I Rescued a POTTER WASP, Gained Her Trust... and Filmed Hundreds of PREDATORS Along the WayAdded:
[music] >> Today we'll uncover the mysterious behavior of a potter wasp in captivity, followed by everything I came across along the way, predators, hidden creatures, unexpected encounters, and moments I had never experienced this close before. Get ready because you've never seen anything like this.
Let's get started. This timid little creature flew in through my window, and at first I mistook her for [music] a common wasp. I offered her a little honey, and it was then, watching her up close, that I realized she was something special. This was a potter wasp, an Anterhynchium, a solitary species that seeks shelter in cool, quiet places like the inside of homes to lay her larvae.
>> [music] >> I made sure to provide her with enough water and food in the small container I had set up for her on a temporary basis.
[music] Um something improvised since this was a completely unexpected visit [music] until the time came to take her out to the field and set her free where she belongs. Judging [music] by the way she was eating, she was pretty hungry.
>> [music] >> Unlike other potter wasps that build their mud vessels on walls during the summer, this species does something different. It searches for small holes, and when it finds the right one, it lays its [music] larvae inside. Then it goes out to hunt, paralyzes small worms with its stinger, carries them back to the hole, and then seals [music] the entrance with mud. And just like that, over and over again, this solitary female, with no [music] help from anyone, repeats the same process in every new hole she finds.
Days went [music] by, and that's when I found something strange inside her container. What appeared to be a piece of wing. A puzzling discovery because the wasp was perfectly fine and flew without any issue. So much so that at one point she nearly escaped all across my room.
I had grown fond of her, uh and although she probably hadn't grown fond of me, she had gotten used to my presence.
[music] But the unavoidable moment had come to let her go, to return her to the field where she truly belongs. Along On I stopped to look at an abandoned barrel and found a lizard trapped inside with no way out. It was very lucky that I decided to take a closer look. That's when I realized something surprising. I didn't need to go anywhere to film strange creatures. [music] The ground beneath the leaf litter was teeming with hundreds of them.
Pay close attention to this incredible [music] moment. Both of them startled the instant they came face to face. The ground of this forest, the kind [music] anyone would have walked right over without a second glance, that was bursting with life. Every creature with a purpose, a role in a world that never stops moving.
But it wasn't just the ground that was teeming. Harvestmen were crowding the young thistle plants, [music] more than eight on a single plant, and despite their strange appearance, completely harmless.
Just nearby, hidden among thicker plants and bushes, there lay lurked the biggest [music] predators of the area. These spiders are forced to live as neighbors due to the sheer number of them competing for the best hunting ground.
This one, which just caught an insect, is still a juvenile. [music] Its size will multiply tenfold over the coming weeks because this is an Argiope, and even at this size, it already has a brutal instinct. [music] It knows exactly where and how to spin its vertical web to catch its prey.
>> [music] >> It is an excellent pest controller. Its venom is mild to humans, and while its bite is painful, if I decided to pick her up with my bare hands right now, she probably wouldn't do a thing. They simply aren't aggressive. Their chelicerae are small, almost insignificant [music] to us, but for the insects that fall into her web, it is devastating. But pay attention because that shaking movement [music] she just made with her web means she is angry.
It's a warning to the creatures watching her, [music] and the ants are lurking right beside her trying to reach her and steal her prey.
>> [music] >> They are looking for any weak point in the Argiope's web to get closer, but the spider knows all too well about [music] these feared ants, and she will not give them the chance. But, uh while predators dominated the lower areas, >> [music] >> at the highest parts of the plants, a different kind of creature had taken over completely. Herbivores, tireless seekers of that sweet gold that flows [music] through every stem, sap.
A resource so valuable in this ecosystem that many have built their entire lives around it.
I think this jumping spider has spotted me. I wonder what she must be thinking staring [music] right at me.
But, let's keep going because these plants still hide more secrets I want to show you. Spiders that hunt with extreme precision to go completely unnoticed with webs that work like a perfect alarm system able to tell exactly the size of whatever lands on them and whether it's a threat >> [music] >> or a meal.
But, we haven't seen anything yet because if we look a little deeper, we'll find the creatures that truly run this place. [music] Funnel-web spiders, the undisputed rulers of plants and bushes. When one of them decides to build her lair, she doesn't [music] do it with caution. She does it with authority. They are true engineers of silk covering bushes entirely, claiming them as their own, deciding who comes in and who goes out, who lives and who doesn't. Their massive structures are not meant to go unnoticed, quite the opposite. They want [music] one thing and one thing only, to catch as many prey as possible and position themselves evolutionarily above their competitors.
But, I'll let you in on a secret about these spiders. Despite everything, they are quite distrustful, even skittish. If you get close to observe their web and they spot you, they will vanish into their funnel at full speed. [music] And if they have even the slightest doubt that their prey could cause them any trouble, [music] they will simply abandon it to its fate inside their silk maze and disappear.
This small beetle [music] is a display of extreme survival. It tries to escape at all costs. It knows it's in danger, but cannot see the fine threads of silk that have it cornered, [music] invisible to its eyes. It needs to hurry because the spider could come back at any moment.
>> [music] >> While I was filming all of this, something was attacking me. Mosquitoes at this time of year are a true nightmare for anyone venturing into [music] the forest. Here, I'll show you the sheer number of them swarming around me. Absolute hell. And what we have here is the nightmare of every mosquito, a perfect machine built to hunt them down.
Now, I'll show you just how powerful its jaws really are using a prey borrowed from the ants to run the experiment. The dragonfly is one of the most lethal predators in existence. With a hunting success rate of 90%, [music] it outperforms almost every hunter in the animal kingdom. Its compound eyes allow it to see in every direction at once, a perfect machine. I'd better give them their food back and I don't want to get in the way. They spend the entire day hunting anything that touches the ground carrying [music] dying prey and carrion back to their nest keeping the forest clean. While I was filming, a cow was wandering very close to me and behind her creatures that depend on her to survive. Dung beetles arrived as fast as they could building and rolling their balls of dung without wasting a single second.
>> [music] >> And finally, the moment I came here for, setting free the potter wasp I found in my home and had been taking care of ever since. Take care of yourself, little one.
>> [music] >> It was time to head back home. I couldn't stand the mosquitoes a single minute longer.
But then I spotted something among the plants that made me stop, a small abandoned wasp nest. [music] Perhaps knocked down by the wind and judging by its condition, it had been on the ground for a few days because it was almost empty. [music] Without its queen, it had no future, so I decided to pick it up and take it with me to observe it up close and see if there was anything I could do. Once home, most of the chambers were empty. The ants had most likely taken the majority of the larvae, but there was one hardened cell I couldn't identify whether it was pupating or lifeless. I kept it in a jar to observe it for a few days. Whatever happens, I'll show you in the next video. [music] These videos take a lot of time and effort and it would make me really happy if you liked and commented. And if you're into insects, I'll leave another video right here that I know you're going to love.
