Leaf Miner Fly Babies Scribble All Over Your Salad | Deep Look

- This fly’s larvae tunnel inside bitter-tasting greens like arugula and kale, leaving squiggly marks behind. The plants fight back with toxic chemicals. So before laying her eggs, the fly mom digs into a leaf and slurps its sap - a taste test to find the least toxic spot for her offspring.

As they feed inside a leaf’s spongy layer, leaf miners etch intricate patterns that are visible to us on the leaf’s surface. The whitish tan or light gray markings can be neatly serpentine or converge and have a blotch-like appearance, depending on what insect made them. Many different flies, butterflies and moths lay eggs on the leaves of citrus, vegetables and ornamental plants that grow into leaf miner larvae.
One leaf miner that gardeners might find in their arugula is the larva of a fly called Scaptomyza. The fly is related to - and looks a lot like - the fruit fly you might find buzzing around your ripe bananas.
The chemicals called isothiocyanates that give leafy greens like arugula their bitter taste are precisely the plants’ defense mechanism against pests. Scaptomyza flies have evolved to tolerate low levels of these compounds. One way in which the flies deal with these toxic chemicals is by laying their eggs on the leaves with the lowest concentrations.
---
--- Can leaf miners kill plants?
Leaf miners rarely do enough damage to even come close to killing a plant, but they make individual leaves inedible. If given enough time, a leaf miner can be particularly damaging to vegetables that are harvested specifically for their leaves. But don’t worry if you mistakenly eat a larva - it won’t make you sick.
--- How do you treat leaf miners?
Most backyard gardeners only need to remove the damaged leaves by hand. Since leaf miners are tucked inside the leaf, insecticides aren’t very effective and can hurt beneficial pest predators like wasps, spiders and ladybugs.
Gardeners with a greenhouse or large numbers of plants can use parasitic wasps to control leaf miners.

Hi Deep Look fans! Want to learn more about how Scaptomyza fly moms choose a leaf to lay their eggs, or find out what makes the curlicues in your citrus leaves? Check out this article by Deep Look intern Marissa Sandoval: www.kqed.org/science/1973500/leaf-miner-fly-babies-scribble-all-over-your-salad Thanks for watching!
Lol
hi
Hi early
hi not so early
DEEP LOOK : When you learn the bugs in the yard are eating a healthier diet than you do !
( Arugula, Kale, Wild Mustard - leavy greens ! )
Man, I feel for the plants. This is literally bugs crawling just under their skin.
@@pitioapolo I really wish I didn't read this comment 😭
Plants have feelings, too. They don't want others to cut them, chew them, or infest them.
We have mites living on our face.
And they said eating vegetables is not like butchering
Crawling in my skin!
*"Welp, back to the ol' leaf mines"*
🌿⛏🐛
*I am a grub and I'm digging a hole, diggy diggy hole, diggy diggy hole*
Dig a hole, dig a hole.
@@peculiarjack617 people of culture oh wow, i got flashbacks
😠👎I'm not falling for the deception here! When you see miners continuously mining a particular area, its because they FOUND SOMETHING VALUABLE THERE, like precious metals and/or precious gems! So its my theory that these leaf miners have struck gold, silver or emeralds in these leaves! 😮😲😨
@@HighlanderNorth1 bruh, it’s a joke
Note to self: Don't eat food while watching Deep Look.
Rookie mistake. Unless you're from a country that eats bugs.
heh, I watch deep look while eating food most of the time
I always eat something while I watch this channel 😂
I’m eating spicy chips rn lol
Did u choke while eating and watching this?
The foley artists for DeepLook need a raise. I totally felt that leaf's pain! Keep up the great work guys.
I said the same thing too, the Foleys here are top notch, makes me think those things would actually sound like that if they were on the "human macro" level.
It sounds so... moist.
Yeah you almost forget there is no way they make that sound or those sounds. At the very least there's no way we could hear it.
But lady on TikTok told me "plants dont feel pain!"
A job I always wanted but never knew what it was called until I was in my 20s.
Random person: Nature is always so beautiful
Me: Nah, you're just not looking deep enough
Still beautiful in its own way
This is pretty tame all things considered.
If you have a boring, domesticated idea of "beauty", sure! But give me the wriggly, dirty and slimy! That's what's makes life alive!
@@eldritchtourist still more beautiful than the political world of men.
@@SimonWoodburyForget This (way too common) argument would make the term pointless... Natural literally describes things that humans didn't have a part in creating.
Ok I was not ready for the ovipositor footage.
RIGHT WTH
😩🤮
No one was... 😶
Imagine being the male fly, the ovipositor could cut them pp
Same😭😭😭
Drosophila: fruit fly
Scaptomyza: the cooler fruit fly
lol
I've never been this interested in flies before. Nature's so amazing - how the female digs with her ovipositor INTO the leaf is incredible
Flies are very interesting little dudes :) Fruit flies have actually helped out a lot with medical as well as mental health research !
I love how when they showed that clip of the fly it looked like it was rubbing its hands together like an evil genius. Did anyone else see it like that 🤣
😂😂😂
When is see flies i always see them do that😂😂😂😂
I used to love looking at insects when I was a kid and I’d observe the same with the common housefly ... I would think this rubbing as similar ... but less evil, and more “... eureka! I’ve arrived at a huge food park!”
@@smallstudiodesign I thought it was both, and I’d wave the villains away.
They actually cleaning their feet.
For the second time I'm here when I should be doing my homework lol
This is educational as well
I am always here when I am supposed to do my hw
What’s there to lol, most of the students here have pending works.
Me too
2:03 Her um Overpositor kinda looks like a Venus Flytrap
So thats why my salad was so juicy today....
*S* *H* *R* *I* *E* *K*
They eat the leaves from the inside, making them hollow and tasteless, so shouldn't it have been _less_ juicy?
@@chitinskin9860 way to ruin the joke
@@HuskitaLover It's what I do.
Seriously it's the closest thing I have to a talent and I hate it.
@@chitinskin9860 alright, psychopath 😝
@@HuskitaLover Seems like a bit much over correcting a fallacy, but ok.
Plants: *creates bitter tasting chemical to deter animals from eating them.
Humans and leaf minor larva: "Jokes on you, I'm into that!"
Hm yes, leaf child larva
You're so cool, haha!
Some humans don't like greens as a result. I guess this is why.
Plants: **Evolve to make eating their fruits and vegetables cause extreme pain**
Humans: Mmm, pain
Nah those chemicals just make me throw up
The camera man has the most steadious hand I've ever seen.
And a stomach of steel!
I hope it's a joke and you realize they use a tripod or some other equipment. I mean did so many people really believe a cameraman could keep his hands still for several minutes to create those sped-up shots. I hope not
@@bobthegoat7090 I'm 100% sure you are right but I think some of those shots were done by hand as seen at their Behind The Scenes video. So let's just take the compliment and let it be.
All the closeups get studio shot. Outside, the slightest wind is enough to spoil any macro shot
Deep Look: Both have to ratchet up defenses to survive
Plant in 3021: *develops acid sap*
Fly in 3021: *carries shotgun*
Plant in 4021: *uproots itself and runs away from fly*
Woowww...I never realized how amazing all the little things that I never see are.
Thank you !!
Glad you enjoyed it!
So.. minor miner flies. Got it.
I like how deep look just tells us every detail about insects
Me: I should go to bed now and get some sleep
Also me :
lol fr i jus be lookin at Deep Looks videos ab flies
Imagine you're going to die if you leave your blanket
It's kind of funny how much two species battle it out in an evolutionary one-upping each other. Bugs eat plants-> Plants produce toxins-> bugs resist toxins-> etc.
Wow, leaf miners!! Why have I thought that larvae would only crawl and eat on the leaves?!
This is very informative! Thanks, Deep Look!🤗👍
By the way, I may not eat salad for a while…😅😅
Protein
@@horiginsfs7561 Yeah, we need it, too. 😅😅
let's appreciate they're hard work to make this 4 mins videos
They are appreciated
I can just imagine the plants being like:
*A fly wounds you and tries to put eggs on your tissue: panik!
*You are an expert in chemical warfare especialized in killing insects: kalm
*Tha fly is into that: PANIK!
"the fly is into that" lmaoooo
Ok
Why you guys are so underrated??
With 1.7 million subscribers I wouldn't call them underrated.
@@perplexingperceptions8888 no they deserve atleast 4M lol
In what world is 1.7 million subscribers overrated?
1:31 ‘the fly is rubbing its hands, thinking of its evil plane to kill this plant’
Oh wow, I just ate a salad today... Thanks- 😬
This is by far my favorite youtube channel, it's somewhat very entertaining and educational! I just love to watch it every other day after school, please keep up your amazing work Deep Look
This is how cows get their protein
You guys deserve far more subscribers. You videos are of awesome quality 👌
Your*
I love the musical accompaniment for all these episodes. Y'all should drop an album!
They love music, especially the song, "Leaf Miner's Daughter"
I just woke up for school and I should be leaving but I started watching these and I can’t stop
Go to school
*GO SCHOOL*
You know that’s what the people who make these would want!
I get more education here than in school lol
@@brighamruud5090 youre so right. My school did nothing for me so i research the topics i want to peruse.
@@lemonblossom0 yos
i've never been so early in a Deep Look video! 😍
Hope you enjoyed it!
Same
This is creepy yet amazing :O
Me asking myself : Why I am fond of Deeplook uploads?
1. Interesting Information
2. Quality of Videos
3. Soothing Explanation
4. All the Above
Their cameras, and their crystal clear detailing is everything. 👍🏼
Don't forget the amazing voice actress
I love how the video is just 4 minutes long, and is only 2 minutes when I put it to 2x speed. Short amount of time, but very educational! :D
math!
But how minutes is it if it's a 3x speed?!
@@chrizze6542 hmm, 1.3-ish minutes?!
*Soooo basically they’re leaf scabies......*
I've gained a new appreciation for Deep Look after spending so much time in the garden during the quarantine.
lol imagine them in aloe vera leaves😂 soo much space
This channel deserves wayyy more subscribers because of its super informative videos....
Imagine in a forest and seeing a fly twerking on a leaf
Seriously people. Even if you are disturbed or disgusted, don't click on thumb down. It's not fair. You are doing wrong. This channel only deserve praises.
Laura alway make me happy, keep it up Laura!
That fly be rubbing its hands together like it hit the jackpot.
i _really_ do not want to imagine these in my skin
I read a book series with worms like that. Two actually, now that I think about it. One was the Eragon series, the other was the Gone series by Michael Grant.
Fortunately for you, no leaf miners ever engage in behavior like that. They are pure herbivores.
Unfortunately for you, screwworms exist.
@@chitinskin9860 *welp*
@@chitinskin9860 oh god i wish haven't searched up "screwworms in humans"
pure nightmare fuel
Every body gangsta until the larva start mining human skin
leaf: exists
Fly: Rubs hands together
Thank you for providing such insightful videos and all the information you add to your description!!
Soooo interesting! Thank you Deep Look for expanding our world
Cute
Fly: Eureka! Food park!
Plant: No! My leaves!
Fly and larvae: You wish.
Deep Look, I like how you never run out of new animals to talk about!
OMG I just saw one of these marks on some leafs in my back yard! Thanks for making this video I really enjoyed it!
it's like a ✨Butterfly✨ *BUT WORSE*
Thank you always for the high quality videos and information!!!!!
I love her voice!
You never cease to amaze me, disgust me, and make my skin crawl...
Hope everyone's eating a salad while watching this today.
Arms race: we all know its ends, when the plants will have nukes.
When I see notification from deep look, I come jumping in to know new stuff🥰😌 you guys are doing a great job!!😊
Deep Look deserves the whole world,yes.
Beautiful work as always !
Thank you for your hard work in making these vids
"😮" my face everytime you guys upload something and the detailing you show...
Hats off 🔥💯
Imagine them making modern art- oh wait that IS modern art
Did I ask? No.
Did I enjoy? Yes
*you know your not the favorite child when ur mom puts u on a toxic side of the leaf*
I cannot even imagine the Hardwork invested into making just 3 Seconds of the Video 😳
Awesome Team DeepLook 🙏
Your Editor, Cameraman and Narrator needs an Immediate Kiss on theit cheeks 🥰😍💕
Their newborns can feed themselves, so efficient
I love "Deep Look".... I just
... freaking love it.
Yeah, this is my favorite animal/insects documentary channel
Quality of footage as usual. Very intriguing revelation unnoticed otherwise!
Wow! Thank you Laura you’re awesome
thank you for another masterpiece!
I really enjoy your videos they are so interesting thanks for todays video!!
Glad you like them!
Incredible camera work!
Interesting facts as usual, looking forward to the next episode. 👌🏼🔥
Nice video again!!! My DeepLook friends!!!! Kudos to you all!!
Dang her voice is so relaxing that it made me fall asleep lol
Every time at the end I feel the video should have been a little longer than usual, I feel like why did it end.
Love your videos 😘
Nature never fails to fascinate.
Wow! Iv seen them on our tree before, but never new what they were
Wow guys!! This is just wonderful 💚
How all that could have evolved in step by step sustainable increments from a single cell is something yet to be explained by science.
Truly fascinating! Wow! Also, I'm not gonna be eating arugula, dandelion greens, & other such fly/larvae delectables anytime soon. I can be fascinated & revolted simultaneously, apparently.
fantastic, more Deep Look!
Thanks for your usedful video! 💕💞 I love u, Deep Look Team 🙏
From Cambodia
Love your hard works from Deep of my heart 💕💕💕
I love this narrator
Mmmmmm......those are my favorite greens too. These little guys have good taste.
Leaf miner larvae are the best!
If you can't be a Patreon just watch the Ads until the end that also helps 💖💖💖 Great video once again
Great content by @ Deep look ...Why this channel is underrated ?
So, clicking on this half way through eating my salad might not have been the best idea.
Thank you for making my day everytime you make a video
Another great masterpiece!
yay deep look uploaded a new vid!!
