I’ve been trying to take a picture of one of these for some time. Usually they flit around so abruptly, and stay put for such a short time when they land, that I can’t get them in focus. But this one posed on this fence for several minutes, only moving from one picket to another, and staying still for a bit on each one. It isn’t as pretty as some, but at least it’s pretty much in focus. (You need to view the full-size image to really see it.) I have a number of very fuzzy pictures that I took last summer of a brilliant green one.
I was very surprised to discover (via the Wikpedia entry) that dragonflies are considered somewhat sinister in some parts of Europe. I’v always seen them as graceful and benign. I was even more surprised to discover the existence of an activity called oding, which is to dragonflies as birding is to birds.
