The wings of the Spanish Moon moth (Graellsia isabellae) bear patterns that look strikingly like eyes. This rare and protected moth, found in Spain and the French Alps, normally rests with its wings folded. When alarmed it spreads them out, revealing a single 5-millimeter wide eyespot on each wing and startling any attacker by its apparent transformation from a moth to the head of a much larger creature. Eyespots are a common defensive device throughout the animal kingdom.
