Griseargiolestes griseus is a species of Australian damselfly in the family Argiolestidae, commonly known as a grey flatwing. It is endemic to south-eastern New South Wales, where it inhabits bogs and seepages near small streams.
Griseargiolestes griseus is a medium-sized damselfly, black-green metallic in colour with pale markings. Adults can be strongly pruinescent on their body and tail. Like other members of the family Argiolestidae, it rests with its wings outspread.
The genus name Griseargiolestes combines the Latin griseus ("grey" or "pearl-grey") with Argiolestes, the name of a related genus, referring to the pale pruinescence seen in this group. In 1862, Hagen named the species griseus, also likely referring to this pale pruinescence.

GBIF citizen-science records
It is estimated from how often the Grey Flatwing is recorded against all the insects logged in Blue Mountains National Park (42 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
