Researchers use radar to track 3.5 trillion migrating insects over England

Researchers in the UK have turned some highly specialized radar equipment to the skies to track a staggering volume of material—3.2 kilotons of it—as it transits the skies of southern England. The material in question? Insects, about 3.5 trillion of them each year. While smaller insects seem to drift on the prevailing wind, larger ones appear to undergo a directed, seasonal migration.
