Thanks again Geodialist. I was hoping you would confirm. I am slowly learning to ID in general then what to look for to become more specific. Again I am putting your comment in Notes so they are not lost to me.

You are correct, Gatorfellows. This dragonfly is an immature male as indicated by its terminal appendages: there are two superior appendages (cerci); and one inferior appendage (epiproct).
