Southern Sprites measure about an inch long and are one of the tiniest odonates in New York (Lam 2004).
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.
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).
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.
Any activity which might lead to water contamination or the alteration of natural hydrology could impact Southern Sprite populations (NYS DEC 2005). Such threats might include roadway and agricultural run-off, ditching and filling, eutrophication, changes in dissolved oxygen content, and development near their habitats (NYS DEC 2005). Groundwater withdrawal is a potential threat in lentic habitats, as are invasive plant species replacing native plants required for oviposition (New York Natural Heritage Program 2010). Both emergence rates and/or species ranges may shift for odonate species as a result of climate change (Kalkman et al. 2008).
Any efforts to reduce roadway and agricultural run-off, eutrophication, development of upland borders and resulting increased groundwater withdrawal, and ditching and filling activities should be considered when managing for this species (NYS DEC 2005).
Further research is needed to define the distribution and population size of the Southern Sprite. In addition, research is required to understand the habitat requirements and threats to this species, and to create appropriate management guidelines for its persistence in known locations (NYS DEC 2005).
In the northeast, Southern Sprites are found on the coastal plain at grassy ponds, lakes, marshes, and bogs (Lam 2004, Bangma & Barlow 2010). In New York, known habitats are coastal plain ponds on Long Island (New York Natural Heritage Program 2010).
In New York, at the northern tip of its range, 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). The species appears to be restricted to Long Island with a single documentation in Suffolk county during the increased statewide survey effort for odonates during the New York Dragonfly and Damselfly Survey.
The species' known range includes Texas and Oklahoma eastward across the southern United States, then northward along the Atlantic coast to New Hampshire (Donnelly 2004b, Abbott 2010).
Male Southern Sprites are metallic green on top of their thorax and a dark, iridescent green on the top of their abdomen. The exceptions are abdominal segments 9 and 10, which are mostly blue, with a dark, "fang-like" pattern on segment 9. They are 0.8-1 inch long and are the smallest sprites in the northeast, on average (Lam 2004). Females are also metallic green on top, with yellow or blue thoracic sides, and pale blue on the top of abdominal segment 10. The rear edge of the prothorax is smoothly rounded and lacks any lobes.
New York records indicate that the species may be observed on Long Island between June 27 and July 27 (Donnelly 1999, New York Natural Heritage Program 2010). In New Jersey, they have been documented from June 8 through August 11 (Bangma & Barlow 2010).
The time of year you would expect to find Southern Sprite present and reproducing in New York.
