Sinapis arvensis subsp.

Sinapis arvensis is an annual or winter annual plant of the genus Sinapis, belonging to the family Brassicaceae.

Sinapis arvensis is the host plant of the caterpillars of some Lepidoptera, such as the Small White (Pieris rapae).

The heavy presence of competitive exotic plants in the habitat, including charlock (Sinapis arvensis), stork's bill (Erodium cicutarium), and non-native bromes, is detrimental.

The larvae feed on Sisymbrium officinale, Descurainia sophia, Berteroa incana, Sinapis arvensis, Alliaria petiolata and Raphanus raphanistrum.

Its caterpillars can be a pest on cultivated cabbages, but it will lay eggs as well on wild members of the cabbage family such as Charlock Sinapis arvensis and Hedge Mustard Sisybrium officinale.

The larvae feed on the flowers and young fruits of Sinapis arvensis, Isatis tinctoria, Isatis glauca, Aethionema saxatile, Iberis sempervirens, Biscutella mollis, Biscutella laevigata, Bunias erucago and Aurinia saxatilis.
