Switchgrass Dart
Dichagyris acclivis (Morrison, 1875)
Insects

Habitat [-]
The habitat for this species in New York State seems to be sandy, grassy areas with an abundance of switchgrass (Panicum virgatum). Larvae commonly feed on this grass in wet places such as ditches and streamsides (D. Schweitzer, personal communication).

Associated Ecological Communities [-]
  • 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.
  • 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.
  • Sea level fen*
    A wetland that occurs at the upper edge of salt marshes but is fed primarily by acidic groundwater seeping out along the upland edge. This fresh water sometimes mixes with salt or brackish water during unusually high tides. There is a high abundance of sedges that decompose slowly and create a deep substrate of peat. This peat is underlain by deep sand or gravel. These fens usually have a high diversity of herbs but may also have scattered trees and shrubs.
