Flies are small and inviable. Wings are shorter than normal and form a canopy over the abdomen, with the tips converging towards the mid-dorsal line. The head and eyes are slightly deformed. The abdominal tergites are abnormal to varying degrees, ranging from irregular pigmentation to absence or gross deformation of the 6th and 7th tergites.
