Insects are the world's smallest flying migrants, but they can maintain perfectly straight flight paths even in unfavorable wind conditions, according to a new study from the Max Planck Institute of Animal Behavior (MPI-AB) and the University of Konstanz. Researchers radio tracked migrating hawkmoths for up to 80 kilometers—the longest distance that any insect has been continuously monitored in the wild. By closely following individuals during migration, the world-first study unlocks a century-old mystery of what insects do over their long-range journeys.
