Mantled Baskettail
Epitheca semiaquea (Burmeister, 1839)

Habitat [-]
Throughout its range, Epitheca semiaquea is known from lakes, ponds, and ditches with clear water (Dunkle 2000). In New York, this species has been documented in recent years in a dwarf shrub bog in Lewis county and four different coastal plain ponds on Long Island (New York Natural Heritage Program 2009).

Associated Ecological Communities [-]
  • Coastal plain pond
    The aquatic community of the permanently flooded portion of a coastal plain pond with seasonally, and annually fluctuating water levels. These are shallow, groundwater-fed ponds that occur in kettle-holes or shallow depressions in the outwash plains south of the terminal moraines of Long Island, and New England. A series of coastal plain ponds are often hydrologically connected, either by groundwater, or sometimes by surface flow in a small coastal plain stream.
  • Dwarf shrub bog
    A wetland usually fed by rainwater or mineral-poor groundwater and dominated by short, evergreen shrubs and peat mosses. The surface of the peatland is usually hummocky, with shrubs more common on the hummocks and peat moss throughout. The water in the bog is usually nutrient-poor and acidic.
