to see you here. thanks Creator deep look.
Pikapetey Animations never knew you'd whatch these
pikapetey what are youuu doing here
I couldn't do this. A fly larva is smarter than me...
My Art Page it’s not in the fly family
If you could spew tape from your mouth you might. Lol
For you, it'd be a passing fancy. For the larva, it's survival.
I love the music, the 'small worlds', your voice Amy... and the warm kid-like happiness I feel watching your videos guys. Thank you!
I love showing these to kids when I teach. There is actual jewelery made from these guys.
1. This is amazing, never heard of them.
2. Now I wonder how many I have accidental killed when hiking down a river. :(
3. Do they bite?
Also for the slightly more cruel, if you pop them out of their armor, they make for excellent fish bait.
even nature cosplays. AYEEE
Heh, true.
Deep Look you should do something for deaths watch beetles
um...thats hisoka....it is useing bungee gum right?
What character is that?
It kind of reminds me of the Pokémon Crustle
They're so tiiiiiiiiiiiny! 💙 Let's protect them please..

Thank you #DeepLook 💛 Your videos are AAAAMAZZZZIIINNGGGGGG! 💚
That's truly incredible how small these creatures are. It puts us on their perspective. I am a big fan of this channel! 💜🐛
When they find the stones, it's like me trying to find the right lego brick.
Exactly!
Me lol
I dunno why, but watching it try and select the perfect stone was incredibly cute
All fine craftsmen need the perfect materials.
I like how it yeets the stones it doesn't like
Brilliant, things like this makes me appreciate more the world and nature.
Caddis "phil swift" fly:
Now those currents cause A LOT OF DAMAGE
But thanks to caddistape you can build a shelter
IT EVEN WORKS UNDERWATER!!!
XDDDD
This is beautiful. Thank you for existing.
Thank you for watching!
+Deep Look there is a new species of bat in Gibraltar I live there it was on the chronicles maybe you could do a video about it :3
Wow, I really have to say that you guys make amazing videos. I have never even put much thought into what the larva of the caddisfly must be like, and low and behold it's a an amazing work of nature. Wow. I can also say I am just as amazed when it comes to the time it must take to actually film and edit all of this, haha.
I would love to one day see you guys do a video on pitcher plants, there are some amazing ones. Like the Cobra Lily!
Take care!
I've forgotten that I've been subbed to for years now. What happened? no videos in 7 months.
Crux College and life.
I have been working on a very big video, will be would tomorrow if all goes well actually. Vsauce will have a small part in it too. ;)
Thanks for the kudos and the great idea!
that's a great idea
“Fly fishing lures mimic the caddis fly adults in pain-staking detail.”
*shows side-by-side of a caddis fly and a hook wrapped in string*
th-cam.com/video/NdLpOwNQ2Uc/w-d-xo.html i thought the same till i seen this.
I'm an aquatic ecologist specializing in stream restoration and I'm going to start showing this to my trainees. Amazing work Deep Look!
I started crying... this guy is so lovely, it's amazing
Whaaaa? What made u so emotional bout it?
@@losimkimrey6531 probably on shrooms
When an animal plays lego better than you.
And Tetris!
Well made documentary. It caught and kept my attention.
Wow, Deep Look folks, y'all never cease to amaze me. Thank you.
Please Deep Look! Show us how do crickets sing in slo mo!!! I've been looking for that for so long and seems like nobody else has thought in that.
Great idea! Thanks for sharing.
Greate video.. Thank you..!!!
Just think, that little bug knows how to build itself an armored shell, along with all the other knowledge a bug has. I find it hard to believe that such a little brain is able to make what looks like a really well-designed structure. Just think of what that means for the potential of robots.
I think its more to do with instinct than them processing information. Like how our hands jerks itelf out if it touches something hot - we do it instinctivly. At least thats what I think.
Humans have always got down the reproduction part. It's just liberals who forgot how to have kids.
gmusashi45 - It's an interesting thing to think about either way though, so many different creatures that are not intelligent have incredibly complex behaviours that you can't help but see the intelligence in.
Decarabia Jo - Jeez, is there a comment section anywhere without one of you RWNJs spouting your BS? Grow up.
Decarabia Jo - He's talking about how we can build life-like robots but nobody has created a robot that can reproduce. No need to propagate hate wherever you go, just because you're confused and angry.
Thanks but I already got the comment.
I’ve lived on this planet for almost 70 years and still get blown away by stuff like this. I had never even heard of a caddisfly. Nature is truly so amazing.
OMG totally blew my mind at the end when you revealed their actual size. I thought they were the size of large caterpillars or perhaps the size of my thumb. I had no idea they were so tiny. Truly amazing.
Could this be something of use for people with collagen disorders? Ehlers-Danlos syndrome for instance. I'm just wondering because I have this illness, and my "tape" is so faulty that I have joint dislocations and subluxations every day, and pain constantly. I'm 20 years old and feel like an 80 year old. My body produces faulty collagen, but perhaps this little creature might hold the key to a new treatment option?
Extremely interesting!!
I can't even imagine the trouble you all must go through to get these amazing footage. Great work as always.
So unbelievably cool. Absolutely my new favorite bug.
Loved this channel for years. Great work.
deep look has the quality production of a channel with a million subscribers and then you look at their subscriber count and are astonished...
love your content
We'll get there, we hope! In the meantime enjoy and share our videos!
I truly hope you will. You're truly deserving. You illustrated so many things I've been learning and never really had an opportunity to see, certainly not in the glory of all these details and action.
Good luck to you, though I'm sure you won't need too much of it, If you keep up the good work like this ;)
This content is too good for TH-cam
I’m literally speechless! Nature is just so amazing
In my recommended and, wow, so glad I watched. Narrator's voice is nice and content is amazing. Color me subscribed!!
What do you guys use to add the foley sound effects? They sound really cool and somewhat unnerving!
So cool, good job, it really makes it feel like you are really close to the bug.
Wiggle wiggle wiggle woo
i have watched 298457439856 hours of nature videos and have never seen this...as someone that works on adhesion for a living i could not be more mind blown...an underwater adhesive with 200% ELONGATION that slowly retracts???? are you kidding me? PBS you have another subscriber.
Nature is so amazing.
so cute choosing the pebbles
I just love this channel!!!!
Yes. glad you showed it at the end. couldn't tell how big it was. another great video.
yes! finnaly someone is talking about the caddisfly!
Oh my God, I love this Deep Look series 🤘🏿❤!
I love it that we always will keep going forward; searching for discovering and so on forever!
This is one of the best channels I've seen!It's not just the content but also your commentary!keep up the good work!!
Awesome! Glad you like us!
Great films, amazing narration, nice music background. definitely subscribe! thank you very much Deep Look.
Welcome! We're so happy to bring these videos to you.
I appreciate your work, Deep Look. Just after seeing your video on crickets, I was wondering how dedicated you are to your work that you could zoom in so close to small things. Thank you very much.
I used to find these guys all the time in the creek that passed through our property. They're neat!
These videos inspire me so much! The Editing is great, The Subject is very interesting, And the research is extensive! I'm so glad things like this are at our grasp. Keep it up guys!
Many thanks!
Everything about this video is awesome!!! Thanks!
As I am already subscribed, I liked and shared this video and I can't wait for your next one!
Thanks so much for sharing! We appreciate it!
The way he throws the rock that unmatch, " Too Big", "Too SMAAL", "NOOOO fu** *throws the rock* LOL (see at 2:10)
So amazing! Who would have guessed such a marble was in our world? Neat-o!
I thought they were hand sized and they were normal sized pebbles 😂 they're tiny!!!
Such a high quality video. Good job! I actually learned something from these videos. Also, I love how the narrator explains things as if we're seeing it with our own eyes. :)
Thank you!
you deserve more subs!
I was so happy to find hundred of them in the rivers this summer in Drôme, France. They are amazing!
These guys are such cute little critters, I love them.
You guys need more exposure! This is just hypnotizing...
Thanks! Please share and help us grow!
11pm: "I'm gonna sleep earlier today"
2:25am: "THIS BUG BUILDS AN ARMOR OF PEBBLES USING MAGIC UNDERWATER DUCT TAPE FROM IT'S CHIN"
I like this part 2:11 the way he throw the pebbles are adorable.
Watching it build its shelter was adorable tbh
I'd love to hear about the evolution of these little critters. I'm so interested in how they arrived at this behavior. Another great video with top notch production value!
- Cheers
Amazing little animal! Thank you for this deep look!
Thank you! Wonderful look at the Caddisfly.

Thank you FlexTape!
It is such an amazing little creature and I've never heard of it!
Amazing work guys just wow!
This larva is so ingenious. We have a lot to learn from animals and nature itself.
I simply love this channel.
This is so cool. Subscribed!!
Thank you and welcome!
Just find this great channel, really like your content!
Thank you! We hope you like all our videos!
If only other animals were this creative
Camouflage and armor at the same time! hardcore!
"Like how to survive in a hurricane."
You dare leave this in my recommended right after hurricane Harvey passed through. How could you
i JUST discovered this channel :) & i love it lol.. thanks for awesome videos
Thank you for watching!
Wooooooowww!!!!! Thank you a bunch for all the work you guys do to bring us these videos
That is so flipping cool!!! Bugs that build houses! Way better camouflage than hermit crabs too. Then when you showed the actual SIZE, I couldn’t believe how tiny they were!
Great macro camera work, just outstanding. I seriously thought they looked as big as beetle grubs.
Another intelligent animal.
WOW... so fascinating!
Thank you, Laynie.
I LOVE THIS CHANNEL!
You guys should do an episode on one of the thousands of common aquarium species/genera (if you haven’t already)... tons of them have amazing life cycles. Would be so fun to see with your style of cinematography
Tape that stays sticky underwater, eh? Well, I got someone for you to meet.
*-Phil Swift kicks the door down*
Fix bones you say?!? No my friend, I too will build waterproof armor and tussle with sharks!
We would definitely pay to see that.
Thank you Deeplook
I used to see a few of these while scuba diving. They're so cool; their behavior is like a strange mix between a spider and a hermit crab.
It's interesting to me how so many arthropods seem to be more meticulous than the average vertebrate. These larvae are so intellectually basic, but having 6 grippy and disproportionately strong legs are a pretty easy way to manipulate objects.
This is FANTASTIC! Cant wait to share it with my fifth graders!
Awesome! Let us know what they think!
I love it nice video got me to subscribe after the second vid 👍🏽👍🏽 also something I really never do hitting the notification hope to see more great stuff
When I found my first caddisfly larvae as a kid, I was so enamored by the casing....and then the larva began to crawl out and it looked straight out of an alien film! XD
