Scientists at Caltech , using fermented juice as bait have discovered that a fruit fly can travel six million times its body length in search of food. 

Flies were lured by “a tantalizing cocktail of fermenting apple juice and champagne yeast  produces carbon dioxide and ethanol, which are irresistible to a fruit fly.” Scientists released buckets of fruit flies on a dry lakebed in California’s Mojave Desert, far away from any other tempting food source.
