花和传粉者的共同进化是众所周知的，但是通才传粉者如何在不同的环境和花种中识别合适的花还没有很好的理解。在地球仪上随处可见的食蚜蝇是继蜜蜂和大黄蜂之后最重要的替代传粉者之一。在这里，我们测量，预测，并最终重新创建多模态线索从个体花在三个不同的环境（半北，高山和热带）的食蚜蝇访问。我们发现，虽然“花的签名”是独特的每一个环境，一些线索是无处不在的吸引力，尽管不像线索组合从真实的花。我们的研究结果提供了独特的见解，一个世界性的传粉者如何识别不同环境中的花对象，这对我们理解授粉作为一种全球生态服务具有重要意义。超过80%的开花植物物种专门用于动物授粉，了解野生传粉者如何利用环境中的资源可以鼓励有效的种植和维护策略，以最大限度地提高授粉效果，并在面对环境变化时建立适应能力。一个基本的问题是通才传粉者如何在截然不同的生态和环境中识别“花对象”。一方面，传粉者可以采用一套特定的花卉线索，而不管环境如何。或者，野生传粉者可以识别每个环境或花卉物种独特的线索的独家签名。在地球仪上随处可见的蜻蜓是继蜜蜂和熊蜂之后最重要的生态传粉者之一。在这里，我们利用它们的世界性地位来了解野生传粉者的偏好如何在不同大陆发生变化。没有采用任何先验的假设有关的花的线索，我们测量，预测，并最终人工重建的多式联运线索，从个人花访问的hoverflies在三个不同的环境（半寒带，高山，热带）使用基于字段的方法。我们发现，虽然“花的签名”是独特的每一个环境，一些多式联运诱惑无处不在的吸引力，尽管没有携带任何奖励，或类似于真实的花。虽然出乎意料的是，在真实的花中发现的线索组合是不必要的，但我们的诱饵在昆虫物种和生态中的稳健性可以反映通才传粉者资源识别的一般策略。我们的研究结果提供了深入了解世界性的传粉者，如食蚜蝇，如何识别花朵，并提供特定的生态为基础的线索和策略，吸引传粉者在不同的环境。
The coeveolution of flowers and pollinators is well known, but how generalist pollinators identify suitable flowers across environments and flower species is not well understood. Hoverflies, which are found across the globe, are one of the most important alternative pollinators after bees and bumblebees. Here we measured, predicted, and finally recreated multimodal cues from individual flowers visited by hoverflies in three different environments (hemiboreal, alpine, and tropical). We found that although “flower signatures” were unique for each environment, some cues were ubiquitously attractive, despite not resembling cue combinations from real flowers. Our results provide unique insights into how a cosmopolitan pollinator identifies flower objects across environments, which has important implications for our understanding of pollination as a global ecological service. With more than 80% of flowering plant species specialized for animal pollination, understanding how wild pollinators utilize resources across environments can encourage efficient planting and maintenance strategies to maximize pollination and establish resilience in the face of environmental change. A fundamental question is how generalist pollinators recognize “flower objects” in vastly different ecologies and environments. On one hand, pollinators could employ a specific set of floral cues regardless of environment. Alternatively, wild pollinators could recognize an exclusive signature of cues unique to each environment or flower species. Hoverflies, which are found across the globe, are one of the most ecologically important alternative pollinators after bees and bumblebees. Here, we have exploited their cosmopolitan status to understand how wild pollinator preferences change across different continents. Without employing any a priori assumptions concerning the floral cues, we measured, predicted, and finally artificially recreated multimodal cues from individual flowers visited by hoverflies in three different environments (hemiboreal, alpine, and tropical) using a field-based methodology. We found that although “flower signatures” were unique for each environment, some multimodal lures were ubiquitously attractive, despite not carrying any reward, or resembling real flowers. While it was unexpected that cue combinations found in real flowers were not necessary, the robustness of our lures across insect species and ecologies could reflect a general strategy of resource identification for generalist pollinators. Our results provide insights into how cosmopolitan pollinators such as hoverflies identify flowers and offer specific ecologically based cues and strategies for attracting pollinators across diverse environments.
