Pylogeny and evolution of diet of the Scarabaeoidea

金龟子总科对土壤、腐木、腐肉、其他动物遗骸、活植物根、腐殖土和粪便等各种食物资源表现出显著的适应性。有些群体与社会性昆虫有联系。关于金龟子总科食性的起源和演化，人们提出了各种假说，但大多数假说都是直观的或肤浅的，没有系统发育数据。在本研究中，我使用了形态学和分子技术的代表性群体，以提高系统发育的估计。根据所建系统发育树，还讨论了金龟子总科食性的演化。

The superfamily Scarabaeoidea shows remarkable adaptations to various food resources such as soil, rotting wood, carrion, other animal remains, living plant roots, humus and dung. Some groups are associating with social insects. Various hypotheses have been proposed about the possible origins and evolution of feeding habits in the Scarabaeoidea, but most of them were intuitive or superficial and without phylogenetic data. In the present study, I used both the morphological and molecular techniques for the representative groups in order to improve phylogenetic estimates. Based on the suggested phylogenetic trees, I also discussed the evolution of feeding habits of the superfamily Scarabaeoidea.
