(Agriocnemis argentea)
Agriocnemis argentea is a species of damselfly in the family Coenagrionidae, commonly known as a silver wisp. It is a small damselfly; the male, when mature, is covered in a white pruinescence.It is endemic to northern Australia where it inhabits both still and flowing waters. The species name argentea is a Latin word meaning the colour of silver. In 1906 Robin Tillyard named this species of damselfly after the beautiful silvery white bloom covering of mature adults, which when flying appears as a bright silver streak, darting in and out of the grass. Agrilus is a genus of jewel beetles, notable for having the largest number of species (about 3000) of any single genus in the animal kingdom
