It was a dark and windy night, but millions of moths migrating over Britain could still tell which way they were going.
Radar showed that silver Y moths heading south for winter selected winds sweeping them in the right general direction, says Jason Chapman of Rothamsted Research in Harpenden, England. Moths even seemed to adjust their flight direction to compensate for somewhat off-course winds, he and his colleagues report in the April 8 Current Biology.
