Do you feel observed? 👁don't worry: this is not a real eye, but one of the two circular spots, called "ocelli", that adorn the wings of the owl butterfly (caligo memnon), widespread in south america.
for some experts these patches would serve to scare lizards and small birds, which are fond of this moth. in fact, this butterfly forms with the wings a figure that recalls the face of a more fearsome owl.
but not everyone agrees: other scholars think that the false eyes are a trick to limit the damage of a predator attack. the latter could be attracted by the wings that even if damaged allow the animal to live anyway. a way to divert predators from the real weak point: the abdomen.
