The Cabbage Butterfly, a common little insect, is one of a small family known scientifically as the Pieridae.
There are three groups: the Whites, the Sulphurs, and the Orange-tips.
The names give you a pretty good idea of their colours. All of them are quite small, about two inches or so across the wings.
The main wings often have black marks at the tips, black dots or splotches, and some have black edges.
The Cabbage Butterfly is the most common one of all. It is white with black tips on its forewings, and one black spot on each forewing, too.
