Did you know?
Dragonflies of the genus Ophiogomphus are referred to as Snaketails and Ophio actually means "serpent" (Mead 2003). They get their name from the repeated color patterns on their abdomens which give them a snake-like appearance (Dunkle 2000).
|State Ranking Justification||
There are eight extant occurrences in New York State, with no population estimates determined. Future survey efforts may result in the identification of additional populations.
There is no estimate of population size for this species based on statewide occurrences. State occurrences have been reported since the early 1990's in fast-flowing streams and rivers with a rocky and sandy substrate (New York Natural Heritage Program 2007). Any new location information on the Brook Snaketail in New York may be reflective of heightened interest in surveying for this species rather than a population increase or a range expansion (Holst 2005).
There are no known historical occurrences of Brook Snaketail in New York State. Eight extant occurrences have been noted in St. Lawrence, Essex, Warren, Saratoga, Washington, Orange, and Ulster counties. Population size has not been determined for these extant occurrences, nor is long-term information regarding populations available prior to 1990 (New York Natural Heritage Program 2007).
