Australian blue riverdamsel

The Australian blue riverdamsel is a thin, delicate damselfly coloured blue and black. It flutters along rivers and streams in Australia and New Guinea. It is so new to science that it only got its own name in 2026.

How fast is it?
Fun facts
For many years people thought it was the same as a damselfly from Asia. In 2026 scientists showed it is a kind of its own.
The males have little claspers at the end of the tail, and their tips are deeply split. That is how experts tell it apart.
Its family usually lives at streams, rivers and still water where plants poke up out of the water.
Its group name, Pseudagrion, means false Agrion. Agrion was the old name once given to all damselflies.
