Insects

Habitat [-]
In the northern portion of its range, this species has been found in calcareous pavement barrens. On Long Island, the precise habitat has not been verified, except that captures were made between maritime grassland and maritime dunes or between a sea level fen and maritime heathland. The following trees have been recorded as foodplants: basswood, birches, cedar, elms, maples, oaks, pines, and walnut.

Associated Ecological Communities [-]
  • Calcareous pavement barrens
    A savanna community that occurs on nearly level outcrops of calcareous bedrock (limestone or dolomite). The community consists of a mosaic of shrub-savanna, grass-savanna, and rock outcrop vegetation.
  • Maritime dunes*
    A community dominated by grasses and low shrubs that occurs on active and stabilized dunes along the Atlantic coast. The composition and structure of the vegetation is variable depending on stability of the dunes, amounts of sand deposition and erosion, and distance from the ocean.

    * probable association but not confirmed
  • Maritime grassland*
    A grassland community that occurs on rolling outwash plains of the glaciated portion of the Atlantic coastal plain, near the ocean and within the influence of offshore winds and salt spray.

    * probable association but not confirmed
  • Maritime heathland*
    A dwarf shrubland community that occurs on rolling outwash plains and moraine of the glaciated portion of the Atlantic coastal plain, near the ocean and within the influence of onshore winds and salt spray.
