通过使用轻型飞机和个体无线电跟踪，研究人员表明夜间迁徙的鬼脸天蛾在长距离内保持对其飞行轨迹的控制。飞蛾不只是在有利的尾风下飞行；在一个特定的夜晚，它们还调整顺风和横风以精确地保持航向。这种行为表明，飞蛾使用一个复杂的内部罗盘来保持独立于风况的季节性有益的迁徙轨迹，这阐明了昆虫如何穿越长距离来利用季节性资源。
据介绍，每年，数万亿的昆虫进行长距离的季节性迁移。这些迁移在种群水平上相对来说比较好理解，但是单个昆虫如何实现这些迁移仍然难以捉摸。对途中条件的行为反应的研究很少，主要是由于追踪单个昆虫的难度。

Abstract: Each year, trillions of insects make long-range seasonal migrations. These movements are relatively well understood at a population level, but how individual insects achieve them remains elusive. Behavioral responses to conditions en route are little studied, primarily owing to the challenges of tracking individual insects. Using a light aircraft and individual radio tracking, we show that nocturnally migrating death’s-head hawkmoths maintain control of their flight trajectories over long distances. The moths did not just fly with favorable tailwinds; during a given night, they also adjusted for head and crosswinds to precisely hold course. This behavior indicates that the moths use a sophisticated internal compass to maintain seasonally beneficial migratory trajectories independent of wind conditions, illuminating how insects traverse long distances to take advantage of seasonal resources.
