It is an adaptation to their parasitic lifestyle. They have flattened their bodies laterally to make it harder for their vertebrate host to squish them while scratching. I find that fact amazing. Other parasites have opted for flattening dorso-ventrally.
@@mariannaluciliasericata4195 Yeah, the adaptation itself is amazing, but I actually find the sheer physics of it even more incredible. Trying to kill a flea by squishing it between two fingers is like trying to destroy a piece of paper by squishing it between two water balloons.
You gotta wonder what the world is like for a flea mid-jump. Total random and hope to land somewhere safe, or intentional and coordinated? Either way, wild stuff.
Did u ever see frogs jump? They kinda just jump but they dont land. Often they just do a belly flop or tumble on the ground until they're upright again
It is coordinated. If you've tried to catch a flea jump in person, you'll see they turn towards the direction they want to travel. It's somewhat coordinated
I never knew adult fleas jumps were so spinny and wonky, always assumed it was like a jumping spider or grasshopper, though without a wide base or wings i can see why they would have such an uncontrolled jump, great work!
I was vacuuming my home and found the larvae in my dust cup of the vacuum. I have never seen the larval state of fleas until tonight. I've been having a problem with fleas in my apartment so I'm vacuuming, using diatomaceous earth, using knockout spray, capstar and Frontline plus on the dog and cat. They are so hard to get rid of!
So here I find myself in the middle of the night watching a video on how flea larva moves; and I find it utterly fascinating! It's impressive how you can make something like this interesting.
That's really very fascinating! It's amazing how an animal known for its legs and leg power doesn't even have any at the start of it's life. Nobody wants to deal with a flea infestation, but they are a really interesting rabbit hole of biology to study. Great job on getting this video!

"Twenty minutes on the floor looking for fleas" yikes. Needle in the haystack got nothing on that! People used to find fleas by walking into the room. And what did you do with them when you were finished filming? I really HOPE you didn't humanely release them into the wild!
The information that you can order hundreds of fleas makes for some cathartic reminder I can always take revenge. Thanks for making informational videos in general.
I'm already intimately familiar with a lot of this (I work in animal welfare and one of my best friends teaches and researches parasitology and entomology in terms of veterinary medicine), but the images and videos are great material. Thanks for sharing prior to publication!
First time seeing your channel. So very interesting, in a fun way. Amazing how many critters must eat either their own poop or the poop of adults of same species in order to be healthy. Thanks for sharing.
Is it a worry that I knew all of this information other than the maxillary palps are used to walk? The benefits of being a stray cat rehome and rehab for many years. Would love to see you do the rat flea too. Now they’re tiny and jump Very well too.
What I'm more interested in is why do so many bugs have a larva caterpillar like stage where they're basically weird worms... Like what is the benefit of that in terms of evolution? Crazy they go from worm like to something so completely different that you'd never guess (without prior knowledge) looking at diff life stages that they're are all the same species....
I always imagined them to be menacing and capable of strategic jumps. This looks more like they should be accompanied by a looney toons spring sound as they blast off, seemingly in just whatever direction.
6:36 The flea larva hauling itself across the carpet sample has small red beads on it. Are those mites? I know that some parasites have their own parasites (which gives a certain grim satisfaction).
Are the movement strategies of other Mecoptera larvar similarly obscure? I wonder if there are similarities, at least with (for example) the Nannochoristids...
Them hooks are good in the wild to hang on the branches, grass,... so they don't fall of and can push themselves more easier. If you put yourselves in their eyes, you would want to move around easier. On solid ground they have a disadvantage. You should film insect on how they move around what occurs in the wild for natural movements. First time viewer here
As a linguist I know absolutely nothing about fleas or biology in general, but nevertheless I'm always happy to see the boundaries of scientific knowledge expanded!
Would love a rove beetle videos, they are awesome and even the larger species like devil's coach horse , and hairy rove beetles fly surprisingly well and unlike ground beetles, rove beetle have surprisingly small elightra and relatively long wings so much so that they have to use their abdomen to fold their wings
so weird finding out what hasn't been looked at regarding insect movement. I mean you even said that fleas are (relatively) well studied insects and yet there was barely anything on the movement of larva
Thanks for sharing this incredible information for free. You bring never before seen knowlegde to the world. By the way, how is it that you were financed to do research on such a niche topic? I find it amazing but seems not that important for most people overall I suppose, if you don’t mind the question.
this is was a small, unfunded, study. behavioral research like this and most of my other studies don't cost that much once we have the equipment or access to it somewhere else.
@@AntLab Oh that's great to know. I would love to do this kind of research on topics about little studied groups of insects. I'm impressed by the knowledge you provide with the incredible camera shots of the insects' close up, and I would like to do something similar at some point. Your videos inspire me, so keep up this great work on your channel. :)
Really interesting! the movement reminds me of some worm creature we have at my house (in Argentina)... I haven't been able to identify it, but its body remains stiff and it almost builds its own "shell" out of what seems to be dust particles, and it moves by poking its centipede-like head out and pulling itself up the wall. I found some similar worms online that use leaves instead of house dust. If you have any clues, I'd love to know
Man Check out the furniture where your dog sleeps if you don't keep it clean and treated-- looks like a zillion tiny maggots in the seams and folds of the furniture. Frkn gross and so many people have no idea
in photography, magnification refers to the projected image on the sensor. If he's using that terminology which kinda fits, then the image of the larva projected on the camera's sensor by the lens is 5x its real-life size.
Also what is the best way to prevent fleas on the property? I live in the country so no amount of products seem to keep them at bay. I wish I lived in the city/suburbs for this very reason. My pets seem to be covered in them all year round. Tried the flea and tick solutions, the vet brand flea/tick, diatomaceous earth rubs on my pets/house. Garlic and no luck. Using dish soap while bathing them seems to do the trick but I want a prevention for them not exactly a treatment, but I’ll take that too!
great job with the flea jumps, I am curious though from a technical standpoint, why so agressive on the depth of field? was it because of the cam? could have been cooler if it was all in focus :(
What I wanted to know is how the heck did you get just larva and eggs in one shot without getting any of the adult fleas within the shot did you just leave it open for all the fleas to jump out and how did you open that container to get one or two fleas without them hopping all over the place I’m pretty sure some escaped in your lab. And trust me, I would love to have your job. What is the name of the job? What type of degree in requirements sign me up I’m on a job hunt and bugs or something. I absolutely love, including my favorites arachnids
maybe. there are still ant colonies in the lab (trap-jaw ants), but I don't have any active research projects on them at the moment. Unrelated, I have been wanting to make a video about ants in amber in museums for a while. I hope I have the chance to make that one.

I admire your self-control to not say "flea-search" at the end of the video.
I was just about to say the same thing
all the good ideas always come after I push publish!
@@AntLab 😅 Welcome to the club! 😎✌️
I wholeheartedly believe you did the right thing not picking the low hanging fruit and thank you for not.
Too intelligent to say that
What amazes (and frustrates) me most about fleas, is that they are almost impossible to crush. It's like they took refuge in a lower dimension.
It is an adaptation to their parasitic lifestyle. They have flattened their bodies laterally to make it harder for their vertebrate host to squish them while scratching. I find that fact amazing. Other parasites have opted for flattening dorso-ventrally.
@@mariannaluciliasericata4195 Yeah, the adaptation itself is amazing, but I actually find the sheer physics of it even more incredible. Trying to kill a flea by squishing it between two fingers is like trying to destroy a piece of paper by squishing it between two water balloons.
I'm glad not all bugs have this adaptation. It's honestly them most broken trait imaginable for a parasite
You need to squash it with your nails to skin. It will break them, if you use enough pressure.
I rub them till they look like a skidmark...
man i love your videos so much .. straight to the point, no blabla, no hooks, just facts and beautiful images
makes you forget what you are looking at ! a nasty parasite that is a true nuisance ! but still amazing to see.
I had to replay 1:59 to 2:04 several times. Thats absurd! It means some one some where is a professional flea farmer.
correct
Amazing captures. Thanks for sharing your findings!
Amazing images (especially from the SEM) and video! Always something interesting in the Ant Lab! 😎✌️
So cool to see your videos popping up on other channels! Thanks for another interesting insect.
thank you so much for your work. i have left the researching field for half a year now and i miss it so much, thank you for sharing this feeling.
You gotta wonder what the world is like for a flea mid-jump. Total random and hope to land somewhere safe, or intentional and coordinated? Either way, wild stuff.
Definitely slow motion with The Blue Danube as a soundtrack.
Did u ever see frogs jump?
They kinda just jump but they dont land. Often they just do a belly flop or tumble on the ground until they're upright again
It is coordinated. If you've tried to catch a flea jump in person, you'll see they turn towards the direction they want to travel.
It's somewhat coordinated
well they detect light, vibration and CO2 in the air so they probably jump towards that
I never knew adult fleas jumps were so spinny and wonky, always assumed it was like a jumping spider or grasshopper, though without a wide base or wings i can see why they would have such an uncontrolled jump, great work!
I love these videos because not only do I learn things, I get to see cute lil buggos jumping/flying/just moving around!
Yet another amazing video I will not be sharing with my spouse...
But definitely one I will share with my louse!
And my house!
Perhaps with my mouse
I don't know why UA-cam has been so insistent that I watch this video, but I'm glad it was.
As a former entomologist, I'm embarrassed to say i never know fleas were holometabolous
you're not alone, I'm an entomologist in college and was suprised to see that they have larvae instead of nymphs
It does feel kind of weird that they undergo metamorphosis. Something about them just leads to the assumption they wouldn’t start as larvae.
I'm ashamed of you, you didn't even think about it?
@@grimportent8792 they really have that vibe
They can easily get confused with louse or bedbugs, which have nymph instead of larva stage.
You folks made flea larvae not just interesting, but captivating!! 👍
This is so interesting! I’m not a fan of fleas but seeing them up close really helps me to appreciate their complexity.
AMAZING shots! and some great research! keep up the amazing work
Congrats on another amazing video on insect motion. As a zoologist and parasitologist, I found it utterly fascinating!
I love what you do ,
but I prefer the moths .

@5:49 "I remember my college days, wild times! What'd you get up in college?"
"Measure flea heads for 6 hours a day..."
Your videos never cease to amaze me. I just with they came out more often!
If they came out more often, they wouldn't have so many interesting (and new) things in them!

Excellent video; you are very good at explaining so the general population understands. Thanks!
You haven't posted anything in 3 months, and now you've come back. I missed you.
This is the nerdiest channel I'm subscribed to.
yr welcome
The information that you can order hundreds of fleas makes for some cathartic reminder I can always take revenge.

I think it's important, maybe even vital to study fleas and other pest insects so we can better understand them and control them. Great work!
As always, fantastically amazing. Great science.
4:57 its important to mention that larval fleas have a permanent derpy face.
I just learned you can order fleas on the internet. Thats kinda disturbing.
They are amazingly built. I researched them years ago. How can something so tiny be made so intricately... especially their legs. God is real❤❤❤
Is it a worry that I knew all of this information other than the maxillary palps are used to walk? The benefits of being a stray cat rehome and rehab for many years. Would love to see you do the rat flea too. Now they’re tiny and jump
Very well too.
Very interesting!!! Thanks for teaching me something that I didn't know!!!!

Wait, this channel is getting so many views now! So well deserved!
You can just... buy fleas?
😂😂😂
Cue diabolic plan. You can also buy a few different types of manure to have sent anonymously through the mail through a service
The maxillary palps at the lower head reminds me of the front legs of my greek turtle. - Your videos are outstanding!
I didn't expect to ever watch a flea unboxing video, but here we are. Also why are larval fleas actually somewhat adorable?
Very nice. I've never thought of how flea larvae move
2:12
"Flea feces with eggs"
Thank you, just what I always wanted :D
I always imagined them to be menacing and capable of strategic jumps. This looks more like they should be accompanied by a looney toons spring sound as they blast off, seemingly in just whatever direction.
Keep up the good work!
Watching fleas yeet themselves in slo-mo is something I didn't know I needed.
Anything that sucks blood makes my skin crawl. Fleas, ticks, mosquitoes, ex wives...
6:36 The flea larva hauling itself across the carpet sample has small red beads on it. Are those mites? I know that some parasites have their own parasites (which gives a certain grim satisfaction).
dudee we missed youu
Watching the larvae crawling sure explains why diatomaceous earth works so well to combat fleas
Are the movement strategies of other Mecoptera larvar similarly obscure? I wonder if there are similarities, at least with (for example) the Nannochoristids...
in slow mo, they look like they just rise and float away while spinning like a gmod model
Superb video, thank you. That slow-mo footage must have taken *ages* to record. Zack Snyder would be proud! 😂
Them hooks are good in the wild to hang on the branches, grass,... so they don't fall of and can push themselves more easier. If you put yourselves in their eyes, you would want to move around easier.
On solid ground they have a disadvantage.
You should film insect on how they move around what occurs in the wild for natural movements.

Weird how you can see the throughgut of each flea larva filled with the gross mixture they eat through their exoskeletons.
Very interesting and fascinating to watch.
neat history review on a buggy subject
The fact that you can buy fleas makes me think that some people out there are playing very mean pranks
The way that first flea lifts off into the stratosphere tho
Now i feel like stuff is crawling on me.

ihatefleasihatefleasihatefleasihatefleas im so itchy WHY DO I KEEP WATCHING WHY IS IT SO FASCINATING I HATE FLEAS SO MUCH
I think its human nature to want to learn more about the things that scare or disgust us; it's a good way to confront difficult stuff.
So you can more effectively keep them from infesting your space!

"I have to go, my planet needs me"- The Flea
Damn! love the video but Jake was my favorite part
@4:30 What do you mean X 5 magnification? These things are filling my screen, but they're only fleas. Explain?
in photography, magnification refers to the projected image on the sensor. If he's using that terminology which kinda fits, then the image of the larva projected on the camera's sensor by the lens is 5x its real-life size.
this is correct. it refers to the macro lens which is viewing the subject at 5:1 magnification.
I'm very interested in why you can order fleas? I can see that need for studying purposes. But do other bugs or insects feed on them?
for science, mostly, i think
0:00 the jump 💀
The most surprising thing about discovering larval cat flea is that it means cats have a larval stage and I have never seen one!
i wanna know what larvae to adult flea looks like now
Show them side by side with adults to show how big they are
Good video Ant Lab.
Does the larvae sense smell and or seek it or a light what prompts a direction heading>>>
Also what is the best way to prevent fleas on the property? I live in the country so no amount of products seem to keep them at bay. I wish I lived in the city/suburbs for this very reason.

great job with the flea jumps, I am curious though from a technical standpoint, why so agressive on the depth of field? was it because of the cam? could have been cooler if it was all in focus :(
have you tried glass surface or any smooth surface that wont allow them to grasp ??
I hats flees, the larva were so itchy and then soon the biting started
What I wanted to know is how the heck did you get just larva and eggs in one shot without getting any of the adult fleas within the shot did you just leave it open for all the fleas to jump out and how did you open that container to get one or two fleas without them hopping all over the place I’m pretty sure some escaped in your lab.
