[@Zaxares]

One additional interesting fact that ZeFrank didn't mention in this video is that the carpenter ants can actually tell if one of their own is infected. If a worker finds an infected ant, it will grab the infected ant and carry it out of the hive as far away as possible before abandoning the doomed ant to its fate. (The worker that does this is still safe because the cordyceps fungus is not yet in its fruiting stage, so the infectious spores have not emerged yet.) Despite these precautions though, wind can still carry the spores back and infect more ants.

[@jynxed66six54]

the problem is this. even if you can prove the spores dont produce it themselves, its impossible to know if the spores are making the fly do it themselves. in which case, it would still be the spores doing it.

[@gagemal5]

It might but In the science world that is still an educated guess even if I’d had the same chemical makeup. Just because it matches the chemical profile doesn’t mean the fly didn’t make it because the fungus could just override the flys organs and use them to produce the adhesive according to the fungus’ blueprints which would mimic the chemical makeup of the fungus adhesive. Furthermore if they matched it would be like ok maybe the fungus is making it not entirely sure though. And if they didn’t match it wouldn’t mean anything at all. Because the fungus could simply use a new compound for sticking a fly to a leaf one that is wholly different from the spore sticking compound. Great thought, but this is just a complicated question you’re definitely on the right track though!!!

This is by far the most disturbing video you’ve done, and that includes the spider one. Edit: Any alien species that witnessed these fungi would either run screaming or burn us from orbit.

[@tricursor2481]

Genuinely this is the best video I've seen on parasitic fungi. I've always found them so fascinating and wanted to know how it actually does it what it does. This is the first video I've seen to explore that aspect (the brain on the fly and mandible muscles on the ant) and i love it. You've been making videos for over a decade and they've been entertaining me since I was in high school. Ive always been a big nerd constantly wanting to learn, but you should know that your humor mixed in with teaching made dozens of kids at my school watch your videos religiously and of course, caused the random days in biology where half of the class was able to answer questions and give fun facts about a subject they learned in your videos. I hope you realize the impact you've had on society.

I doubt it would give the same results. After all, a mammal nervous system, immune system, and just general biochemistry work quite differently from arthropods. It could cause quite the nasty rash though, or maybe pneumonia or digestive distress. Imagine dying of explosive diarrhea because you caught an ant fungus. What a way to go.

[@spackerinternational6131]

You forgot an important step. Once a spore first 'hatches' it is a monokaryon. It needs to find another compatible spore that's hatched and bind with to form a dikykaryon. They share genetic information and produce the mycelium that is the new fungi. Then it begins to consume materials. It's the same as humans mating but instead the sperm and egg find each other outside of the body.

[@CL-go2ji]

Wild.

[@brightmoon7132]

Since this summer is supposed to be a cicadageddon because 2 broods, 13 and 17 year, are both emerging at the same time, I am definitely rooting for the fungus. The bug science hippies are saying there will be up to a trillion cicadas in circulation. Just one cicada can create noise up to 120 decibels, which is loud enough to permanently damage human hearing. I don't even want to think about hundreds of thousands of them will sound like. So, GO FUNGUS!

[@normalhuman9878]

My area seems to have avoided the double emergence event. The woods are actually pretty quiet and I’m honestly a little disappointed because I’m a wannabe hippie scientist

[@Th3EpitapH]

For shots like the spore cannon ones, it'd be really helpful to have a "1x / 4x/ 0.25x-speed" indicator, for however fast the footage is. With the way small things move, it can be extremely hard to tell how fast any playback is, and it's a big bit of perspective that's missing. Same for shots of moving microorganisms, like the plant cell wall being breached.

[@Imberis]

This is fascinating and now I'm horrified to learn that fungi can tell time.

[@migitri]

There are some non-fungal pathogens that affect insects and other arthropods that I think are interesting too. One is the horsehair worms, which infect various arthropods, including some insects and some crustaceans. There are many species, and I believe each one specializes in a different host. It hijacks its host's brain, makes it find water and drown itself, and then the worm comes out of the arthropod's butt to begin the cycle again. I first learned about these a little over a decade ago when I had to identify one after one of my cats brought one inside and was playing with it. It was wriggling all around. Thankfully it's only dangerous to arthropods. My kitty did not become a zombie. Another is a virus that infects caterpillars. It's called baculovirus. It makes the caterpillar climb high into a tree, then decay and drip down on leaves below to be eaten by other caterpillars. Nature is brutal.

I have to offer sincere praise for another upload made no less remarkable by the consistent quality of your channel. Over the years the focus has changed from merely trying to get a laugh (and usually succeeding) to a humorous but legitimate inquiry into the remarkable forms and mechanisms living creatures make use of. Despite the obvious rigor of your research and the exhaustive effort required for the polish that has become a calling card of your uploads you somehow still never fail to make me chuckle. Consider this a long-winded thank you and congratulations for all you have achieved and contributed to the medium in the last decade or more, and I speak here to the editors, the writers, the researchers and collaborators who are the channel as much as the man himself.

[@Atoll-ok1zm]

I knew a guy in highschool who used to rip the wings off of flys. You take the wings off one side, you get a spin. You take them all off, you get a walk. And if you rip the legs off of a spider, you get a roll.

[@katschs3965]

Ze, I don’t know if you are old enough to remember the Fractured Fairy Tales segments on the Rocky and Bullwinkle cartoon show (NBC, 1959-1964). Watching one on KZbin recently made me realize why your voice sounds so familiar. The narration for the cartoon was done by Edward Everett Horton. His style, word choice, and cadence remind me of you. He also slips in humor clearly intended for the adults in the room, plus groan-worthy puns. Thank you for your informative videos and countless ear-tickles.

Ze was born in `72, so he probably saw the re-runs. I saw the re-runs in the late sixties/early seventies.
