Olympia Marble
Euchloe olympia (W.H. Edwards, 1871)

Habitat [-]
This species is generally found in habitats with well-drained soils that appear semi-arid (Opler and Krizek 1984). In New York, the butterflies inhabit a limestone pavement barrens and alvar grassland mosaic (New York Natural Heritage Program 2017). Olympia marbles require habitats with the host plants necessary to complete their life cycle. Olympia marble larvae feed on plants in the rockcress family (Brassicaceae), particularly Arabis X divaricarpa in New York (Parshall 2002, New York Natural Heritage Program 2017).

Associated Ecological Communities [-]
  • Alvar grassland
    A community that occurs on shallow soils over level outcrops of calcareous bedrock (limestone or dolomite). Apparently alvar grasslands are restricted to areas that are seasonally flooded in spring or after heavy rainfall, as well as seasonally dry by late summer.
