American rubyspot

Unlike most damselflies, which favor still ponds, adults of this species perch along fast flowing streams and rivers instead.

The American rubyspot is a damselfly with a body length of about 38 to 46 mm. Males have a lustrous red head and thorax, a large red spot at the base of each clear wing, and an iridescent green abdomen, while females are duller green or copper with faint amber wing spots.

Unlike most damselflies, adults favor flowing water, perching on shoreline plants along streams and rivers with moderate to fast current rather than still ponds. Nymphs live among submerged roots and debris in the current, and adults fly from April into October.
