Pine Barrens Bluet
Enallagma recurvatum Davis, 1913
Insects

Habitat [-]
Pine Barrens Bluets are known primarily to inhabit acidic, coastal plain ponds with sandy substrate (Nikula et al. 2003, Lam 2004) and emergent vegetation such as Bayonet Rush (Juncus militarus) along the shoreline (Massachusetts NHESP 2008) where females oviposit (Carpenter 1991). In New York, this is the case as well, and some sites also have a floating bog mat or the pond has a boggy edge (New York Natural Heritage Program 2011). In New Jersey, they are found in bogs within pine barrens (Bangma & Barlow 2010).

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.
  • Coastal plain pond shore
    The gently sloping shore of a coastal plain pond with seasonally and annually fluctuating water levels. Plants growing on the pond shore vary with water levels. In dry years when water levels are low there is often a dense growth of annual sedges, grasses, and herbs. Submerged and floating-leaved aquatic plants, such as fragrant waterlily and pondweeds, may become "stranded" on the exposed shore. In wet years when the water level is high only a few emergents and floating-leaved aquatics may be noticeable. The vegetation of this pond shore community can change dramatically from one year to the next depending on fluctuations in groundwater levels.
