This species is also known as butterfly damselfly because of its slow flying rate, flapping its winds like a butterfly. It is very distinct from other damselflies. It like woodland edge but strongly prefer sunny spots. They like to gather in groups in midsummer. I often get one or two in my yard from some group that usually gather near a nearby creek. They prefer to lay their eggs near shaded small streams, creeks, or whatever you call them. The creek near my house are about 3 to 4 feet wide but shallow and sandy bottom with only hair algae as the only aquatic vegetation on rocks and I have never seen fish in it.
The males have their wings all dark brown while the females have the white marks on them.
