    I cannot provide an "adaptive" mutation in fruit flies. However
    I believe that there are at least two strains of "dwarf" mice
    which show extended longevity. Now why "dwarf" mice should
    have this characteristic is open to a lot of debate.

    But the Jackson Laboratory is happy to provide them to you to
    find out... For example:

    http://jaxmice.jax.org/jaxmice-cgi/jaxmicedb.cgi?objtype=pricedetail&stock=000643

    Documents the "Snell's dwarf" mouse.

    Now as to whether the mutation is "adaptive" -- the world only
    has to undergo a brief exposure to the radiation from a supernova
    which may cause a decrease in food resources and the "dwarves"
    will likely be the winners in the selection game.

    In normal conditions presumably "dwarf" mice have a survival advantage
    in any environment where food resources are diminished.
