From Wikipedia:
The D. melanogaster lifespan is about 30 days at 84 °F.
The developmental period for Drosophila melanogaster varies with temperature, as with many ectothermic species.
The shortest development time (egg to adult), 7 days, is achieved at 82 °F.Development times increase at higher temperatures (11 days at 86 °F) due to heat stress.
Under ideal conditions, the development time at 77 °F is 8.5 days.
At 64 °F it takes 19 days.
At 54 °F it takes over 50 days.
Under crowded conditions, development time increases, while the emerging flies are smaller.Females lay some 400 eggs (embryos), about five at a time, into rotting fruit or other suitable material such as decaying mushrooms and sap fluxes. The eggs, which are about 0.5 millimetres long, hatch after 12–15 hours (at 77 °F).The resulting larvae grow for about 4 days,while molting twice (into 2nd- and 3rd-instar larvae), at about 24 and 48 hours after hatching.During this time, they feed on the microorganisms that decompose the fruit, as well as on the sugar of the fruit itself. Then the larvae encapsulate in the puparium and undergo a four-day-long metamorphosis, after which the adults eclose (emerge).
