Fruit Fly Life Cycle
EGG - The fruit fly life cycle begins as an egg. Female fruit flies commonly lay their eggs inside rotting fruit because the fermenting process creates additional sugars that are good for the offspring. Another requirement for the environment of the eggs is that it must be between 20-40 degrees Celcius in order for them to thrive. Fruit fly females are capable of laying up to 400 eggs at a time. The eggs hatch into larvae within 24 hours.
LARVAE - Larvae are the small worm like early stages of fruit flies. After fruit fly eggs hatch, larvae begin to feed on the decaying materials within which they were laid. Larvae consume as much food as possible in order to store energy and nutrients for the upcoming pupal stage. After feeding, larvae find cooler, dryer locations within which to pupate.
METAMORPHOSIS - At room temperature, fruit flies can develop into adults within one to two weeks. The egg and larval stages span approximately eight days, while the pupal stage lasts six days. The adult fruit fly lives for several weeks. Twenty-four hours after a female fruit fly lays her eggs, larvae hatch. The pupa case if formed from the larval skin as it darkens and develops a hard surface. Fruit fly adult develops in this pupal stage. Twenty-four hours before the adult emerges, the pigmentation of the eyes and the folded wings are already visible through the pupal case, called the puparium. The pupa darkens just before the adult fly emerges. When metamorphosis is complete, the adult fruit fly pushes its way through the anterior end of the puparium. Initially, the fruit fly is light in coloration, with expanded wings and an elongated abdomen. Within a few hours, the fruit fly darkens, extends its wings and expands its abdomen. Approximately 48 hours after emerging from the puparia, female fruit flies are sexually mature and can begin breeding and laying eggs. Adult fruit flies are fertile for the entirety of their life spans. Female fruit flies can store sperm from multiple inseminations for use in future egg productions.
PUPAE - 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.
