Praying Mantis Love is Waaay Weirder Than You Think | Deep Look

This episode of Deep Look is brought to you
by Curiosity Stream. This mantis is at the top of her game. All summer, she’s been bulking up on grasshoppers
and flies. They’re called bordered mantises. Ambush hunters, cloaked by camouflage – some
green and some brown. And check out those forelimbs… they’re
lined with sharp spikes – almost like a couple extra sets of jaws to grab her prey. They’ve served her well. But summer is coming to an end here in California’s
Owens Valley. The one thing left for them to do is start
the next generation. She sends out a chemical signal – an alluring
cocktail of pheromones – into the air. This guy picks up the message. He’s way, way smaller than she is – simply
outclassed when it comes to strength and deadliness. He makes his move, to pass on his genes for Uhhh… That’s one way to go. And he’s not the only male to meet his end
this way. So why would praying mantises do this – eat
their own kind at a rather intimate moment? Seems like they wouldn’t last long as a
species. Well, it takes a ton of energy for females
to produce their eggs – about a hundred of them, developing inside her. She’ll lay them in a foamy cluster like
this called an ootheca. So that male is fueling the survival of his
species, nutritionally-speaking. When they hatch in the spring, there will
be plenty more mantises to replace this one. And these bordered mantises weren’t going
to live much longer anyway. They can’t survive the cold autumn nights. So males might as well take a shot. Aww… this time it worked out. He delivers a packet of sperm to fertilize
her eggs. But each time, it’s a serious gamble. Well, that didn’t go so well. But wait, look… He’s been decapitated, but his body is still
moving Like it’s on autopilot – kind of a zombie
mating machine. It’s being controlled by nerves in the mantis’
abdomen and can still… get the job done. In fact, males who successfully mate and get
eaten in the process may father more eggs than those who get away. So, while it may not really seem that way,
this guy may be the ultimate winner in the primal quest to pass on his genes. This episode is brought to you by Curiosity

  1. Imagine you grew up as a male mantis and when you were a kid you were told by your mum son…….. Your gonna be EATEN

  2. I've always loved mantids the most of all bugs. One of my earliest memories is seeing a huge green one hanging out on a garage lock and my mom, bless her, told my 4 year old self the females eat the males after they've finished mating. I was horrified and fascinated. Also, compared to many other bugs, mantids seem like they're aware of you. I've had one look at me and come over to me from 3-4 feet away until it could've hopped on me. But I was done with my smoke break so I had to go and ruin the magic moment.

    It's mating season here in the mojave and out on my front porch are two smol males trying to get their freak on with a big female. Good luck, fellas

  3. Nature hates men Nature hates men nature hates men nature hates men nature hates men nature hates men nature hates men nature hates men nature hates men nature hates men nature hates men

  4. This really should be narrated with more of a horror tone lol This happy go lucky style does not fit the disturbing imagery!
    Imagine this thing if it was only a couple feet bigger!! This would be such a nightmare! I pity all bugs.

  5. @3:55 wait why? They didn't explain this statement at all. If a male praying mantis got to mate with a female and not get eaten, could he possibly mate with another female and spread more of his genes? Wouldn't getting each eliminate that possibility?

  6. They're really no different than humans. Human women just choose to kill their partners over the course of several decades.

  7. Thanks for explaining what's going on on my front porch because she's huge and obviously female and he's looking for love. Our Black Widows here are enjoying the video, so thanks for the upload. 😉

  8. I thought everyone knew this, that's why I clicked on this title, Mantis love is way weirder than you think.
    This is nothing new that I didn't learn in science class in 9th grade. NUM NUM NUMS MMMMM GOOD.
