传粉昆虫在被子植物的起源和早期进化中起着决定性的作用。在辽宁省中国东北部晚侏罗世岩石中发现的传粉短角类化石(短角蝇)，为被子植物起源于前白垩纪提供了证据。功能形态和与现代同科类群的比较表明，Orthhaphous Brachycera是最古老的传粉者之一，这些数据表明被子植物起源于晚侏罗世，至少有两种花类型。
Pollinating insects played a decisive role in the origin and early evolution of the angiosperms. Pollinating orthorrhaphous Brachycera fossils (short-horned flies) collected from Late Jurassic rocks in Liaoning Province of northeast China provide evidence for a pre-Cretaceous origin of angiosperms. Functional morphology and comparison with modern confamilial taxa show that the orthorrhaphous Brachycera were some of the most ancient pollinators, These data thus imply that angiosperms originated during the Late Jurassic and were represented by at least two floral types.
