昆虫的多样性常常与被子植物的进化有关。然而，大多数报告这种联系的研究都是在草食性昆虫上进行的。目前尚不清楚被子植物的多样化是否也影响了物种丰富的食肉昆虫群体的多样化。在这里，我们调查的时间起源和多样化的刺蜂（Hyplutera：Aculeata）。我们采用贝叶斯马尔可夫链蒙特卡罗放松时钟的方法来估计发散时间为13黄蜂家庭和8个超家庭。分歧的时间是校准与12个化石代表组在不同的血统。我们的研究结果表明，许多现代的刺科起源于白垩纪，并与被子植物的多样化。黄蜂和被子植物的多样化年龄之间的相似性可能是由于早期被子植物森林提供的栖息地复杂性和猎物多样性增加。
Diversification in insects has often been linked to the evolution of angiosperms. The majority of studies reporting this link, however, have been done on herbivorous insects. It remains unclear if the diversification of angiosperms was also influential in the diversification of species-rich, carnivorous insect groups. Here we investigate the timing of the origin and diversification in the stinging wasps (Hymenoptera: Aculeata). We employ a Bayesian Markov chain Monte Carlo relaxed clock approach to estimate divergence times for 13 wasp families and eight superfamilies. Divergence times are calibrated with 12 fossils representing groups in various lineages. Our results indicate that many of the modern aculeate families originated during the Cretaceous and in concert with the diversification of angiosperms. This similarity between diversification ages in wasps and in angiosperms may be due to an increased habitat complexity and prey diversity that early angiosperm forests provided.
