Fruit Fly Pupae
Fruit flies begin as eggs, from which they hatch into larvae. Fruit fly larvae then pupate in order to develop into adults. Fruit flies typically spend eight days between the egg and larval stages and remain inside the pupal stage for approximately six more days. Most fruit flies are producing mature adults within two weeks.
Twenty-four hours before the adult fruit fly emerges from the puparium, the red eyes and folded wings are visible through the surface. The puparia turn black when adults are ready to emerge. After forcing their way through the puparia, adults are light in color and have elongated wings and abdomens. Within a few hours, these new adults will darken.
