Pachyprotasis rapae
Abdomen mostly black above and with dark stigma. The underside of the abdomen is extensively white. The tergites either have black apical margins, or else have narrow white margins that do not broaden on the mid-dorsal line. The species has a diagonal median black stripe in addition to the black margins and a black sterno-pleural longitudinal band. The similar Pachyprotasis similans and variegata lack the diagonal stripe.
Pachyprotasis rapae larvae feed on a broad range of plants.
