对北美东部帝王蝶（Danaus plexippus）迁徙的研究揭示了其导航背后的机制。在向南和向北迁移期间，主要的定向机制使用了一个时间补偿的太阳罗盘。日光信号，如太阳本身和偏振光，通过两只眼睛处理，并通过大脑中央复合体的复杂电路整合，该复合体被认为是太阳指南针的位置。帝王蝶的生物钟有独特的分子机制，那些驻留在触角上的生物钟提供了时间补偿。最近的证据表明，在没有定向日光提示的情况下，迁徙者也可以使用依赖于光的倾斜磁罗盘来确定方向。黑脉金斑蝶的基因组已经被测序，利用基于核酸酶的技术来编辑特定基因的遗传策略已经被开发出来。帝王蝶已经成为研究远距离动物迁徙的神经、分子和遗传基础的一个模型系统。
Studies of the migration of the eastern North American monarch butterfly (Danaus plexippus) have revealed mechanisms behind its navigation. The main orientation mechanism uses a time-compensated sun compass during both the migration south and the remigration north. Daylight cues, such as the sun itself and polarized light, are processed through both eyes and integrated through intricate circuitry in the brain's central complex, the presumed site of the sun compass. Monarch circadian clocks have a distinct molecular mechanism, and those that reside in the antennae provide time compensation. Recent evidence shows that migrants can also use a light-dependent inclination magnetic compass for orientation in the absence of directional daylight cues. The monarch genome has been sequenced, and genetic strategies using nuclease-based technologies have been developed to edit specific genes. The monarch butterfly has emerged as a model system to study the neural, molecular, and genetic basis of long-distance animal migration.
