Pieris virginiensis, the West Virginia white, is a butterfly found in North America in the Great Lakes states, along the Appalachians from New England to Alabama, and in southern Ontario.

They are typically found in moist deciduous forests.

[2] Along with the butterfly Pieris oleracea, it is threatened by the invasive weed garlic mustard, Alliaria petiolata.

[3][4] It has translucent whitish wings of length 4.5–5.5 cm; the hindwing underside has brownish or pale gray scaling along the veins.

In line 316 of Pale Fire by Vladimir Nabokov, this butterfly is referenced: “The Toothwort White haunted our woods in May.” The moniker refers to its habit of laying eggs on the toothwort.
