某些蛾类如何仅靠星光导航？

Nocturnal moths like the Bogong moth detect polarized patterns in starlight using specialized photoreceptors.
Their compound eyes contain dorsal rim areas tuned to ultraviolet wavelengths scattered by night sky stars.
Even under moonless conditions, they maintain straight flight paths by referencing the Milky Way’s band.
Laboratory experiments prove they lose orientation when star patterns are obscured or rotated artificially.
This celestial navigation supports multi-night migrations spanning hundreds of kilometers to cool mountain refuges.
Unlike birds, moths lack internal magnetic compasses and rely entirely on visual sky cues.
Urban light pollution disrupts their ability to resolve faint stellar gradients, causing disorientation.
Researchers attach micro-tracking devices to study real-time flight behavior across diverse landscapes.
Evolutionary biologists compare moth neural circuits with those of dung beetles that also navigate by stars.
Understanding this system aids conservation planning for habitats aligned with natural light-pollution thresholds.

Researchers attach micro-tracking devices to study real-time flight behavior across diverse landscapes. 研究人员为蛾类安装微型追踪装置，以实时研究其在多样地貌中的飞行行为。
Urban light pollution disrupts their ability to resolve faint stellar gradients, causing disorientation. 城市光污染干扰其分辨微弱恒星梯度的能力，导致迷失方向。
Understanding this system aids conservation planning for habitats aligned with natural light-pollution thresholds. 理解这一系统有助于依据自然光污染阈值制定栖息地保护规划。

这篇中文题目最接近哪一句？某些蛾类如何仅靠星光导航？一次学校运动会的通知一份超市购物清单

课文第一句的意思更接近？夜行性蛾类（如博贡蛾）利用特化的光感受器探测星光中的偏振模式。今天学校放假了。请把窗户打开。
