Because it's hoarding protein. Not just for itself, but for the butterfly it will become and every egg that butterfly will lay. And it's about to lose its mouth... as it wriggles out of its skin during metamorphosis.

That caterpillar in your backyard is chewing through your best leaves for a good reason.
“Caterpillars have to store up incredible reserves of proteins,” said Carol Boggs, an ecologist at the University of South Carolina. “Nectar doesn’t have much protein. Most of the protein that goes to making eggs has to come from larval feeding.”
Caterpillars are the larval stage of a butterfly. Their complete transformation to pupa and then to butterfly is a strategy called holometaboly. Humans are in the minority among animals in that we don’t go through these very distinct, almost separate, lives. We start out as a smaller version of ourselves and grow bigger.
But from an evolutionary point of view, the way butterflies transform make sense.
“You have a larva that is an eating machine,” said Boggs. “It’s very well-suited to that. Then you’re turning it into a reproduction machine, the butterfly.”
Once it becomes a butterfly it will lose its mouth, grow a straw in its place and go on a liquid diet of sugary nectar and rotten fruit juices. Its main job will be to mate and lay eggs. Those eggs started to develop while it was a pupa, using protein that the caterpillar stored by gorging on leaves. We think of leaves as carbohydrates, but the nitrogen they contain makes them more than one quarter protein, said Boggs.
-- What are the stages of a butterfly?
Insects such as butterflies undergo a complete transformation, referred to by scientists as holometaboly. A holometabolous insect has a morphology in the juvenile state which is different from that in the adult and which undergoes a period of reorganization between the two, said Boggs. The four life stages are egg, larva (caterpillar), pupa (also known as chrysalis) and butterfly.
-- What if humans developed like butterflies?
“We’d go into a quiescent period when we developed different kind of eating organs and sensory organs,” said Boggs. “It would be as if we went into a pupa and developed straws as mouths and developed more elaborate morphology for smelling and developed wings. It brings up science fiction images.”

Amazing! Now I know why Bear Grylls is always talking about a caterpillars protein content, when he's looking for breakfast! 😝
Thanks! See our previous video on palm weevils if entomophagy interests you.
Deep Look What're you talking about? I've seen all your videos... They never slide past me. ❤
but not all caterpillars are edible, do they? since some have toxic.
Yes ,specially the bright colored ones.
Mak Shethiya he's a cheat cuz when he is off camera he goes to the closest 5 star. Hotel and gets buffets there

Isn't that what acne feels like?
@@TheIceCreamWizard ???
William Gabriel Gamboa that weirdo's name
Fun fact: studies have been done that indicate butterflies actually _remember_ being caterpillars. Long story short, scientists exposed caterpillars to a shock every time they smelled a certain chemical, and then after they emerged as butterflies they reacted negatively to the same scent, expecting to be shocked.
That could just be them remembering the negative experience/pain, not necessarily remembering being caterpillars
I’ve heard of this before too! It’s kind of like, if you emotionally attached to something as a child, you can see it as an adult and it will bring up many memories!
Oh yeah? Got any sources?
Luis Castellon umm I don’t know where but I think if you just search butterfly shock experiment, you might find it?
I guess not for BEING A CATERPILLAR but from the experience they've been exposed to.
It is also connected to a study of a child experience that brings out "Phobia", some are horrible experiences from their childhood that lead them afraid of a minor thing even they are grown up.
Those caterpillars make leaves look tasty...
TorTorTalks that sounds like something a caterpillar would say
TorTorTalks they do look tasty

Chrysalis... not a cocoon.
If caterpillars can achieve this kind of glow-up, then there's hope for all of us.
there's no hope for me.
**and by eating so much

Same tho ;-;
Imagine you were just born and you start eating the hospital bed and you’re like: “Hey that’s pretty good.”
I was left speechless, i had no idea caterpillars shed their skin when they go through metamorphosis. I thought they built the chrysalis around their body. That's so cool. I wish I was taught that in school.
Depends whether it is a moth or butterfly caterpillar. All butterfly (and some moth) caterpillars molt into a chrysalis form as in the vid while most moth caterpillars spin a cocoon with their silk.
Jacob Terrell Man your profile pic made me think that there was a hair on my screen
Some species do that, but the others basically has their skin hardens, and some sorta chemical digests them in a way and that mush builds the butterfly. Summary, skin hardens, caterpillar turns to mush, and that mush builds a butterfly.
too much pokemon
At my school, we were taught that caterpillars have 3 forms, Caterpie, Metapod, and Butterfree.
The Caterpie turns into a Metapod by leveling up. The Metapod turns into Butterfree by waiting a few battles. The Butterfree is now a level 17 adult.
If it is female, we put it in a daycare and use a Ditto to breed it. If it's a male, we leave it inside the box until one of us dies.
A caterpillar eating up close is so satisfying to me.
I love how caterpillars are just chillin and eating
Arion perfect spirit animals
Just wait for wasp to zombify them😂

Caterpillars will always hold a special place in my heart. When I was little I would go look for monarch caterpillars on milkweed and put them in jars so I could take care of them. I love watching them grow and change from caterpillars to butterflies.
so like, they can evolve into butterflies inside a jar?
@@KCrispyINDO they probably had a bigger area where they would put milkweed leaves for them to eat, or just put milkweed in the jar
I did that with vine hawkmoths. I have to cut some leaves of the caladium plants or ask some neighbors for leaves.
@@KCrispyINDO At first yes, I would raise them in jars with holes or mesh added to the lids. I would also add some sticks for them to crawl on along with milkweed to eat. Later I got one of those bug encousure things which made things easier
“Mammals like us are weird ones.”
Couldn’t be further from the truth.
Monarch are always on our leaves in my front and back garden
*Yay*
Creeper? aw man.
I also love how you include the discarded empty husk of the caterpillar. Usual documentaries always skips them, I wonder why?
LagiNaLangAko23 Is it any gross and grisly than snake shedding its skin? I mean it also has a face, and the detail... I watched those skin changing snake documentaries just fine when I was 5.
Hmm, I do think they should have show the caterpillar husk. So that overly curious children (like I was) wouldn't pester their parents about that.
My parents pulled answer out of their butts that caterpillar's skin and body get reassorbed for the butterfly. That's actually creepier than saying the outer skin just fell off.
Until literally a minute ago, i thought they just built their cocoons, shows how much my school did not teach me

I think there's a gif on Facebook that shows a closeup of a shedding snake's face. It's the weirdest thing ever, it looks as if the snake is spitting itself out of itself, so bizarre.
"We are the weird ones".. I stopped for a second and I was mind blown because it was true!
Rico well, other animals didnt invent nuclear weapons so, i guess its true

And till date I used to think that Caterpillars make a cocoon around them from silk like kind of thing that spiders do with webs
Some do that though.. for example silk worms😅
It seems that it's mostly moths rather than butterflies that make silk cocoons. Silk worms are a type of moth.
Chaitanya Singh I thought there was eyelash on my screen. You be conned me with that profile pic
Even though moth caterpillars make cocoons, they still shed their skins and form a chrysalis inside.
Only just discovered this channel. ..loving it
I love how talented the narrator is.. she makes it so interesting. Even the video obviously. Good job lawrence and the other team
Am I the only one who thinks caterpillars are actually cute?
You most certainly are not!
I always try to raise eggs I find in the wild and I can tell you that caterpillars are objectively cute.
I hand rear wild Monarchs to aid in the survival of the species and I love the caterpillars.
Awarne Gaming Yep Kinda cute.
Awarne Gaming I think they are one of the cutest insects on the planet.
Okay I think we can all agree that caterpillars are the cutest, like look at 1:37, they literally look like they have built-in shoes for feet
I have a friend who is learning about animals or something, I can't remember what exactly, but she have had shown on snapchat little clips of all the little insects and marine animals she encounter in class. She made me become fascinated with caterpillars.
When I saw those little legs I shrieked from cuteness

Nope! Painted lady caterpillars are horrifying
The woolly bear is a moth larva... and it's cute.

Many thanks!
The Artian why does your comment seem SO sarcastic
no really why?
thank you that's better

Trust me I'm not, I genuinely love this channel
maybe cause of the "not boring to watch", that was unnecessary xD
Amazing footage you guys have filmed😜 Thank you!
I love the way Lauren narrates the life of a caterpillar ❤
Always amaze me how you guys can get macro shots this close without scaring away the critters. A real feast to the eyes!
LagiNaLangAko23 Yeah but Butterflies? They fly like butter.
YoungTheFish
I'd imagine they have a zoom lens.
Paid actors and actresses
To be fair monarch caterpillars are pretty brave, or maybe they're just too busy eating!
This is actually the first video on caterpillers I've seen that mentioned that they shed their skin to make their Chysalis. Did not know that. Other videos and shows always seemed to imply that they used their silk for the chysalis. I wonder why? Anyway, great video as always, I love your content! :]
They use the silk for the cocoons, which are the casing outside the chrysalis/pupa. If it's a silk worm, it spins a cocoon the pupa goes inside. Pretty much cocoons are different from chrysalids, and only some caterpillars (silk worms mainly) make them.
If you think,if it Does make it. Shouldn't it begin with the tail? Yet the chrysalis appears on its head.
Chysalis? Please explain to me what that is. If you meant to spell *chrysalis* then you can always edit it and make me look like the fool and not you.
@@paigeswan7768 what did he do to you? Geez, that's why people are getting annoyed by grammar/spelling hippies. Acting all superior even though the other person didn't do anything, then starting an argument. Don't push it kid.
That’s so fascinating thank you!
Amazing! Thanks for the info.
I love the fact that the caterpillar eats the entire leaf, leaving no waste. I'm ok sharing my garden with conscientious critters like that!

wait its pronounced antenee? I've always said antenay
Leon Leee I've always said "an-ten-nuh"
Well guess im in the gray area cus I say it as an-tae-nah
The Warden I think they're referring to it being plural. You know like goose, geese. Antenna, Antennae
actually the plural of antenna is antennae because it is a latin word.
ive always pronounced it a-tun-noh
yes yes i am caterpillar yes yes yes nom nom nom
I love this channel! A new world
Butterflies are such beautiful creatures. It’s really amazing when you get to watch the process yourself. I did just that in third grade and it was so interesting to see.
I wish people would appreciate this type of video
You can't really tell the limit of work for this 5 minutes video
Just wawo amazing
Great video as always! I wonder how you film those extreme closeups with absolutely no shake.

am I the only one that finds the music in these videos amazing? I just keep going back 10 seconds because I want to listen to it but then I don't know what the narrator is saying. Amazing channel!!!
Thank you, Juan. The music for Deep Look is composed for each video by Seth Samuel. Hi music is an integral part of what makes Deep look special. We are very lucky!
That's a very intricate sight into the butterfly's cycle. Thanks Deep Look!
1:20 *WHAT!? IS THAT THE CATERPILLAR I SAW ON THE TREE AT MY SCHOOL YEARS BACK!?* Nice!
I love such high quality documentaries
Working at an invertebrate zoo as one of their educators, this video was wonderful as it was much more accurate than most other depictions, and still cringeworthy with misconceptions.
The outside of the butterfly’s body during the pupal stage is not “protecting the pupa inside,” the entire thing is the pupa.
For a butterfly, their pupa stage just has a fancy name: the chrysalis. Originating from Greek meaning golden house. And the term pupa or chrysalis can be used interchangeably for butterflies. Not that one is inside the other. Just how a butterfly’s larva is called a caterpillar or a larva.
The outside of a butterfly as a pupa/chrysalis is similar to the larval stage or adult (imago) in that it’s the animal’s exoskeleton.
Hey, I'm watching your videos, so cool ! One of the best biology channels I ever seen! 😃
I worked with Pipevine Swallowtail caterpillars in a research lab in college. Those first-instar guys are so tiny! The camerawork you guys do is really incredible.
I am addicted to your channel after watching one video...

Monarch caterpillars are just the cutest sweethearts, I've found a few before and they just crawl right up on your hand and hang out! Love em
Them and the earthworms are the 2 "worm-like" creatures that I absolutely dont mind holding and let them crawl on my arm, otherwise if its any other worm I would freakout, feel like vomiting, and get mental visions of parasites.
im learning so much from this video
Caterpillar feet are so cute for some reason....
I want more videos of butterflies, it's so satisfying to watch them hatch ahahah
I love your channel guys🙂

Hi Lauren.. I have a correction here.. The shedding of caterpillar skin to chrysalis actually just take place within 24 hours after they do the J-hook. Other than that this video is realllllly amazing!!! I currently have some monarchs in puppa stage right now.. I love them!!!

I love how the caterpillars start thinking for their children when they are born
"our face doesn't fall off when we grow up..."
believe me it does!
When I grew up, my child body turned hard and then my adult body ripped straight out from the belly out. Here I am now as an adult.
I'm rearing eight eastern black swallowtails (Papilio polyxenes) that just entered chrysalis! The six that attached to twigs are a brownish hue while the two that managed to climb up the glass walls of the vivarium are bright green. I have no idea if that's just a coincidence or some kind of strategy I wasn't aware of? Anyway, it's a beautiful and fascinating process. It also makes you feel kinda like you're doing something good; I'm not sure the eight I plucked from the dill in our herb garden would have reached adulthood without intervention. P. polyxenes is common, but those who rear monarchs do the world a favor: the population has dramatically declined in the past few decades and extinction is a real threat. Stock up on milkweed if you can...
I’m scared of butterflies I think I’ll stick with caterpillars
I'm a cat, I eat both.
You r amazing seriously ,, love your voice 😍😍😍
