Rhamphospermum arvense, (syns. Brassica arvensis and Sinapis arvensis) the charlock, sometimes also called field mustard, wild mustard, or charlock mustard, is an annual or winter annual plant in the family Brassicaceae. It is found in the fields of North Africa, Asia, Europe, and some other areas where it has been transported and naturalised. Pieris rapae, the small white butterfly, and Pieris napi, the green veined white butterfly, are significant consumers of charlock during their larval stages.
