This Plant Summons An Ant Army By Bleeding Nectar When Wounded

  • Plants aren't always the innocent, harmless eye-candy we might think they are - the Venus flytrap is proof of that.
    And researchers from the Free University of Berlin just added another sinister plant to the list: the bittersweet nightshade plant.
    When the plant is wounded by herbivores or insects gnawing on its leaves, it effectively bleeds a sweet nectar that attracts ants. Those lured ants send encroaching leaf-eaters scurrying by biting and attacking them.
    And because the "sweet blood" isn't linked to any other structures or functions of the nightshade, the researchers can confidently conclude attracting an ant army isn't some sort of beneficial side-effect - it's probably the whole reason the plant bleeds nectar.
    To be clear, scientists have long observed other plants that basically create bug armies by luring them in with nectar or giving them shelter. But plant wounds that attract an ant army? That's new.

    Can you guys provide references to the research at the end of your videos/in their descriptions?

      "researchers at University X at location Y" isn't much of a reference

      No references, because they are all lies. No fact, and certainly not based on peer-reviewed research. Notice how this channel is non-operational, now. No new videos, for over 8 months. They've been busted for spreading disinformation, is my bet.
