Someone who knows a little about dragonflies told me that, most likely, this is a newly emerged dragonfly. And the wings (and body too) are colorless since they haven't dried yet. (The dragonfly looked like a piece of cellophane as it flew past me.) She said she was not expert enough to be able to guess what species it is. Does anybody here have that expertise? Please see also the close-up image. Thanx.
