Orthetrum pruinosum, the crimson-tailed marsh hawk, is a species of dragonfly in the family Libellulidae. It is a widespread species occurring from west India to Japan and south to Java and the Sunda Islands. A molecular phylogenetics study of Orthetrum dragonflies revealed that Orthetrum pruinosum is a cryptic species.

GBIF citizen-science records
It is estimated from how often the Crimson-Tailed Marsh Hawk is recorded against all the insects logged in Guangzhou (86 verified sightings), 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.
