State Rarity Rank: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

Did you know?
Unlike most actively flying darners, this species is known to pluck prey items from herbaceous vegetation (Paulson 2011), a feeding technique termed "gleaning."

State Ranking Justification [-]
This darner is almost always found in low densities at widely scattered locations, which seem to vary from year to year. Its distribution in New York seems to have shrunk considerably, from eight occupied counties historically, to just four during the mid 2000s (White et al 2010), none of which was historically known.
