Nice photos. Good sharp focus. I find that a challenge, partly due to changing eyesight, small subjects, and the low, or sometimes wide range light conditions I find myself in with a camera in my hand. I have seen very few of the Appalachian orchid species, but found numerous rattlesnake plantain and a single twayblade on a walk in the woods of Athens County, OH this past weekend. The twayblade was nearly spent; we were luck to see it. I hadn't even heard of it before. Very strange and lovey plant. Any idea who pollinates it (which insect)?
