Abstract A unique form of optical ecological traps is polarised light pollution. Typical sources of this phenomenon is asphalt roads that attract a variety of polarotactic aquatic adult insects seeking horizontally polarised sources recognized as water surfaces. Several harmful effects of polarised light pollution have been previously demonstrated but no quantitative data are available in regard to the loss of a given adult population under these conditions. Our objective was to study the impact of an asphalt road parallel to a creek on the stonefly Perla abdominalis (Guérin-Méneville, 1838). Throughout a three-year study, by comparing the number of exuviae along a stream and the number of adult individuals attracted by the road, we established that 19.6% of the females were trapped by the nearby road. By measuring the reflection–polarisation characteristics of the stream and asphalt surface, we demonstrated that the road may act as attractive, supernormal stimulus for adult females.

量化柏油路的偏振光污染：石蝇的生态陷阱，Perla腹部 (Guérin-Méneville, 1838) (Plecoptera: Perlidae)

摘要 偏振光污染是光学生态陷阱的一种独特形式。这种现象的典型来源是沥青路面，它吸引了各种极性趋向的水生成虫，寻找被认为是水面的水平极化来源。之前已经证明了偏振光污染的几种有害影响，但没有关于在这些条件下特定成年人口损失的定量数据。我们的目标是研究与小溪平行的柏油路对石蝇 Perla腹部的影响 (Guérin-Méneville, 1838)。在为期三年的研究中，通过比较溪流中蜕皮的数量和被道路吸引的成年个体数量，我们确定 19.6% 的雌性被附近的道路困住。
