Family: Clubtails (Gomphidae)

State Protection: Species Of Special Concern
A native species at risk of becoming Threatened; does not qualify as Endangered or Threatened, but have been determined to require some measure of protection or attention to ensure that the species does not become threatened. NYSDEC may regulate the taking, importation, transportation, or possession of any Species of Special Concern as it deems necessary.

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: G5
A Global Rarity Rank of G5 means: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Possibly because of their short stocky legs, Sanddragons don't perch in riparian trees and shrubs to the extent that most clubtails do, but rather on the ground (Jones et al. 2008).

State Ranking Justification [-]
This is one of the rarest dragonflies in the state. Currently, there are only four known extant populations; two nearby ponds on the northshore of Long Island, and along the upper Hudson and Schroon Rivers in the southern Adirondacks. Despite an intensive statewide odonate survey between 2005-2009 (White et al. 2010), no new significant finds were made beyond the known historical distribution. Abundance levels at the Suffolk County ponds are fairly robust, while only small numbers of larvae have been found on the upper Hudson, and the Schroon River population was not re-confirmed during NYDDS.
