From Brassica rapa various interrelated vegetable varieties have been developed, including turnips, bok choi, pak choi and napa cabbage. Wild Turnip is host for the larvae of a number of moths and butterflies: Silver Y (Autographa gamma) Evergestis pallidata, Cabbage Moth (Mamestra brassicae), Large Yellow Underwing (Noctua pronuba), Large White (Pieris brassicae), Green-veined White (Pieris napi) and Small White (Pieris rapae).
