伪装动物受益于捕食者在区分它们与不可食用的物体（如树枝）时的困难。化妆舞会的功能已经被证明，但它如何与生物的生活史相互作用尚未研究。在这里，我们报告使用比较分析，以测试假设连接化妆舞会的生活史参数。我们构建了一个系统发育树的鳞翅目家庭Geometridae和Drepanidae的英国种，并编制生活史和颜色数据的文献。我们发现，伪装与利用更大的多样性的宿主植物，无论是测量的科或属的数量。我们发现一个正相关关系的身体大小和多食性伪装物种之间，和隐种之间没有关系。在木本寄主植物上主要分布的种类中，伪装种以幼虫越冬的可能性较大，而隐蔽种则以蛹越冬的可能性较大。多型性与多化性在伪装种，但不隐种。两者合计，我们的研究结果表明，伪装必须被视为一种独特的加密策略，因此可以提供洞察这两种防御策略的演变。我们的研究进一步证明了广泛的物种间比较的效用，在研究不同的生活史参数和捕食者-猎物相互作用的感官方面之间的关联。
Masquerading animals benefit from the difficulty that predators have in differentiating them from the inedible objects, such as twigs, that they resemble. The function of masquerade has been demonstrated, but how it interacts with the life history of organisms has not yet been studied. Here, we report the use of comparative analyses to test hypotheses linking masquerade to life-history parameters. We constructed a phylogenetic tree of the British species of the lepidoptera families Geometridae and Drepanidae, and compiled life history and coloration data from the literature. We found that masquerade is associated with the exploitation of a greater diversity of host plants whether measured by the number of families or genera. We found a positive relationship between body size and polyphagy among masquerading species, and no relationship among cryptic species. Among those species predominantly found on woody host plants, masquerading species are more likely to overwinter as larvae while cryptic species mostly overwinter as pupae. Polyphenism was associated with multivoltinism in masquerading species but not cryptic species. Taken together, our results show that masquerade must be viewed as a strategy distinct to crypsis and hence may provide insights into the evolution of both defensive strategies. Our study further demonstrates the utility of broad-scale between-species comparisons in studying associations between diverse life-history parameters and sensory aspects of predator-prey interactions.
