There used to be a lady on the pond forums named GoNative. She was a dragon/damselfly expert, and so sweet. She was not well, and passed away a few years back. I sure miss her bright spirit but am glad we got to share her love of ponding and her wealth of knowledge.
The large red one may be called a pond hawk. Not sure. For years we have mostly had the little blue opr green damselflies. I get so excited when we get a big dragonfly here!!
