An intriguing entomological experiment shows that a male butterfly will ignore a living female butterfly of his own species in favour of a painted cardboard one, if the cardboard one is big.

Nearby, the real, living female butterfly opens and closes her wings in vain. (Annie Dillard, The Writing Life)
