Needham's Skimmer is known to occur in nine locations in Richmond, Rockland, Putnam (two locations), and Suffolk counties since 1997 (New York Natural Heritage Program 2007). The species is also known to occur in Kings, Orange, and Westchester counties (Donnelly 1999). Population estimates have not been determined. Further survey efforts may result in the identification of additional populations or range expansions and may enable population sizes to be determined.
No estimate of population size has been made for Needham's Skimmer based on observations from 1997 to present (New York Natural Heritage Program 2007). Information prior to this time frame is limited. Therefore, any new location information on Needham's Skimmer in New York may reflect heightened interest in surveying for this species rather than a population increase or a range expansion (Holst 2005).
Nine recent observations of Needham's Skimmers have been made in Putnam, Richmond, Rockland, and Suffolk counties since 1997 (New York Natural Heritage Program 2007). The species is also known to occur in Kings, Orange, and Westchester counties (Donnelly 1999). Since there is limited historical information, few recent records, and the full extent and size of the populations have not been determined, long-term trends are unclear.
