Insects

Habitat [-]
Needham's Skimmer is a coastal species that inhabits ponds, lakes, tidal river areas, and brackish wetlands in New York State (Dunkle 2000, New York Natural Heritage Program 2007, Nikula et al. 2003). Larvae are aquatic and found in the water during this lifestage, whereas adults are terrestrial and are found in habitats surrounding ponds, lakes, and brackish wetlands.

Associated Ecological Communities [-]
  • Brackish intertidal mudflats
    A sparsely vegetated community, characterized by low-growing, rosette-leaved aquatics. The community occurs on exposed intertidal mudflats where water salinity ranges from 0.5 to 18.0 ppt. This community is best developed where mudflats are nearly level so that broad expanses are exposed at low tide. The rosette-leaved aquatics are completely submerged at high tide, and they are usually coated with mud.
  • 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.
  • 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.

  • Tidal river
    The aquatic community of a river under the influence of daily lunar tides. We restrict this community to the continuously flooded portions of the river where plants do not grow out of the water. A deepwater zone has depths averaging more than 2 m (6 ft) at low tide. Salinities at any one place in the river may fluctuate as the tides flow in and out.
