Some authors divide the genus Gomphus into Subgenera, which keeps similar species in their own group.
In Gomphus (Phanogomphus) there are 4 species in our area.
I have made plates to try to make it easier to separate these 4 species.

Tony, this is Awesome!!  I just learned the difference between the Lancer and the Beaverpond...it's great to have all four together like this.  I'll have to save it in my Ode File!! 

Wow! This is great, Tony.

This should be on a giant poster and framed on my wall ... excellent Tony!
