Jeffrey Pippen
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: S2
A State Rarity Rank of S2 means: Typically 6 to 20 occurrences, few remaining individuals, acres, or miles of stream, or factors demonstrably make it very 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?
Female Baskettails use their flat and forked subgenital plates on the underside of their abdomens to carry their eggs in a "basket". They deposit the whole mass of several hundred eggs from the basket with a double dip into the water (Dunkle 2000).

State Ranking Justification [-]
A single specimen was collected from a large wetland in Lewis County in 2006. It is unknown if this represents a breeding population or a stray individual, since this is primarily a coastal species. A single specimen was collected from four different coastal plain ponds in Suffolk County in 2008 (New York Natural Heritage Program 2009). It is unclear how many breeding populations may be present on Long Island. Additional survey efforts at historical, potential, and extant locations are warranted to better understand the status of this species in New York State.
