Science for just $15 USD. Summary Each summer, on bridges across the world, mayfly massacres occur. Warm weather prompts these aquatic insects to emerge as short-lived adults that are lured to early deaths by artificial lighting on bridges. Mayflies aren't alone in their fatal attraction to what researchers refer to as ALAN: artificial light at night. Studies from around the globe are finding worrisome impacts on insect mating and abundance, according to a recent special issue of Insect Conservation and Diversity, and may contribute to the "insect apocalypse." Even as they begin to raise the...

SunStar May 06, 2021 IN THE modern world, lighting at night is a necessity. We have street lights and perimeter lights for safety and security on the road and in our homes. There are also decorative lights, neon signs and others. Apart from the moon’s light however, any illumination at night is unnatural and thus bound to have an impact on ecological systems. This was proven by several studies. A team led by the University of Exeter brought together more than 100 studies and found "widespread" impacts of artificial night-time lighting on animals and plants. Changes to animals' ...

The unintended but 'very harmful' effects of artificial light at night on insects Tom Metcalfe © Provided by NBC News With the world on the brink of an "insect apocalypse," scientists have revealed yet another way we may be wreaking havoc on our six-legged friends: light pollution. Two new studies underline the unintended effects on insects of artificial light at night, and add to broader concerns that our understanding of humanity’s impact on nature is still a work in progress. One of the studies describes how a “biblical plague” of grasshoppers in 2019 was drawn to t...

A Firefly's View of the Insect Apocalypse
 Initiatives to Address Light-related Animal Welfare Challenges Published 03-17-21 Image © SukumaFumio for Brilliant Darkness: Hotaru in the Night NEW YORK, March 17, 2021, /CSRwire/ — The Zoological Lighting Institute™ (ZLI) recognizes the publication of an important new study enhancing growing awareness that light pollution is driving the insect apocalypse, a deadly global decline in insect populations that threatens food security and human sustainability in general. ZLI will dedicate a portion of its ZALA Animal Welfare Stations to monitori...

Credit: Sulema Castro/Smithsonian Artificial light at night (ALAN) is a major factor in global insect decline. In a paper published today in Insect Conservation and Diversity, Smithsonian Conservation Biology Institute (SCBI) scientists and partners found that using amber-colored filters to remove the blue spectra of light from "warm white" LED (light-emitting diode) lamps drastically reduces insect attraction to nocturnal lighting in a tropical forest. This is the first study to validate quantitative predictions of how lamp color affects insect attraction and provide clear recommendations t...
