New Scientist magazine is reporting that a Madagascar moth has been discovered drinking the tears of sleeping birds. The phenomenon isn't totally unheard of as other species of moths tend to drink the tears of other, larger creatures (like crocodile, deer, and other animals that can't brush them away). This is the first time, however, that the insects have been monitored not only drinking the tears of birds-- for salt, apparently-- but also using their strange harpoon like tongues to anchor and pry open a sleeping bird's eye. What's most fascinating, is that the bird doesn't seem to know what's happening, leading scientists to question whether the moths are using an anaesthetic as part of their operation.
