Rambur's Forktail
Ischnura ramburii (Selys, 1850)
Insects

Habitat [-]
In the northeast, Rambur's Forktail is found at coastal plain ponds, lakes, marshes, and slow-flowing rivers or streams, often with brackish water (Nikula et al. 2003, Lam 2004).

Associated Ecological Communities [-]
  • Brackish tidal marsh*
    A marsh community that occurs where water salinity ranges from 0.5 to 18.0 ppt, and water is less than 2 m (6 ft) deep at high tide. The vegetation in a brackish tidal marsh is dense and dominated by tall grass-like plants.

    * probable association but not confirmed
  • 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.
  • Coastal salt pond
    A community inhabiting marine shoreline lakes or ponds formed by sandspits that close off a lagoon or bay. The water typically averages brackish or slightly brackish over long periods of time, but may range rapidly from fresh to saline.

Associated Species [-]
  • Seaside Dragonlet (Erythrodiplax berenice)
  • Citrine Forktail (Ischnura hastata)
  • Fragile Forktail (Ischnura posita)
  • Needham's Skimmer (Libellula needhami)
