许多昆虫进行长距离的季节性迁徙，以利用数百或数千公里外的临时繁殖地，但促进这些运动的行为适应在很大程度上仍然未知。使用昆虫雷达，我们发现，选择季节性有利的，高海拔的风是广泛的大型白天和夜间飞行的移民和昆虫采用最佳的飞行航向，部分纠正风漂移，从而最大限度地提高旅行的距离。轨迹分析表明，这些行为增加了40%的迁移距离，并减少了从季节性最佳方向漂移的程度。这些飞行行为与候鸟的复杂飞行行为相匹配，有助于解释高空飞行的昆虫如何在季节性栖息地之间成功迁移。
Many insects undertake long-range seasonal migrations to exploit temporary breeding sites hundreds or thousands of kilometers apart, but the behavioral adaptations that facilitate these movements remain largely unknown. Using entomological radar, we showed that the ability to select seasonally favorable, high-altitude winds is widespread in large day-and night-flying migrants and that insects adopt optimal flight headings that partially correct for crosswind drift, thus maximizing distances traveled. Trajectory analyses show that these behaviors increase migration distances by 40% and decrease the degree of drift from seasonally optimal directions. These flight behaviors match the sophistication of those seen in migrant birds and help explain how high-flying insects migrate successfully between seasonal habitats.
