Depends on the species - i suspect you mean D melanogaster (wild type).
Inseminated females will survive for months with a daily mortality probability
of around 5% or so. (We've had ffemales live >>> 6 months).
Similar long lives have been recorded for other species with larger bodied
species generally living longer that smaller bodied species.
All of this is beside the point however since in the wild the mortality
probability is around 70% a *day* and few individuals live more than 3 days.
This means that genes expressed in flies older than a week or so are in effect
Does anybody really know ? I doubt it but 85-90% is likely to be in the right
