Cabbage Butterflies

Cabbage Butterflies, the name given to several species of white butterflies, of which five occur in England; they belong to the genus Pieris. As they are usually born in successive broods, they occur all the year round, and are the most familiar of British butterflies. P. rapae is the best known, and sometimes occurs in great swarms. It has now become established in Canada.
