I visited the swamp meadow again looking for more Grass Pinks and Rose Pogonias as well as whatever I could find. One of the “whatevers” was this damselfly, the Ebony Jewelwing-Calopteryx maculata. The white spot on the wings, called a stigma, tells us that this is a female.
I was lucky that this one set for a spell. They usually are pretty skittish.
