Experiments provide proof of how traveling in groups protects insects

Few events involving animals are more dramatic than when they band together and head out on the march cross-country. Among examples are the many thousands of wildebeests and other hoofed mammals that form herds and migrate across the African plains. Countless millions of Mormon crickets and yo...
