- It has long been thought that butterfly and moth evolution was largely driven by bats but recent studies have shown that many of these features have ancient origins predating bats by a large margin. And in fact butterflies may owe their evolution and success to flowers not bats.

This made me laugh way harder than it should’ve.

Some tears are produced to keep the eye wet but we don't feel these tears
Got yourself the start of an emo song there. Nicely done.
This is hillarious! Those moths are cold hearted😂
I love the honesty of the constant, "here's a reasonable-sounding explanation for something," followed by, "but actually, it turns out not to make sense."
However!
It is random, but a logical adaptation. The non logical mutations are deleted from the gene pool by natural selection.

Not really. Some mutations are so specialist that they may thrive until a slight change of it's habitat. Sometimes the mutations are a severe detriment to their species longevity.
@@jordan_roadhouse4798 well, if they have no impact in reproduction they will not be detrimental for individuals. Eg: pale skin in tropics. You will get more chances of melanoma, but when u develop it will be in a non reproductive age. Of course socially it can have impact on ur children, but if talking strictly about spread the genes it has a detrimental effect on individuals survival, but not on the species.
Moths have ears? So they can hear me telling them I love them?
Yes! Tell them how much you love them every night. They will appreciate it
Even pigeons have ears
They won’t understand though 😢
I guess they could hear me say I will eat you then I proceeded to eat them.
Ok
The hummingbird moth is insane. It convergently evolved to look like a hummingbird and fly in a similar way. When I first saw one I had no idea it existed, I thought it was a hummingbird but was horrified to see it had insect legs and antennae.
That's terrifying
I remember as kids we also didnt know and thougt it where hummingbirds escaped somewhere. So we spent days trying to Catch them just to finally realize they where infact insects..😂
@@kingpotato7183 No it's not, it's just another variety of animal
Sphinx moths are really fun. Several diurnal species and a lot of crepuscular species. In addition to the many species that converge with hummingbirds there are a decent number of bee mimicking species. Some species have really pretty colors. Plus they are wonderful pollinators.
Likewise. I had no idea they existed until I saw one this year!
A channel called Moth Light finally making a video about Moths.
Should we tell him?
@@alcyon7536 tell him what?
@@alcyon7536 butterflies are a kind of moth
kraken omg I died when he said moth cousins 😂
He got there but it was funny
Birds: Nooo, don't drink my tears ;(
Moths: Haha, proboscis go *succ*
Wait so you're telling me there's a moth out there that drinks the tears of its enemies? That's so metal
Mhm.
Your tears are delicious!
Yes. And I believe some butterflies may drink blood
@@kyrab7914 if there's one that drink sweat, then the trio sweat, blood, and tear drinkers is completed
@@qweqwe9678 google says there's some bees that drink sweat and tears
Arthropod evolution needs more love. Vertebrates are cool and all but we need more of our armory bois.
Their evolution is harder to document since most of them found their niches in the biological tree with plants and fungi long before vertebrates even left the water. So their drastic proto-bug fossils will be a lot older.
Mollusks tho?
ikr insects (except for cockroaches ) are pretty interesting creatures armor gang
@@cerridianempire1653 roaches are interesting too tho, especially the ones that aren't house pests
You must love Hollow Knight
I think my favorite part of this video is the laying out this beautiful theory about how butterflies evolved from moths to avoid bats that seemed to fit all the evidence and then was completely thrown out the window when butterflies were found to have existed during the time of the dinosaurs. Science is fun for how it can crush things like that. :)
But even without that evidence, as the video says, it’s dumb to evolve to be active in the daytime to avoid bats, since now you’ve got to deal with birds instead which is just as bad.
Idk if the other theory that butterflies switched to the daytime to drink flower nectar works either. It's not like moths are flying through the night hunting leopards 🤔 Don't they also drink nectar?
Even though I studied acoustics as part of my music degree... It had never occurred to me that the fuzzyness of moths reduced reflection of sound but yeah that would totally be useful. Amazing.
jawed moths? that reminded me of mothra in the monsterverse. so mothra was an ancient giant moth after all.
Until flappity-flap went the dracula bat, and that was that.
many kaijus in the monsterverse were based from prehistoric creatures so yeah your right

Great video, I don’t usually see videos on the evolution of insects expect for the “look how big they were” variety. Would be interested in seeing if the evolution of metamorphosis or even molting is fully understood.
Me too that would be so cool
Precisely.
Lack of fossil means lack of spotlights.
This is related to the evolution of wings in insects, you can search the evolution of flight and the metamophosis plays a big part in it
So how big were they?
None of this is true, moths came to be when the lamp evolved.
Truth.
LAMP
The old philosophical question; what came first, the moth or the lamp?
@Pinoy Doler nice
Lämp
I thought many butterfly colors where due to meta-material effects, not pigments. In fact, I’m fairly confident no butterfly has blue pigment, but uses the nano-architecture of the scales to display as blue to observers.
There’s actually a single species of butterfly that produces a truly blue pigment
Structural coloration vs pigment coloration
Butterflies: why not both?
@@noodle714 They used their pigment for dying money.
Source: the book and Steve McQueen/Dustin Hoffman movie "Papillon" - which means "butterfly."
There are some butterflies that do (Most famously Morphos, which is a whole genus) but most use pigments
Moths: LAMP
Butterflies: POLEEN

The thumbnail looks straight from those "how aliens would reconstruct the animal" memes.
Can't argue that lol
i really don't find these representation of Anurognathus pterosaur, i think it's the color
first came the bees? My understanding is that the first pollinating animals were beetle-like (koleoptera) and that their flowers of choice were big and edible. Then came the bees, who were able to pollinate without damaging the flower - which was a considerable evolutionary advantage. This is also the reason that among the most "primitive" flowers are the large magnolias.
Isn't it spelled coleoptera.also interesting thing is some beetles actually had the normal front wings back then too,some still do to this day,although they don't use it for flight....
8:19 imagine waking up in the middle of the night and some critter a third your length is sitting on your face drinking your tears.

Yea the niche will always be filled
Correction: First came the beetles and flies as flower pollinators. Many angiosperms are older than hymenoptera and lepidoptera, like Magoliaceae, Nympheacea and Annonaceae. This leaves Diptera and Coleoptera as most likely original pollinators of the oldest flowering plants. The oldest extant angiosperms are clearly evolved to attract beetles and flies.
Not anymore. The whole crux of the recent discoveries discussed in the video is that Lepidoptera were already around during the earliest Jurassic and were pre-adapted for the evolution of flowers later in the Mesozoic. Additionally, the hymenopteran fossil record now extends into the Late Triassic.
@@Ozraptor4 I haven't disagreed with the evidence in this video, and thought it was great, however a dearth of evidence leaves quite a bit of mystery around what came first, pollinators or flowers, or that they drove one another's evolution. I listened carefully to the video, nothing mentioned suggests that lepidoptera or hymenoptera predate Cleoptera or diptera as pollinators, in fact this matter was not even duacussed. And again, the oldest of flowering forms, are clearly designed for cantharphily, beetle pollination. You can see it if you know flowers well. Look at magnolias, one of the oldest of floweing families for example, no butterfly will land in its bowl shaped flower, and bees rarely visit. If one looks one will find magnolia flowers filled with beetles. Think on the morphology of flowers, bees use flowers that fit their bodies, butterflies too. Butterflies cannot use many flowers, they need something to land on. The kinds of flowers butterflies and bees use were not the oldest flowers, but instead we find the oldest flowering plants attract beetles and flies and are designed to encourage their help in pollination. It does seem, though that it was the diversification of both hymenoptera and lepidoptera that was the impetus behind the later rapid diversification of angiosperms, the beetles never really adapted further in this regard.
The Coleoptera, beetles, were in fact the original pollinators. That’s one of the many reasons that this order is one of the most diverse in the whole animal kingdom, as they evolved along side the angiosperms.
I create angiosperm everyday
Neat thank you for the learnings
Damn your channel has exploded, I remember when you had 10k subs and 4 patreons. Now you have a giant list, a massive sub account and your videos have only increased in quality. Good job

I was literally wondering about the evolution of butterflies just yesterday, after watching one of your videos, and I'm so glad you answered the call of my curious heart!
Nice to see a moth & butterfly topic, they don't get much notice on insect-related videos
Scaled Wing*
Not scaled insects
Lepidoptera
Just like a pterosaur is a winged lizard. (Even thought it wasnt a lizard.)
Easy mistake to make, I guess, since every insect order is something-ptera

Been binge watching your vids the past week, first video I've seen close after it's been posted. Anyways, love the videos and I think you'll get bigger given that I personally was just recommended your channel out of the blue and hadn't searched for any topic you've covered, so it appears the algorithm favors you!
His speak is just sooo nice! 🥰
Same here with him randomly showing up in my recommended. I'm happy the algorithm favors him. Great channel
4:50 wait, if butterflies adapeted to take advanagte of flowers as a food source wouldnt they have developed eyes to see colorful flowers first and then started to develop elaborate patterns for sexual display as their eyes became specialized for finding flowers?
I would assume they use smell over sight for flower nectar.
@@neptunestreaming4261 In many lepidoptera only the males have a very keen sense smell
As far as I know, the first flowers weren't very colourful, so their eyes didn't need to be all that well adapted in the beginning. The first flower colours were white and yellow, which would have looked bright and clear enough against green leaves.
I'm guessing that an accumulation of mutations in eye structure allowed them to see differing colours as flowers also began to evolve and mutate new colours.
Fascinating stuff, well presented. Would love to see some more about evolution of insects and other small invertebrates
If lepidopterans had ears before bats evolved, it makes me wonder what noises pterosaurs made...
They were terribly rude. Where were their parents?
WRYYYYYY

Take a shot every time he says something like, "It was thought that (feature) evolved because of (x), but as it turns out it was actually discovered much earlier, probably due to (y)."

Moth 1: I use my highly developed mouth tool to drink the tears of my enemies, while they rest beneath the silent moon
Moth 2: hehe animal poo
Me: Moths have ears and a proboscis?
Moths: This is what it sounds like when doves cry.
Your videos are always interesting you do great job congratulations
So you're telling me I could potentially scream at a moth and startle it.
Dang I thought this was gunna have more of a focus on how a process like metamorphosis could evolve. Seems impossible to imagine how that evolves incrementally
Just remember, the magic in evolution is time. An intricate body part such as eyes evolved multiple times? Just add more time, time fixes everything.
Im really glad ur channel is getting big I’ve been a fan for awhile so it’s nice to see a UA-camr growing.
Moth Light Media: is referred to the way moths are attracted to light so in essence the content of this channel is the “light” that attracts viewers “moths” and the media portion is just as described. That’s why it’s called Moth Light Media! Or, at least, that’s my interpretation of it.
This was wonderful! I learned a lot of things I never suspected, and they will enrich my experience in watching moths and butterflies from now on. Thank you.
Thank you so much for your work, i really enjoy your content. Keep up the good work my friend
Being Entomophobic, and still watching this, is a proof of strength
Wooo! Good job! I am impressed with your show of mental strength to watch a video about something you’re terrified of to that extent. Well done.
@@labaccident2010 Thanks, I hope that one day I'll be able to fully get rid of my fear.
But for now, I'm stuck at avoiding those creatures of Hell
@@DAVINNIA314 Maybe someday, but being able to watch a video of them successfully is a massive first step!
@@labaccident2010 I was totally terrified while watching it, but at least I tried
@@DAVINNIA314 Exactly- you tried anyway.
Thank you for your videos. They are very interesting and I've learned a lot from them.
I like moths. They are fluffy and cute.
Super cool! I thought one of the reasons Lepidoptera evolved wing scales was because it allows them to escape spider webs- the scales stay stuck to the web while the creature itself is able to fly away.
love your videos man! keep up the good work!
Holy cow I remember when this video first came out and thought the art was so neat. Just came across it again but forgot I watched it. Very nice work.
Bin here since 2k Buddy, Proud of ur channel growing
I love learning about insect evolution plz make more vids like this :3
Amazing video! I loved it. Your content could be used as really powerful educational resource, specially in this pandemic days were students away from schools.
Great video, would love to see another one on insects and there origins
Keep ’em comin’! I can't get enough
what a great video, I never would have researched any of this on my own, and it's fascinating to think that animals so common were once an intrusive newcomer. I guess you had to do a moth video eventually, considering your channel's name...
good thing i have notifications on
its good to learn about the common things you see in everyday life.
I can’t stop thinking about that one episode of spongebob where he was freaking out over a butterfly.
Moth: I only drink the tears of my enemies
Fantastic. Not only paleontology but great current species pics and video.
Doesn't "lepidoptera" mean "scaled wings" rather than "scaled insect?"
Binge-watching. Such interesting subjects, well narrated and illustrated. Thanks!
wow days ago i was actually thinking how Butterflies evolve to what they're today, and now i see this ❤️
This channel is better and more informative than anything I ever did at school.....mmmmh, you don’t know what you wanted till you see it.
Thank you for this video keep up the good work❤👌👍
Wow these videos are AMAZING.
This is some prime content, I had no idea that jawed moths were even a thing
That video of a butterfly cleaning itself is my new favourite thing
Why is it impossible that before the appearance of modern flowers a whole other world of gymnosperm false flowers existed with other types of pollinating insects? After all, many modern gymnosperms have structures equivalent to the flowers and use insects.
I read that the cycads might have been pollinated by ancient relatives of scorpionflies
Well considered.
Great front cover piece for your channels namesake, and not ironically, quite illuminating on Lepidoptera.
This was awesome, thank you.
Very good channel.
No bullshit gimmicks, just good, dry information.
Some of us hate on moths when they're the ancestors of the butterflies everyone loves. Show moths some respect!
Angiosperms have been dated at ~175 Million years ago by recent analysis. So they appeared during the Jurassic, not the Cretaceous.
Brilliantly interesting video!
I remember when I would catch butterflies and yeet them back into mother nature's hands. It was beautiful TwT.
Very interesting thank you for the videos xx
Came for the butterflies, stayed for the tear drinking moths. BRB, got some fossilized memes to bring back.
Fascinating topic. Thanks :)
Your channel name: moth light media
This video: moths.

Congratulations, you can read. Want a medal?
Moths are cute and fluffy, they have colourful wings, and they love to DRINK THE TEARS OF THEIR ENEMIES
Amazing quality channel
you really need to publish this verbatim as a children's picture book with illustrations. maybe watercolor. you already have the audio book ready ! i say this because i use this video to put myself to sleep at least once or twice a week. I've never found a more reliable barbiturate in my entire life. i full suffer from life long insomnia and child me would have loved this. the lofty scholarly jargon should be left in-tact, as well as the broad and vague way contradictions are introduced then brushed aside. a story with almost no conflict of opinion is rare in the paleontology world. and opening your eyes every few seconds just to see b roll of butterflies or moths or bats or birds or flowers? excellent.
I love your videos- one that i'd be very interested to see is the evolution of owls
The moth at 6:50 looks more stuck in the 70s than in 150,000,000BC. Some very primitive members of the group never lost the Disco I guess. It even has a Mohawk.
Exactly what I was thinking. Only instead of lamps, they swarmed disco balls.
Great video. Really useful information. I work in conservation and will share. 👍
And now lepidoptera is even more fascinating than I gave them credit for
Great video - equally interesting is contemplating how the complete metamorphosis phenomena in insects (which caterpillar/lava to adult process is so sublime and beautiful in butterflies) originally may have arisen in primitive insects.
Thank you so much for focusing on other topics, besides dinosaurs, in Paleo!!!
You should have mentioned the hummingbird moth and the hawk moth family. It took me 46 years to see my first hummingbird moth.
Beautiful video.
I was intrigued by the Micropterigidae and it made me wonder what adult moths of that genus eat, as it may be similar to what the ancestral forms ate before the proboscis evolved. It seems they have a fondness for spores of ferns and other lower plants. I imagine some of their ancestors had a similar life style, although possibly some were predatory like their Caddisfly cousins or maybe didn't even eat at all as adults.
most relaxing videos ever
As a guy studying biology and hopefully getting a horticulture master's one day.... any vid about pollinators is a must watch
great video
The evolution of butterflies!!!! Really!!!! Are you trying to seduce me? Fabulous content, absolutely superb.
