Small White - Pieris rapae

Small and Large Whites are the two species that are most often confused. Both are extremely common and both are serious pests. In both species there is a marked difference between the sexes. Small Whites are slightly smaller than Large Whites. The easiest distinguishing feature is the extent of the black patch on the wing. In Small White the patch only extends a short distance down the wing margin. The males have a single spot on the fore wing while the female (illustrated) has two merging spots below the center of the fore wing in addition to the single spot.
