Argia moesta

Description

Argia moesta is a damselfly of the family Coenagrionidae. It is native to North America. It may be seen year-round in at least some of its range. The common name refers directly to the male's pruinosity, appearing to be covered with a powdery blue or grayish substance. Older males are more pruinose, and may even be more ash white than blue. The scientific name moesta, means sorrowful, and may refer to customs (such as those on Ash Wednesday) of dusting oneself with ashes to express sorrow or mourning.
