This species is common in the Great Yeldham area, though less common than Green-veined White.
The Small White has two broods per year. The larval food plants are various members of the cabbage family, such as Garlic Mustard which is common in hedgerows in the parish. They over-winter as pupae, hatching in spring. The adults are on the wing from midspring to early autumn with a slight gap between broods in late June.
They differ from the Green-veined Whites on the topsides of the wings by the lack of small triangles at the outer ends of veins and on the undersides of the hind wings by the lack of green to grey veins.
