Taxonomy

The blue ringtail was first described by Edmond de Sélys Longchamps in 1862.[3]

Description

The abdomen is 3 cm long.[4] 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.

Distribution and habitat

It is widely distributed in most of Australia, except for the northern and north-eastern parts.[3] It is active through September to April in still water bodies such as riverine pools, lakes and ponds, including temporary pools.
