Fortunately, I had my 70-200mm lens on the camera, coupled to a 25mm extension tube. I use that setup a fair bit for plants, but it's also great for dragonflies. I was able to crawl on in, get prostrate, and shoot the cool insect at its level.
Stream cruiser! A new one for me, and in a completely unexpected bit of serendipity. While this species often patrols low over the waters of small streams - there was a creek not far off - they'll also hunt over nearby meadows, as we observed.
