Genus Pieris
All Leps lists five species, including the introduced species P. rapae.
Feed on members of the Brassicaceae family. They have developed biochemical adaptations to chemicals called glucosinolates present in these plants.
Life Cycle
The highest species variety is in the Palaearctic. A few crop-damaging species have been introduced from this area, such as the cabbage white (Pieris rapae), which has become the most abundant representative of this genus and perhaps of all butterflies. The parasitoid Cotesia glomerata has been introduced to control this pest.
