Trait exaggeration, well known to naturalists and evolutionary biologists, has recently become a prominent research subject in the modern field of Evolutionary Developmental Biology. A large number of traits that can be considered as cases of exaggeration exist in nature. Yet, the field has almost exclusively focused on the study of growth-related exaggerated traits in a selection of holometabolous insects. The absence of the hemimetabola from studies of exaggeration leaves a significant gap in our understanding of the development and evolution of such traits. Here we argue that efforts to understand the mechanisms of trait exaggeration would benefit from expanding the study subjects to include other kinds of exaggeration and other model species.
性状夸张现象，博物学家和进化生物学家都熟知，最近已成为现代进化发育生物学领域的一个突出研究课题。自然界中存在大量可被视为夸张实例的性状。然而，该领域几乎完全专注于对全变态昆虫中与生长相关的夸张性状的研究。半变态昆虫在夸张研究中缺失，这在我们对这类性状的发育和进化的理解上留下了重大空白。在此我们认为，将研究对象扩展到包括其他类型的夸张和其他模式物种，将有助于理解性状夸张的机制。
