Aureolaria Seed Borer
Pyrrhia aurantiago (Guenée, 1852)

Habitat [-]
The Aureolaria seed borer occurs in dry, sandy or rocky, oak-dominated savannas or open oak woods with an abundance of fern-leaf yellow false foxglove (Aureolaria pedicularia) or smooth yellow false foxglove (A. flava), the larval foodplants. These habitats are usually located on rocky uplands, along the edges of old fields, along powerline cuts, or in other openings. The larval foodplants are tall, yellow-flowered woodland herbs. The species is especially found in places that burn frequently. In New York State, it has been documented at the following places that contain the larval foodplants: 1) a powerline along a dry hill, 2) a dry slope containing mixed oak and beech woods, and 3) a rural roadside surrounded by mixed oak woods.

Associated Ecological Communities [-]
  • Coastal oak-heath forest
    A low diversity, large patch to matrix, hardwood forest that typically occurs on dry, well-drained, sandy soils of glacial outwash plains or moraines of the Atlantic Coastal Plain. The forest is usually codominated by two or more species of scarlet oak, white oak, and black oak.
  • Pitch pine-oak forest
    A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.
