Insects

Habitat [-]
In New York State, this species is found exclusively in the open-canopy dwarf pine barrens and pitch pine-oak heath woodlands of Long Island. Pitch pine and scrub oak are the dominant plant species in both of these habitats. It is suspected that the larval food source is scrub oak.

Associated Ecological Communities [-]
  • Dwarf pine plains
    A woodland community dominated by dwarf individuals of pitch pine and scrub oak that occurs on nearly level outwash sand and gravel plains in eastern Long Island. The soils are infertile, coarse textured sands that are excessively well-drained.
  • Pitch pine-oak-heath woodland
    A pine barrens community that occurs on well-drained, infertile, sandy soils. The structure of this community is intermediate between a shrub-savanna and a woodland. Pitch pine and white oak are the most abundant trees.
