West Virginia White
Pieris virginiensis W. H. Edwards, 1870

Habitat [-]
The West Virginia white is a forest understory species typically found in moist, rich, deciduous or mixed woods with the larval hostplant, toothwort. Many locations occupied in New York are near or along streams and the rich nature of the woods is highlighted by the presence of a host of spring ephemeral wildlflowers in addition to toothwort (New York Natural Heritage Program 2006).

Associated Ecological Communities [-]
  • Beech-maple mesic forest
    A hardwood forest with sugar maple and American beech codominant. This is a broadly defined community type with several variants. These forests occur on moist, well-drained, usually acid soils. Common associates are yellow birch, white ash, hop hornbeam, and red maple.
  • Hemlock-northern hardwood forest
    A mixed forest that typically occurs on middle to lower slopes of ravines, on cool, mid-elevation slopes, and on moist, well-drained sites at the margins of swamps. Eastern hemlock is present and is often the most abundant tree in the forest.
  • Maple-basswood rich mesic forest
    A species rich hardwood forest that typically occurs on well-drained, moist soils of circumneutral pH. Rich herbs are predominant in the ground layer and are usually correlated with calcareous bedrock, although bedrock does not have to be exposed. The dominant trees are sugar maple, basswood, and white ash.
  • Rich mesophytic forest
    A hardwood or mixed forest that resembles the mixed mesophytic forests of the Allegheny Plateau south of New York but is less diverse. It occurs on rich, fine-textured, well-drained soils that are favorable for the dominance of a wide variety of tree species. A canopy with a relatively large number of codominant trees characterizes this forest. Canopy codominants include five or more of the following species: red oak, red maple, white ash, American beech, sugar maple, black cherry, cucumber tree, and black birch.
