This is especially true for invertebrates, which are challenging to monitor. However, new technologies leading to extremely light, animal-mounted tags are opening up new research avenues in this area. <strong><span style=\"color: #ff0000;\">Menz et al. used such tags to track the flight of death\u2019s-head hawkmoths that migrate between Europe and sub-Saharan Africa<\/span><\/strong>. <strong><span style=\"color: #ff0000;\">They found that the moths were able to correct to their specific course even in the face of disruptive winds and high mountains<\/span><\/strong>. This work suggests that the moths are not merely passively moving in the right direction, but instead actively navigating based on an internal map or compass. \u2014SNV&#8221;<\/p>\n<p style=\"text-align: justify;\">\nAbstract<br \/>\n&#8220;Each year, trillions of insects make long-range seasonal migrations. These movements are relatively well understood at a population level, but <strong><span style=\"color: #ff0000;\">how individual insects achieve them remains elusive<\/span><\/strong>. 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\u2019s-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. <strong><span style=\"color: #ff0000;\">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<\/span><\/strong>.&#8221;<\/p>\n<p style=\"text-align: justify;\">Myles H.
