Severe and widespread reductions in nighttime activity of nocturnal moths under modern artificial lighting spectra

Artificial lighting has many negative impacts on nocturnal insects, from harmful phototaxis to disruption of feeding and reproduction. Although comparatively poorly-explored, many detrimental outcomes could be associated with changes in activity. We investigated the effects of different types of light-emitting diode (LED) lighting on activity in multiple wild-caught moth species in three different families. While behaviour under natural conditions varied among species, artificial lighting strongly and largely consistently suppressed activity. In our main experiment, testing 843 moths of 23 species, we found that white LEDs at 10 lx illuminance depressed activity by 85% on average relative to natural nighttime illumination, and even purportedly less harmful amber lighting had similar impacts at the same intensity. There were no differences between the effects of broad-spectrum LEDs and combinations of narrowband LEDs that produce equivalent light for human vision.

## Description of the data and file structure

Last updated: 24/11/2025

Study summary: This study tests the effect of artificial light treatments on activity in multiple species of nocturnal moths. Key analyses for the main experiment include 1) differences in overall activity between control and lit treatments, 2) Bayesian phylogenetic modelling of overall activity across treatments, 3) models testing differences in activity patterns between species in the control conditions, and across species between lighting treatments. In addition, smaller datasets are analysed to test 4) impacts of lower light levels on activity patterns in a smaller number of species, and 5) effects of different capture methods.

All analyses carried out in R v.4.3.2.

人工照明对夜行性昆虫存在诸多负面影响，从有害的趋光行为到觅食与繁殖过程的干扰。尽管相关研究相对匮乏，但活动模式的改变可能同样伴随诸多不利后果。本研究针对隶属于3个不同科的多种野生捕获蛾类，探究了不同类型发光二极管（Light-emitting diode, LED）照明对其活动行为的影响。尽管自然条件下不同物种的行为存在种间差异，但人工照明显著且整体一致地抑制了蛾类活动。在核心实验中，我们对23个物种共843只蛾类开展测试，发现照度为10勒克斯（lx）的白色LED照明相较于自然夜间光照，平均可使蛾类活动水平降低85%；即便被认为危害性更低的琥珀色照明，在相同照度下也产生了相似的抑制效果。广谱LED与可产生等效人眼可视光的窄带LED组合的照明效应并无显著差异。采样方法方面……

研究概述：本研究旨在测试人工光照处理对多种夜行蛾类活动行为的影响。核心实验的关键分析包括：1）对照组与光照处理组的总体活动水平差异；2）不同光照处理下总体活动的贝叶斯系统发育建模；3）用于检验对照组内物种间活动模式差异，以及不同光照处理下物种间活动模式差异的模型。此外，本研究还通过小型数据集开展了两项额外分析：4）低照度光照对少量物种活动模式的影响，以及5）不同采样方法的效应。
所有分析均基于R v.4.3.2版本完成。
