The common English variety, Small Cabbage White. The fore-wings are
creamy white, with an irregular blackish mark at the tip. The male
generally has a black spot in the middle of the wing, the female having
two; and both sexes have two black spots on the underside, which is
of a yellowish colour, thickly dotted with small black atoms. All
the markings vary greatly, however. The larva is dull green, with a
yellowish stripe on its back and yellow dots on the side. It generally
feeds on the cabbage, but is found also on the nasturtium. It is very
common, and may be found everywhere from February to October. The
Ichneumon fly is a great enemy to this insect.
