Abstract: There are 195 species of odonates (dragonflies and damselflies) known to live (or once live) in New York State, and Long Island is home to roughly 100 of them, with some of the highest diversity in the state. Among them are several rare species including the three state threatened damselflies: Little Bluet (Enallagma minusculum), Scarlet Bluet (Enallagma pictum) and Pine Barrens Bluet (Enallagma recurvatum). The New York Dragonfly and Damselfly Survey (NYDDS) began in 2005, spanned five field seasons through 2009, and relied heavily on citizen scientists to help collect data over a large geographic area. Its primary goal was to document the current distribution of all odonate species in New York State, but one outcome was an assessment of species’ conservation status. We will explore odonate natural history and findings from the New York Dragonfly and Damselfly Survey (NYDDS; 2005-2010) to highlight Long Island’s odonate biodiversity and rarity. In addition, we’ll explore odonates ranked higher in vulnerability for the Northeast region that have populations on Long Island using the Conservation Status Assessment of Odonata for the Northeastern United States (2012-2014) as a reference.
