Intrataxonomic differences in terms of angiosperm suitability for herbivorous insects stem from variables such as plant structure, palatability, and chemistry. It has not yet been elucidated whether these differences also occur in terms of the bryophyte's suitability to bryophages. Hedw. is a morphologically variable moss species frequently inhabited or fed by insects. In this investigation, we offered five morphotypes of to two bryophagous species of Byrrhidae (Coleoptera) to reveal whether the intrataxonomic variability affects beetles' preferences. The morphotypes were offered with preserved and removed spatial structures. There were no significant differences in morphotype preferences when spatial structures were preserved, although during the daytime, the beetles moved from the morphotype to the and morphotypes. The beetles preferred the morphotype when the spatial structures were removed. The results suggest that the spatial structure variations in the complex are accompanied by different chemical, physiological, or microscopic morphological profiles that are recognized by the bryophagous insects. Phylogenetic and epigenetic analyses can reveal multiple differences within the complex. Their interconnection with information about the preferences of bryophagous insects can help us to elucidate which of these differences are ecologically relevant.
被子植物对食草昆虫的适宜性在分类学内部的差异源于植物结构、适口性和化学组成等变量。苔藓植物对苔藓食性昆虫的适宜性方面是否也存在这些差异，目前尚未阐明。Hedw.是一种形态多变的苔藓物种，经常有昆虫栖息或取食。在本研究中，我们将Hedw.的五种形态型提供给两种隐翅虫科（鞘翅目）的苔藓食性物种，以揭示分类学内部的变异性是否会影响甲虫的偏好。这些形态型提供了保留和去除空间结构的情况。当保留空间结构时，形态型偏好没有显著差异，尽管在白天，甲虫会从Hedw.的一种形态型转移到另一种形态型。当去除空间结构时，甲虫更喜欢某一种形态型。结果表明，Hedw.复合体中的空间结构变化伴随着不同的化学、生理或微观形态特征，这些特征能被苔藓食性昆虫识别。系统发育和表观遗传学分析可以揭示Hedw.复合体内的多种差异。它们与苔藓食性昆虫偏好信息的相互联系可以帮助我们阐明这些差异中哪些在生态上是相关的。
