Researches at the Howard Hughes Medical Institute and the Center for Developmental Genetics were surprised to discover that nearly every segment of a fruit fly larva contains light-sensitive cells. The fly probably evolved this feature as a response to the need to avoid sunlight. The larvae must burrow deep into their chosen fruit, where they live off yeast. Too close to the fruit’s surface and not only do they run out of yeasty goodness, but they also get shriveled up by the sun and the elements.
