      stw1/Df(2R)BSC696 adults display pigmentation defect - their bristles and wings lose the characteristic dark color and appear yellow, although the pigmentation of abdominal tergites remains largely unaffected.

      (Sickmann et al., 2017)

      RK2. Body colour: hair color yellowish, especially on legs; bristles pale at tips.
