      Deposition of electron-dense material in nucleus and cytoplasm of fat cells begins during pupal stage; pericardial cells of adult become filled with electron-opaque granules and vacuoles.

      (Perotti and Bairati, 1968)

      Pupa and young fly characterized by accumulation of dark pigment; in older fly, pigment becomes concentrated in black specks scattered through body, head, and legs. RK2.
