Have you created many insect farms?

The first video is indeed what I saw. I watched it on TV though. I think it was on Animal Planet.
Those Hornets have such armor that make them immune to bee stings. It's funny how in the video they call it "Asian invaders" massacring "European" bees.

I was surprised by the second video. That Black Widow spider was dumb not to bite the mantis from the rear when it had the chance. The mantis was caught in the web, which made it a sitting duck. I really thought the spider was going to win, consider a single bite from black widow could have killed a human.

Third video surprised me too. Are you sure it's a honey bee? Mantis is the predator here, but it seems the honey bee kept on biting.
