We saw this insect in the park.  Its color was so vibrant, we had to stop.  It held still for a full minute!!!  I used my new favorite app SEEK, and it called it Beautiful Demoiselle.  Had to look it up.  According to SEEK, scientifically it is Calopteryx virgo, or European damselfly.  
 

According to Wikipedia, Calopteryx virgo lives in Europe.  'The distribution of the beautiful demoiselle covers all of Europe with the exception of the southwestern Iberian Peninsula, the Balearic Islands and Iceland.  On the North African Mediterranean coast, its southern populations in Morocco and Algeria can be found.'  No mention of Southern Appalachia.  
 

I sent an email to iNaturalist, SEEK's creators, and asked about other damselflies in our area, and I got this back:  'Seek's image recognition model doesn't take location into account, it relies purely on visual similarity,'  plus a link to four species of damselfly spotted in north Georgia.  This one is probably Superb Jewelwing, Calopteryx amata.  Ya gotta love that!!!!
 

I love this app even more now!!!  Information AND support!!  Did I mention that's it's free?  
 

Whatever species it is doesn't really matter to me;  we were just captivated by its beautiful iridescence.  And now you get to see it too.  Maybe you'll see some in your travels.  I hope so.  They are so beautiful:  superb, in fact.  
 

 

HAPPY GARDENING!!!
