Ebony Jewelwings occur across much of the eastern United States and southern Canada. They can be abundant along shady streams and rivers. I took these photos on 6 June 2016 in the Carleton College lower arboretum. The first image is of a male. Females have a white spot on their wings.
These damselflies have a long flight season, from May through October (and all year in southern parts of their range). Individual adults, however, survive only a couple of weeks (Dragonfly ID). Ebony Jewelwings were among the first odonates I discovered during my dragonfly odyssey.
