The close relatives of the St. Croix Snaketail include the Riffle, Brook, and Sand Snaketail species.  These dragonflies may look very similar to the St. Croix Snaketail but they all exhibit different behaviors in their respective environments (Dunkle, 2000).  The St. Croix Snaketail also has the shortest season among the previously listed species, ranging from late May to late June.

We became interested in this organism because it is rare and poorly understood.  Interestingly, the St. Croix Snaketail was put on the endangered species list just three years after its discovery in 1993 by Vogt and Smith.  Others should find this organism to be interesting because they may not be able to see one in the wild for much longer.  Like many great predators, the St. Croix Snaketail has no major threats to worry about other than humans (IUCN Red List, 2009).  Since this species is particularly sensitive to pollution it is likely that humans will eventually contaminate their environment, causing them to become extinct.  We hope that future research on the St. Croix Snaketail will give us more information about this illusive dragonfly.
