I propose the most recent (Feb 2005) Taxonomy
http://www2.ups.edu/biology/museum/NAdragons.html as the list to adopt. I've actually made an "executive decision" and changed the
Aeshna Taxonomy page
http://bugguide.net/node/view/6322/tree to reflect this. Because this "new" Taxonomy is at odds with Dunkle I have made a crude amendment to the page to reflect this. I strongly believe that we have to recognize the names in popular texts so that one can find biological information on a species. I figured it was simplest to make the changes and then open up the topic for discussion; we can always reverse the changes.
