寄生蝇科是一个物种丰富且分布广泛的寄生蝇科，有超过250属，分为17个现存亚科。然而，人们对它们的进化历史或它们今天的多样性是如何形成的知之甚少。利用15种蜂蝇的转录组和86种蜂蝇14亚科94种的锚定杂交富集序列（AHE），重建了蜂蝇科的系统发育。我们整合了来自AHE树中每个主要谱系的转录组的数据，以构建具有更多基因（550个位点对216个位点）和更高支持水平的数据集。我们的总体结果显示出强烈的一致性与目前的家庭的分类，14个包括亚科恢复为单系的11。Heterotropinae和Mythicomyiinae是该科其余成员的连续姐妹群。我们通过我们的系统发育假说研究了关键形态特征的演变，并表明，无论是“砂室亚科”，也不是“Tomophthalmae”是单系在我们的基因组分析。根据我们的研究结果，我们恢复两个部落在亚科水平（Phthiriinae统计。和Ecliminae stat.修订）我们将丝尾蜂属（Sericosoma Macquart）（以前称为无角丝尾蜂属（incertae sedis））归入蜂蝇亚科（Oniromyiinae），使蜂蝇亚科总数达到19个。我们的测年分析表明，该家族起源于侏罗纪（165-194 Ma），砂室在蜜蜂进化的早期，在侏罗纪晚期或白垩纪中期（100-165 Ma）。我们推测，被子植物辐射和温室气候建立在白垩纪晚期加速蜜蜂苍蝇的多样化，通过提供一个扩大的范围内的寄生虫幼虫和蜜源成虫的资源。
Bombyliidae is a very species‐rich and widespread family of parasitoid flies with more than 250 genera classified into 17 extant subfamilies. However, little is known about their evolutionary history or how their present‐day diversity was shaped. Transcriptomes of 15 species and anchored hybrid enrichment (AHE) sequence captures of 86 species, representing 94 bee fly species and 14 subfamilies, were used to reconstruct the phylogeny of Bombyliidae. We integrated data from transcriptomes across each of the main lineages in our AHE tree to build a data set with more genes (550 loci versus 216 loci) and higher support levels. Our overall results show strong congruence with the current classification of the family, with 11 out of 14 included subfamilies recovered as monophyletic. Heterotropinae and Mythicomyiinae are successive sister groups to the remainder of the family. We examined the evolution of key morphological characters through our phylogenetic hypotheses and show that neither the “sand chamber subfamilies” nor the “Tomophthalmae” are monophyletic in our phylogenomic analyses. Based on our results, we reinstate two tribes at the subfamily level (Phthiriinae stat. rev. and Ecliminae stat. rev.) and we include the genus Sericosoma Macquart (previously incertae sedis) in the subfamily Oniromyiinae, bringing the total number of bee fly subfamilies to 19. Our dating analyses indicate a Jurassic origin of the family (165–194 Ma), with the sand chamber evolving early in bee fly evolution, in the late Jurassic or mid‐Cretaceous (100–165 Ma). We hypothesize that the angiosperm radiation and the hothouse climate established during the late Cretaceous accelerated the diversification of bee flies, by providing an expanded range of resources for the parasitoid larvae and nectarivorous adults.
