为什么某些蛾类利用月光导航，却会被路灯迷惑？

Many night-flying moths use celestial navigation, keeping the moon at a constant angle to fly straight.
Since the moon is extremely far away, its light rays reach Earth almost parallel, making this method reliable.
Streetlamps, however, emit light in all directions, so their rays converge sharply on nearby objects.
A moth trying to hold a fixed angle to the lamp spirals inward until it hits the bulb or flame.
This error does not happen with stars because they are even farther—and dimmer—than the moon.
Some moths also detect polarized light patterns in twilight skies to calibrate their internal compass.
Artificial light disrupts mating signals, feeding rhythms, and larval development in many insect species.
LED lights worsen the problem because their blue-rich spectrum mimics daylight more closely.
Conservationists now install shielded, amber-colored lights near habitats to reduce disorientation.
This shows how ancient biological strategies can clash with modern human technology in unexpected ways.

Conservationists now install shielded, amber-colored lights near habitats to reduce disorientation. 保护工作者如今在栖息地附近安装遮蔽式琥珀色灯具，以减少昆虫迷失方向。
LED lights worsen the problem because their blue-rich spectrum mimics daylight more closely. LED灯加剧了这一问题，因其富含蓝光的光谱更接近白昼光线。
Artificial light disrupts mating signals, feeding rhythms, and larval development in many insect species. 人工光源会干扰多种昆虫的交配信号、摄食节律和幼虫发育。
