An evolutionary strategy in which an animal adopts a display designed to scare off a predator. For example, the caterpillar of the hawkmoth (Leucorampha sp.) normally rests upside down beneath a branch or leaf. When disturbed, it raises and inflates its head, the ventral surface of which has conspicuous eye-like marks, and the general patterning of which resembles the head of a snake. Many moths and butterflies have eye-spots on their wings, which they reveal suddenly when disturbed, with the possible effect of frightening the predator.
