通过引入路灯和其他来源的人工照明，全球大范围的夜间环境正在迅速改变。预计这将影响许多生物体的视觉生态，影响它们的种内和种间相互作用。在这里，我们展示了不同的人造光源对天蛾视觉生态学多个方面的影响，包括它们对授粉花卉信号的感知、种内性信号的潜力以及它们对鸟类捕食者的视觉防御的有效性。光源分为三大类：一些光源阻止使用彩色信号来实现这些行为，另一些光源更接近地模仿自然照明条件，最后一些类型的效果随光强度和信号颜色而变化。我们发现，荧光粉转换 (PC) 琥珀色 LED 照明（通常被认为对夜行性昆虫危害较小）属于第三类破坏性光源，根据距光源的距离和所观察物体的颜色，会对昆虫视觉生态产生不可预测的后果。仅人工照明对天蛾视觉生态的影响就多种多样，因此需要对环境敏感区域的户外照明采取细致入微的方法，采用旨在限制最重要的影响的强度和光谱。夜间人造光是人类改变环境、影响其他物种的生态和行为的主要方式。对夜间活动的天蛾如何在多种光源下看到和被看到进行建模，表明对关键行为有一系列潜在的破坏性影响。
The nighttime environment is being altered rapidly over large areas worldwide through introduction of artificial lighting, from streetlights and other sources. This is predicted to impact the visual ecology of many organisms, affecting both their intra- and interspecific interactions. Here, we show the effects of different artificial light sources on multiple aspects of hawkmoth visual ecology, including their perception of floral signals for pollination, the potential for intraspecific sexual signalling, and the effectiveness of their visual defences against avian predators. Light sources fall into three broad categories: some that prevent use of chromatic signals for these behaviours, others that more closely mimic natural lighting conditions, and, finally, types whose effects vary with light intensity and signal colour. We find that Phosphor Converted (PC) amber LED lighting – often suggested to be less harmful to nocturnal insects – falls into this third disruptive group, with unpredictable consequences for insect visual ecology depending on distance from the light source and the colour of the objects viewed. The diversity of impacts of artificial lighting on hawkmoth visual ecology alone argues for a nuanced approach to outdoor lighting in environmentally sensitive areas, employing intensities and spectra designed to limit those effects of most significant concern. Artificial light at night is a major way in which humans are altering the environment, impacting the ecology and behaviour of other species. Modelling how nocturnal hawkmoths see and are seen under multiple light sources suggests a range of potentially disruptive impacts on key behaviours.
