Dusky Dancers can be found in a variety of freshwater habitats, ranging from small to large rivers to wind-swept lakes (Lam 2004).
In New York, Argia translata was known from eight counties (Donnelly 1999) in the southern Hudson Valley and southern tier prior to the beginning of the New York Dragonfly and Damselfly Survey (NYDDS, 2005-2009). It was documented in 10 locations within five counties in this region of the state during the NYDDS (White et al. 2010).
In New York, Argia translata was formally known from eight counties (Donnelly 1999) in the southern Hudson Valley and southern tier prior to the beginning of the New York Dragonfly and Damselfly Survey (NYDDS, 2005-2009). It was documented in 10 locations within five counties in this region of the state during the NYDDS (White et al. 2010). Despite the increased survey effort during the NYDDS, county observations decreased which could be reflective of a population decline.
Long-term information regarding population size is not available prior to the late 1990s (New York Natural Heritage Program 2017). 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 affect Dusky Dancer populations (NYS DEC 2005). Such threats may include roadway and agricultural run-off, industrial pollution, the building of dams, recreational boating, 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 2017). Both emergence rates and/or species ranges may shift for odonate species as a result of climate change (Corser et al. 2015).
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 Dusky Dancer. 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).
Dusky Dancers are known to inhabitat rivers and creeks of various sizes as well as wind-swept lakes in New York (Lam 2004, NY Natural Heritage Program 2017).
Dusky Dancer is restricted to the southern half of the state and has been documented in ten New York counties in the southern Hudson Valley and the southern tier (Donnelly 1999, White et al. 2010).
The global range for Dusky Dancer extends from northern South America northward to southern Ontario, Canada (Abbott 2006-2017). New York lies in the northeast corner of the overall range.
Dusky Dancer males have violet eyes and mostly black bodies with thin blue rings on the abdominal segments. The lower portion of his thorax is pale or powdery and immature males may have thin yellow shoulder stripes on the thorax. Females are polymorphic and light areas may be brown, greenish brown, or pale blue. They have eye spots and a long pale wedge splitting the black shoulder stripe (Lam 2004, Paulson 2011).
Dusky Dancer larvae feed on smaller aquatic invertebrates and adults feed on insects which they capture in flight.
Dusky dancer adults have been found in New York from June through the first half of September. Larvae may be found in appropriate habitats year-round.
The time of year you would expect to find Dusky Dancer present and reproducing in New York.
