The blue ringtail (Austrolestes annulosus) is an Australian damselfly. It is found on most of the continent.
The abdomen is 3 cm long. It can easily be confused with Coenagrion lyelli or Caliagrion billinghursti, but can be differentiated through dorsal patterns. They are a thin, medium-sized damselfly with varying coloration, which depends on maturity and temperature. However most are a striking blue with minimal black markings. Females are slightly more robust than males, and have a black and white/pale blue coloration.
