Insects |  Printer Friendly Version (PDF) |
Family: Pond Damsels (Coenagrionidae)
State Protection: Species Of Special Concern 
A native species at risk of becoming Threatened; does not qualify as Endangered or Threatened, but have been determined to require some measure of protection or attention to ensure that the species does not become threatened. NYSDEC may regulate the takin Federal Protection: Not Listed State Rarity Rank: S1
A State Rarity Rank of S1 means: Typically 5 or fewer occurrences, very few remaining individuals, acres, or miles of stream, or some factor of its biology makes it especially vulnerable in New York State. Global Rarity Rank: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery. Did you know? Southern Sprites measure about an inch long and are one of the tiniest odonates in New York (Lam 2004). |

| State Ranking Justification | [-] |
In New York, there are at least five older records for N. integricollis in Suffolk county (Donnelly 1999), and two extant locations in Suffolk county (1995 and 2005) (New York Natural Heritage Program 2010). Despite increased survey efforts on Long Island in recent years for the New York Dragonfly and Damselfly Survey (2005-2009), one new location has been documented during those years.
| Short-term Trends | [-] |
No estimation of population size for this species has been made based on observations from 1995 and 2005 in Suffolk county (New York Natural Heritage 2010). There are observations made prior to this at five other locations in Suffolk county (Donnelly 1999), but information prior to the late 1990s is limited (Donnelly 2004). Therefore, any new location information on Southern Sprite in New York may reflect heightened interest in surveying for this species rather than a population increase or a range expansion (NYS DEC 2005).
| Long-term Trends | [-] |
Recent observations have been noted in Suffolk county in 1995 and 2005. Long-term information regarding population size is not available prior to the late 1990s (New York Natural Heritage Program 2010). Since observations are fairly recent, and the full extent and size of the populations have not been determined, long-term trends are unclear.
