CBCGDF expert SHEN Yihang: In Changde City, Hunan Province, on September 4, Hundreds of Millions of Mayflies Gathered Again in the Yuan River. Is It Caused by Light Pollution?

On the evening of September 1, 2024, a large number of mayflies (Ephemeroptera) gathered on the Yuanshui Bridge in Hanshou County, Hunan Province, "attached to the bridge like snow, and piled several centimeters thick on the road. Three days later, on September 4, a large number of mayflies appeared again in Hanshou County, Changde, Hunan, flying all over the sky, like snowflakes falling, and the ground was covered with a thick layer of flying insects. Due to the large number of mayflies, the road of Hanshou Yuanshui Bridge was forced to be closed until after 10 o'clock that night.

The author believes that this incident may also be related to modern light pollution. Because the adult mayflies will be affected by the light source after they emerge Attraction, especially artificial light sources at night (such as street lights, bridge lighting, etc.), causes a large number of mayflies to gather and fly. This is why mayflies often appear in places with lights, giving people the impression of "flying all over the sky".

The so-called light pollution refers to the pollution caused by artificial light sources to the night environment, which may often interfere with the natural light and dark cycle, affect the normal behavior of animals and plants and the balance of the ecosystem. Insects have natural rhythms, and they have biological rhythmic responses to changes in light and dark, but light pollution may break this natural rhythm, making it impossible for insects to act according to their normal biological clock.
