布冈夜蛾何以飞越千里？国际最新研究发现或能利用星辰导航

Core Insights - The research published in the journal "Nature" identifies the Bogong moth (Agrotis infusa) as potentially the first known invertebrate capable of using star navigation [1][3]. Group 1: Research Findings - The study reveals that Bogong moths utilize celestial cues and magnetic sensing to navigate correctly during their migration [3][5]. - Each spring, billions of nocturnal Bogong moths migrate nearly 1,000 kilometers from southeastern Australia to cooler caves in the Australian mountains, a location they have never visited before [3][5]. - The research indicates that the moths' brain neurons respond specifically to the rotation of the night sky, adjusting to the celestial direction, with peak activity occurring when the moths face south [5][7]. Group 2: Methodology - Researchers captured Bogong moths during their migration seasons and placed them in a flight simulator that mimicked the night sky while blocking the Earth's magnetic field [5]. - The flight direction of the captured moths aligned with their seasonal migration paths, suggesting a strong reliance on celestial navigation [5][7]. Group 3: Implications - The study raises questions about the specific visual features that aid moth navigation, although it is suggested that the Milky Way may be visible to the moths [7].
