- Dragonflies might rule the skies, but their babies grow up underwater in a larva-eat-larva world. Luckily for them, they have a killer lip that snatches prey, Alien-style, at lightning speed.

If adult dragonflies are known to be precise hunters, capable of turning on a dime and using their almost-360-degree vision to nab mosquitoes and flies in midair, their dragon-looking babies are even more fearsome.
Dragonflies and damselflies lay their eggs in water. After they hatch, their larvae, also known as nymphs, spend months or years underwater growing wings on their backs.
Without those versatile four wings that adults use to chase down prey, nymphs rely on a mouthpart they shoot out. It’s like a long, hinged arm that they keep folded under their head and it’s eerily similar to the snapping tongue-like protuberance the alien shoots out at Ripley in the sci-fi movie Aliens.
A nymph’s eyesight is almost as precise as an adult dragonfly’s and when they spot something they want to eat, they extrude this mouthpart, called a labium, to engulf, grab, or impale their next meal and draw it back to their mouth. Only dragonfly and damselfly nymphs have this special mouthpart.
“It’s like a built-in spear gun,” said Kathy Biggs, the author of guides to the dragonflies of California and the greater Southwest.
With their labium, nymphs can catch mosquito larvae, worms and even small fish and tadpoles.
“It’s obviously an adaptation to be a predator underwater, where it’s not easy to trap things,” said Dennis Paulson, a dragonfly biologist retired from the University of Puget Sound.
Also known among biologists as a “killer lip,” the labium comes in two versions. There’s the spork-shaped labium that scoops up prey, and a flat one with a pair of pincers on the end that can grab or impale aquatic insects.
-- How many years have dragonflies been around?
Dragonflies have been around for 320 million years, said Ed Jarzembowski, who studies fossil dragonflies at the Nanjing Institute of Geology and Paleontology. That means they were here before the dinosaurs.
-- How big did dragonflies used to be?
Prehistoric dragonflies had a wingspan of 0.7 meters (almost 28 inches). That’s the wingspan of a small hawk today.

I really appreciate the production quality of your videos. I would happily watch a feature-length documentary series, if you were ever to produce one.
Thanks!
but for real i really appreciate the quality of this channel and its one of the only reasons i come on youtube thanks for doing what you do
How does the videographer get such a wide depth of field for such magnified macro shots without cranking the aperture to f/30 or higher. Also how do he/she maintain such perfect focus on the moving creatures and stay locked on because it's almost like looking through a small microscope. I have a 1:1 macro lens but it could not come close to these videos close up and tracking the moving insects. I would love to know in more detail like behind the scenes like the type of lens and the technical terms for photographers. Amazing videos. Thanks!
You're welcome!
Yeah it's so crisp.
I didn't know dragonfly's eat mosquitoes.
Now I love em.
@@ronangrandchase1079 what?
0.0017% saved from dengue
They can also eat your nose 😂
Ye
And flys
Seeing that Mosquito larva get eaten was most satisfying.
Xengoku I agree with you
sooo true
Its probably even more satisfying watching an adult dragonfly eat an adult mosquito
no mosquito yes life
Well then the government should stop the chemical spray and begin to cultivate this thing
Omg they are smiling, I'm CANT STOP SMILING.
Your dp says it all

I always thought it’s a mini helicopter
Its local name in india
@@hardeepbabhauri7379 yeah, in Pakistan too
In México, some people actually just know them as "helicopters" lol
There is slot of dragon fly here lol
Well, actually the idea if helicopter was appeared from dragonflies. :D (but seriously, this is true).
they eat mosquitoes.
they are my favorite insects now
But I don't want them to be extinct though, because they lived longer than the Dinasour or the Dinasour era.
@@leotrace9158 ,indeed.They are important for the ecosystem
@@mazadancoseben4818 That's something I can laugh at.
Swallows: am i a joke to you?
They forgot to mention that they can also move each wing individually, precisely, and all simultaneously. Now that's the zenith of natural engineering.
NEMO NOBODY i don’t know what zenith means.... but! i’ll just say it’s the new fortnite skin.

We need way more of them skeeter eaters.
Thanks Deep Look. I'm never sleeping again.
Our work here is done.
Nvm, i cried
If all humanity saw this most will die from lack of sleep
PBS Digital Studios Nice very original comment about not being able to sleep. Blocked.
Katelyn make some videos lol
0:58 Lol the blue dragonfly stepped on the red dragonfly's wing
mmm.. It actually tried to mate...
Blue dragonfly got beef with red dragonfly and nobody knows why 🤔🤔
@@sagerotusj7504 It's the Crypts hoverin' up on the Bloods.
They be Gangstaflys.
Bloods and the crips
@@sagerotusj7504 if you try to catch them , blue dragonflies rarely bites your finger but the red ones ? The red ones have jaws
I’m so happy I found this channel, the production quality and all the facts are just so perfectly laid out. Keep up the good work!
Thanks James!
Yeah, you eat those Mosquito larvae to your hearts' content Dragonflies. Wipe em' out!!1!1
Keith@tidbithoughts but would that wipe out the dragonfly because they don't have anymore food.
Av Vu They eat other insects too
M & M yea but the mosquito are the most abundant and some dragonfly species only eat or rely heavily on mosquito.
This is the kind of homework i want, watching deep look videos
SAME
bittersweet i
I was just casually watching the video when an actual dragonfly suddenly flew beside my pc. I had to scream
I bet the dragonfly was like 'You rang?'
Dragonflies are the best idk what u screamin about
Do you scream when you're happy, whenever a slight coincidence occurs, or just everytime you see a dragonfly by a PC?
😏
"a baby dragonflys mouth will give you nightmares"
Me: Welp it's the middle of the night, WhY nOt
"a baby dragonflys mouth will give you nightmares"
Me seeing it eating mosquito larvas: Its a dream come true
yeah me too XD
i was like HeY iT's ThE pErFeCt TiMe To WaTcH tHiS
They eat Mosquitos? Bring back the two foot long Dragon Fly!
The Banana Melon No because they would eat something useful like bees and hummingbirds 😦
fenrirgg
They can’t kill all bees but could still get a couple and i think hummingbirds can be faster than a large insect
Then they would eat babies
Im fine with more normal sized Dragon Flies.
They absorb oxygen through their skin and since the oxygen concentration dropped, these would die from asphyxiation.
If they ate mosquito larvae, I'm perfectly okay with that. They should eat more! I hate mosquito that much.
Nanna Leifa mosquitos are not common or even absent in ponds with healthy numbers of predators, esp water boatmen, dragonfly larvae and fish. Mosquito larvae prefer stagnent water, or small containers, gutters, water butts etc that do not have predators living in them.
Malaria is gonna go extinct
Just Some Cat is that so bad?
Nanna Leifa
Yeah. I agree. And mosquitos are the most dangerous animals on earth.
Yup they carry god who knows what kinda diseases
People get very sad when they learn the fact that such beautiful creatures that dragonflies are live mostly about 24 hours, sometimes more, but they don't know the fact that their larvae can live up to 5 years underwater and devour everything that moves.
I always loved dragonflies. That's a good dragonflies, that's a good boy
Gud boi.
Their Spanish name is "Caballitos del Diablo", meaning Devil's little horses.
That's a great name.
SoZ1646 but there so adorable
@@Ecktor Libelula is called in Spain. Maybe he was calling latin spanish.
@@danielsanchezsegura2525 here in Argentina we call them "libélulas" too
Caballetes
Imagine gaming with both hands and having your lip do the eating for you. I'm jealous.

I *_can_* eat with only my mouth so......^~^
@@IdiotToonz they mean that they would like their lips to pick up food by themselves and eat it
@theni I agree, it would make gaming while eating so easier, but it would look weird af xD
@@thefallenleaf8029 oh you mean like not moving your head at all? Well I can't do THAT.
Yoooo. Imagine how big these dudes would be 300 million years ago. No pond would be safe.
They were much much more larger in size in comparison to what they are at the present. Some were even expected to feed on smaller animals of their size so basically carnivorous. Thankfully they became extinct a long time back. What is left now are their enormous fossils which gives us an idea about how big they were.
Yeah, trying to picture baby larvae of those giant dragonfly ancestors. I imagine they were tye stuff of nightmares.
But, I wonder if you could have ate them like lobster, crayfish, or crabs. Water bugs n all that.
Lauren's voice is so soothing. Makes me enjoy binge-watching these.
0:25 aww it's like smiling :)
good eye! It looks like a cute version of Imperfect Cell from Dragon Ball Z
They eat mosquito babies???? MY HEROES!!!!!
Aggelos M mosquito larvae are DOOMED
Dragonflies are some of the weirdest, coolest insects in the world. Nature is incredible.
I adore Dragonflies. I loved them since I was little. They were always so fascinating to me! And now that I know they eat mosquitoes..I love them even more!!
We have a small artificial pond. This year, it was full of both tadpoles and dragonfly nymphs. They coexisted for a while, but eventually the nymphs got so big that they started eating the tadpoles. It was a gruesome sight.
Yeesh... I guess... they knew what the tadpole would've grown into so it's either eat or be eaten.
I hope these larva dragonflies can help to reduce the population of the mosquitoes especially the dangerous one.
You mean Aedes Aegypti?
Its not all the fault of mosquitoes tho, what causing dengue fever and malaria is a parasite called Plasmodium the mosquitoes is only carrier

But mosquitos are still to be blame for spreading it. Bed bugs for that matter do not spread any diseases, because of the way their mouth works.
@@DemanaJaire while we should manage the disease or the mosquitoes depending which is better, the mosquitoes don’t have any idea that they’re infecting their hosts and all they’re concerned about is using blood to make eggs. Because of that, hopefully we can manage the disease themselves.
Nobody:
RUclips Algorithm: Yo you wanna see a baby dragonfly's mouth?
sure why not
Imagine if you where a baby dragonfly and all your friend get out of the pond in like 3 months and you just sit there for years and they always make fun of you like, «You still rely on your cradle?»
Its basically like being late to puberty,
Yeah, thats when you said: it's because im waiting for your children ;)
And this can also be applied in real life too, how delightful
so uh, who else just found out dragonflys can bend their bodies like that
Celery Skeleton Well, they also do that when they mate. Male hold female after mating. Without bending it's body it would be slightly difficult to do that and fly at same time. ;-) They do that to prevent further mating with other males.
I always found dragonfly's amazing everytime time I saw them in the wild, but I never saw them this closeup and with this much detail, this was wonderful, the way you shot them, and the editing, and the narration, and the music, everything was perfect in this video as always, you never disappoint, this channel is epic, keep doing more.
i find dragonfly's "scary"

Rock Shorii I'm glad that I won't sleep again
I wonder if it's possible to buy dragonfly eggs and put them in every water spot in the summer in order to eat mosquitos larva. This could be a natural way to deal with them without extra damages.
Hi DrBLOOD. I produced this episode of Deep Look and the same thing occurred to me. Mosquito abatement districts will give pond owners mosquitofish to put in their backyard ponds. But they don't give out dragonfly eggs or larvae. Thank you for watching! --Gabriela
This would be artificial too haha
it IS a natural way to fend off mosquitos but the introduction of dragonflies into a new territory isn't a natural thing that happen so easily. most of the time, it's not beneficial. What I'm sayin' is, if it escapes, it might be an invasive species.
@@Jin-cj3gl No way, dragonflies are awesome. They are actually closer to endangered than invasive in most places. They only lay eggs as an adult, which is only for 6-8 months, but the larva take years to grow into adults. They eat flies and mosquitoes, the most annoying pests, so who wouldn't want them?
Only in places where they are a problem though, and with native dragonflies. It’d be damaging to do it in places with harmless or non-biting mosquitoes.
I've been a fan for almost a year now and Im still thinking why you havent reaching millions of subscribers when you deserve to be more than that! Thanks for the information and your efforts to do a superb production! Merry Christmas 😍
I am happy that you made a video of Dragonflies! Before me, I had a baby brother (Which is not a baby now :-), He's about 16 now?) Who died of disease carried by a mosquito, He could've lived IN the hospital if my Mom didn't let go. But she saw how he was suffering and didn't want to see it anymore, So she spent his last hours at home. At his burial, It was fall when we buried him. Weirdly enough, Dragonflies we're all over his coffin. My Dad shoo-ed them away but we have a suspicion that whenever we see just a unusually small dragonfly, We think it's him visiting us every now and then. :)
Thanks if you read this whole thing. :O
When I was a little and I was going to a pond to catch mosquito larvas as food for many aquarium fish we had. Once I brought this monster home and put into the aquarium. I remember this lower jar shooting forward. I remember transparent body it had. It lived there for some time. I really enjoyed watching it feed. Thank you for bringing these memories =)
Awesome video, this makes me appreciate damselfly larvae because they kill baby mosquitoes
The perfect organism. I admire its purity.
I am so thankful that knowledge like this keeps coming to me. Trust me, nature is extremely underrated!
2:58 do you see that larva bleeding

"Do you bleed?"

I like dragonflys, but now knowing they eat masquitos no matter if they are a baby nymph and an adult, I love them even more.
Dragonflies are criminally underrated
The mouth gave me both nightmares and inspiration. Great video!
I've raised a few dragonfly nymphs before,cool creatures!
+LagiNaLangAko23 no,wild caught.there is a pond by my house where I find them.
LagiNaLangAko23 dragonfly nymphs are real easy to find, they usually just go along the bottom looking for food.

These videos are so interesting, such high quality content. I'm loving this channel.
The quality of the videos so far has convinced me to sign up for curiosity stream. Hope I get to view more of such content there.
Hmm why don't we just put dragon fly larvae in water where mosquitoes put their larvae in
The unknown XD well dragonfly nymphs live in ponds and lakes etc and mosquitoes do too.
hmm good point
Insects are so weird and fascinating, I just started to get into Jumping spiders but great quality on this shortie..

Good god
No information given ur fist bb
I once read a book on my back porch one evening and a dragonfly perched on the corner of my book and shuffled over to the next page every time i needed to turn to the next page, it also would occasionally fly over to my pool and pick at the drowned bugs on the surface and come back to the same spot! They're my favorite bugs
NOW I LOVE DRAGON FLYS ALTHOUGH I STILL LOVED THEM BEFORE I WATCHED THIS BUT NOW I LOVE THEM MORE!
I used to capture these guys and put them in a bottle with tadpoles, I'd just watch em eat all of em. . . I know twas an evil thing to do but was a child and I found it cool.
me too! :D i still do it today
SAME
It's not evil, it's the circle of life, more specifically the food chain, it's completely normal
If you put a few of them together without food.... it might end up like the cannibalistic hunger games.
That's evil
if only humans evolved this kind of mouth piece, all of us here will be very awesome looking!
Seeing those mosquito larvas struggling for their lives fills me with satisfaction.
Dragonflies are such beautiful carnivorous insects and the fact they eat the children of those disease carrying bloodsuckers I have to thank them even more for existing
"Let's hope it stays this way for a few million years"
2045: *gonna have to stop you right there*
You cloddy smartyy....Yeahh
People from 2045 gee I never knew dragon flys were that small
Quality is amazing geez
That's cool! The dragonfly larvae eat the mosquito larvae underwater, while the adult dragonflies eat the adult mosquitos in the air!
I made sure to finish the ads before the vid. Your channel deserves more subscriptions and views and funds! ☺ keep it up!
This is the kind of homework I want, to watch deep look videos
Thanks!
When I was a child I used to tie a thread to dragonfly and fly it like a kite ,had I only known
How on earth did you manage to do that
omg we as kids did that too... but now all grown, I think it was soo cruel of us...

easy to catch by their wings if they are resting and if you are fast enough

These videos are so good. Perfect quality, educative narration. This is my all time favourite channel. ♥️ It
I really remeber when my mom and my brother and me always tries to get A dragon fly and release them after , its the most lovely memory i haved
Welp gonna release dragonflies at my place
Tomato Tom I did that. I have a small pond in my backyard with tons of mosquitos in it. So I caught a bunch of dragonfly babies and put them in there, my mosquito problem disapeared almost instantly
M & M plus you get beautiful and majestic insects to live near you
Hey Deep Look here's a interesting challenge, a video about the Synoeca septentrionalis also known as the Warrior Wasp or Drumming Wasp. I have never seen a high quality video about these rather intriguing and yet mysterious little monsters.
I LOVE Dragon flies, so pretty ☺️
I once saw one dangling from a spider web still alive, I got it down and cut the spider web from the wings and saved it (:
"Dragonflies have almost 360 degree vision"
How do I keep catching them
This reminds me of an anime called PUPA
Darner:darn it can't get mosquito larvae
Fun Fact: In the TV show "Friends" Ross had a fossilized prehistoric dragonfly as a wall decoration in his apartment. I don't know if it was a real fossil. But, it was actual size.

At least they're killing mosquitos
