Each spring, billions of Bogong moths migrate from southeast Australia to hibernate in the Snowy Mountains' alpine caves, returning in autumn to breed. Lab tests confirmed they fly seasonally south in ...

为解决夜间迁徙昆虫如何导航这一科学难题，研究人员通过飞行模拟器和电生理技术，首次揭示Bogong蛾利用银河系特征构建"星象罗盘"的神经机制。该研究发现蛾类脑内存在特化神经元群，能解码夜空方位并与地磁信号协同导航，为理解无脊椎动物长距离迁徙提供了新范式，发表于《Nature》。 每当南半球春季来临，数以亿计的Bogong蛾(Agrotis infusa)便会展开一场史诗般的迁徙之旅。这些夜行性昆虫从 ...
