Family: Emeralds (Corduliidae)

State Protection: Not Listed
The species is not listed or protected by New York State.

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: G3G4
A Global Rarity Rank of G3G4 means: Vulnerable globally, or Apparently Secure -- At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors. More information is needed to assign a single conservation status.

Did you know?
Even though this dragonfly is almost never seen in broad daylight, sometimes a mass emergence occurs in late May or early June, when hundreds of these otherwise cryptic river denizens float on the breeze above the river.

State Ranking Justification [-]
This newly described species (Brunelle 2000) was discovered as a new member of the New York odonate fauna in 2008 during the New York Dragonfly and Damselfly Survey (White et al. 2010). It is only known from a short (~ 20 Km) stretch on the upper Delaware River and this population is disjunct from the main range forming a small outlier on the extreme southern range boundary of this northerly species. No new locales have been documented since 2009 and this cryptic, crepuscular species will always likely suffer from a lack of complete knowledge.
