Of course, if you actually read the article, it gets a lot more gruesome.
A species of moth drinks tears from the eyes of sleeping birds using a fearsome proboscis shaped like a harpoon, scientists have revealed. The new discovery – spied in Madagascar – is the first time moths have been seen feeding on the tears of birds.
But sleeping birds have two eyelids, both closed. So instead of the soft, straw-like mouthparts found on tear-drinking moths elsewhere, the Madagascan moth has a proboscis with hooks and barbs “shaped like an ancient harpoon”, Hilgartner says. This can be inserted under the bird’s eyelids, where the barbs anchor it, apparently without disturbing the bird.
