Species information:   There are many species of dragonflies in the Gomphid family, including about 10 genera in North America.  These are mostly stream-haunting species and are characterized by a noticeable distance between the compound eyes, giving the head a dumbbell look from above.  They also tend to have an expanded tip of the abdomen--hence the name Club-tail.  Determining species is often difficult and involves close inspection of the shape of the claspers at the end of the male's abdomen and the shape of their secondary sexual apparatus.
