Remarks
"The family Pieridae contains many species, most of which are white or yellow, marked with black and orange. They are usually called 'whites' or 'sulphurs'. In fact, the common name, 'butterfly', indicates this yellow or yellow-orange color of the insects. This common name was probably first applied to yellow European members of this family. They are very abundant and are often found at mud puddles. There are many common forms, such as the cabbage butterfly, (Pieris rapae), an introduced species and one of our most abundant and widespread species, generally recognized by everyone."(1)
