Insects |  Printer Friendly Version (PDF) |
Family: Clubtails (Gomphidae)
State Protection: Not Listed 
The species is not listed or protected by New York State. Federal Protection: Not Listed State Rarity Rank: S3
A State Rarity Rank of S3 means: Typically 21 to 100 occurrences, limited acreage, or miles of stream 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? All adult dragonflies are aerial predators that hunt and capture other insects on the wing for food. Gomphus females have larger spines on their hind legs, allowing them to capture larger prey than their male counterparts (Dunkle 2000). |

| State Ranking Justification | [-] |
There are five extant and two historical locations where this species is known to occur in New York State, with no population estimates determined. There are two locations in the state where exuviae have been found, but no adult sightings were confirmed. If these records are confirmed, this may change the rank to an "S2".
| Short-term Trends | [-] |
There has been no estimate of population size for this species based on statewide occurrences. These occurrences have been reported from the late 1990's to present, and information prior to this time frame is limited. Therefore, any new location information on the Rapids Clubtail 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).
| Long-term Trends | [-] |
There are two known historical occurrences of Gomphus quadricolor in New York State, in Broome and Tompkins counties. Five extant occurrences have been located in Warren, Saratoga, Orange, Ulster, St. Lawrence, Sullivan, and Broome counties. There is no existing information regarding the current existence of populations at these locations; therefore long-term trends are unclear.
