Springer Nature's academic journal "Nature Communications" published an animal behavior research paper in the early morning of January 31st, Beijing time. They found that insects have a "dorsal light response" by correcting their flight path so that their backs face the light source.
For natural light sources such as the sun, this response allows them to maintain a stable flight path accurately positioned on the horizon. However, artificial light can cause them to make erratic and constant corrections to their flight paths, causing insects to become dazzled.
