Wandering Third Instar refers to a stage in the larval development of the fruit fly, Drosophila melanogaster. After hatching from its egg, the fruit fly larva spends the first days of its life eating and burrowing in rotting fruit (or fly food, if in the lab). Once sufficiently fattened and hopped up on hormones, the larva leaves the comfort of its edible home and wanders, in search of a suitable place to begin its dramatic transformation into an adult.
