伪装描述了一个生物体与一个不可食用的物体的相似之处，并被假设为促进捕食者或猎物对该生物体的错误识别。到目前为止，还没有实证证明化妆舞会的好处。在这里，我们表明，两种毛毛虫获得保护鸟类捕食者被误认为树枝。通过操纵捕食者以前对假定模型的经验，但保持他们对伪装者的暴露相同，我们确定捕食者错误地将伪装的猎物识别为他们的模型，而不是简单地没有发现它们。
Masquerade describes the resemblance of an organism to an inedible object and is hypothesized to facilitate misidentification of that organism by its predators or its prey. To date, there has been no empirical demonstration of the benefits of masquerade. Here, we show that two species of caterpillar obtain protection from an avian predator by being misidentified as twigs. By manipulating predators’ previous experience of the putative model but keeping their exposure to the masquerader the same, we determined that predators misidentify masquerading prey as their models, rather than simply failing to detect them.
