蝴蝶是一个多样化且富有魅力的昆虫群体，它们被认为是随着植物进化而来的，并随着关键的地质事件而分散到世界各地。然而，这些假设尚未得到广泛检验，因为缺乏全面的系统发育框架和蝴蝶幼虫宿主和全球分布的数据集。我们对来自近 2,300 种蝴蝶的 391 个基因进行了测序，这些蝴蝶来自 90 个国家和 28 个标本收藏，以重建占所有属 92% 的新蝴蝶系统发育树。我们的系统发育对几乎所有节点都有强有力的支持，并表明至少有 36 个蝴蝶部落需要重新分类。发散时间分析表明蝴蝶的起源是 ~1 亿年前，并表明除了一个科之外，所有科在 K/Pg 灭绝事件之前都存在。我们汇总了幼虫宿主数据集和全球分布记录，发现蝴蝶很可能首先以豆科植物为食，起源于现在的美洲。白垩纪热极盛期过后不久，蝴蝶穿越白令山脉，在古热带地区多样化。我们的结果还表明，大多数蝴蝶物种都是仅以一个幼虫寄主植物家族为食的专家。然而，食用两个或多个植物科的通才蝴蝶通常以密切相关的植物为食。

A global phylogeny of butterflies reveals their evolutionary history, ancestral hosts and biogeographic origins
Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are lacking. We sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries and 28 specimen collections, to reconstruct a new phylogenomic tree of butterflies representing 92% of all genera. Our phylogeny has strong support for nearly all nodes and demonstrates that at least 36 butterfly tribes require reclassification. Divergence time analyses imply an origin ~100 million years ago for butterflies and indicate that all but one family were present before the K/Pg extinction event. We aggregated larval host datasets and global distribution records and found that butterflies are likely to have first fed on Fabaceae and originated in what is now the Americas. Soon after the Cretaceous Thermal Maximum, butterflies crossed Beringia and diversified in the Palaeotropics. Our results also reveal that most butterfly species are specialists that feed on only one larval host plant family. However, generalist butterflies that consume two or more plant families usually feed on closely related plants.
