D. melanogaster larvae feed on FAOs. (a) Larvae associate in clusters and feed underneath beef (the beef was turned upside down to take the picture in a and c). (b) The yellow yolk (left) and the orange food dye (right) can be seen in the guts of the larvae. (c) The “canals and ditches” dug underneath beef by foraging larvae. (d–f) The adults fed and laid eggs on moldy beef on the 4^th day, and on the 5^th day, the mold was removed by a cohort of larvae. The meat was moistened, liquefied and eaten by the larvae on the 6^th day.
